6 SR Adoro In view of the versatile application possibilities of veneering composites, we have made it our objective to develop a universally applicable material system that demonstrates excellent aesthetic characteristics and physical properties. Our aim was to develop a material that not only offers a wide variety of design options for experienced specialists but also enables first-time users and all-rounders to use the various materials flawlessly and, above all, to process them efficiently and economically. The main thrust of the development work on SR Adoro has been towards designing a material that offers optimal physical properties, excellent aesthetics, convenient handling characteristics and ample flexibility. Particular emphasis has also been placed on coordinating the individual components of the SR Adoro system with each other as well as with other Ivoclar Vivadent systems (e.g. IPS d.sign or IPS InLine ). Material SR Adoro has been designed from scratch. The result is a composite veneering system that offers several advantages over hybrid composite materials as regards wear, handling, plaque resistance and surface finish. The advantageous properties of SR Adoro can be attributed to the high proportion of inorganic fillers in the nanoscale range. Furthermore, the matrix is based on a urethane dimethacrylate (UDMA), which has also been newly developed and which is characterized by its toughness, which is higher than that of its predecessors or the frequently used Bis- GMA. In order to achieve a non-sticky, homogeneous consistency and a low-shrinkage system a special prepolymer has been developed, which is also based on the newly developed UDMA and nanoscale fillers. The result is a virtually homogeneous material, which may well be called a microcomposite. Ivoclar Vivadent, who fostered the idea of integrated systems many years ago, has further complemented its product range by introducing SR Adoro. A coordinated range of products, encompassing alloys, metal-free framework materials, ceramics, denture teeth, light furnace, cements and composite veneering materials, enables the dental technician to cover the entire range of prosthetic reconstructions, from fixed and removable to combined denture prosthetics. A well-balanced basic kit, based on the Chromascop and A-D shade guide, and various complementary assortments allow the dental technician to design highly aesthetic reconstructions to replace lost tooth structure. 500 µm 6

7 Physical properties of SR Adoro The inorganic microfillers, combined with the newly developed matrix, impart a homogeneous structure to the material. The ratio between these two components has been carefully adjusted, endowing the material with excellent physical properties and a high resistance to discoloration, plaque and wear. Aesthetic properties of SR Adoro Highly aesthetic results can be achieved even if a straightforward, basic layering procedure is used thanks to the excellent aesthetic properties of the material. Even the basic material of SR Adoro exhibits opalescent characteristics, which are equal to those of the natural tooth in every way. Watchwords, such as brightness, chroma, or opacity and translucency, have been taken into account in the coloration of SR Adoro. These characteristics are apparent in the individual components of SR Adoro and endow the material with its highly aesthetic properties.

8 PRODUCT SYSTEM Compatibility with Ivoclar Vivadent alloys All metal-supported restorations involve the veneering of a previously fabricated metal framework. Ivoclar Vivadent offers customers a wide range of different high-quality alloys, which are purpose designed for their specific field of application. The selection of alloys encompasses high gold, reduced gold and base metal alloys. The SR Link bonding system provides a sound bond between the metal and composite. If you use other alloys, please contact the corresponding manufacturer to make sure that the alloy used is compatible with SR Link and its components. Alloys High Gold content: Academy Gold Harmony PF Academy Gold XH Reduced Gold content: Harmony XH XL-X Maxigold Midigold 50 Magenta Minigold Universal alloys BioUniversal PdF Base metal alloys IPS d.sign 30 Pisces Plus 4all Au Pt < Co Ni Cr Mo Pd Ag Compatibility with IPS d.sign and IPS InLine The basic shade systems of SR Adoro, IPS InLine, IPS e.max Ceram, consisting of opaquer, dentin, deep dentin, incisal and transparent incisal materials, correlate with the IPS d.sign shade system. This means that an opaquer, dentin, deep dentin and a matching incisal material are available for each shade. In addition, the shading of the Impulse, Gingiva and Stains materials of IPS d.sign was adopted so that the additional materials, which are independent of any shade system, produce a similar aesthetic appearance as that achieved with the IPS d.sign materials. This allows users to work more efficiently. Furthermore, the time-consuming adjustment process from the ceramic to the composite shade system is no longer required. Consequently, the processing procedures in the fabrication of combined restorations are easier and faster and shade matching to existing ceramic restorations is more efficient. The range of products on offer may vary from country to country. 8

9 Compatibility with Ivoclar Vivadent tooth lines In partial and removable prosthodontics, the compatibility between denture teeth and composite veneering material plays a particularly essential role. For this reason, we paid particular attention to developing a material that is capable of reproducing the shade of the Ivoclar Vivadent denture teeth. The shades of the purpose designed SR Adoro cervical materials are matched to the PE shade guide (SR Vivodent, SR Orthotyp) and the A D shade guide. Accurate shade matching is particularly vital in crowns with thinning margins (e.g. telescopes), which imitate the cervical area of the denture tooth. In addition, SR Adoro can be used to modify the shade and shape of Ivoclar Vivadent denture teeth for true-to-nature results. Compatibility with Ivoclar Vivadent luting systems Select one of the tried-and-tested cements from the Ivoclar Vivadent range. Suitable luting composites or cements are available for both the adhesive cementation of metal-free restorations and conventional cementation of metal-supported restorations. Metal-free restorations: Variolink Veneer Variolink II Multilink Automix PRODUCT INFORMATION Compatibility with Ivoclar Vivadent equipment The high-quality composite restorations are polymerized/tempered in the high performance Lumamat 100 furnace. The newly designed object holder ensures that the SR Adoro restorations are appropriately positioned for optimum polymerization/tempering so that they can develop their physical properties to the full. The sensor controlled Quick light unit can be used for fast precuring processes. The Quick unit can also be utilized to precure other light-curing veneering materials.

Composite veneering materials show specific characteristics and properties and their performance and durability can therefore not be compared with that of other C&B materials. The composite restorations may require clinical repair over time, depending on the situation of the individual case. The restorations can be repaired by means of microfilled composites, as described in the section on Subsequent adjustments on page 99.

11 QUESTIONS AND ANSWERS about SR Adoro Thermo Guard What is SR Adoro Thermo Guard? SR Adoro Thermo Guard is a diethylene glycol/water based paste. The paste is applied to exposed metal surfaces to achieve a thermally absorbing (cooling) effect, which minimizes the tension at the interface between the metal and SR Adoro. In which situations do you have to apply SR Adoro Thermo Guard? SR Adoro Thermo Guard has to be applied to all metalsupported restorations. Further, SR Adoro Thermo Guard is utilized to cover resin saddles in combination prostheses and to repair metal-supported restorations. Why is it necessary to use SR Adoro Thermo Guard? SR Adoro is a light- and heat-curing veneering composite rather than being purely light-curing. Only if the material is tempered with both light and heat (thermal treatment) does it develop its optimal material properties and surface quality. Because a high tempering temperature of 104 ºC is used, the CTE values play a crucial role, similar to the processing of ceramics for instance. The CTE s of composites and alloys significantly differ from each other (alloys: approx x 10-6 /K, SR Adoro 60 x 10-6 /K). The application of SR Adoro Thermo Guard enables an even preheating, tempering and cooling phase during the light/heat tempering procedure. Consequently, the risk of hairline cracks is reduced. What happens if SR Adoro Thermo Guard is not applied? Because of the different CTE values and thermal conductivity of the materials (metal = high thermal conductivity, composite = low thermal conductivity, i.e. insulator), failure to apply SR Adoro Thermo Guard leads to an uneven preheating, tempering and cooling phase. Internal tension may develop and discharge during the light/heat tempering procedure or at a later stage. In the process, microscopically small hairline cracks, may occur. Does SR Adoro Guard have to be applied again if a metal-supported restoration is tempered a second time? SR Adoro Thermo Guard has to be applied to metal-supported restorations prior to all final tempering and repeat tempering processes performed at 104 ºC for 25 minutes in the Lumamat 100 or Targis Power Upgrade. How can hairline cracks in composite restorations be prevented? Always observe the depth of cure; build the restoration up in small amounts; observe the recommended times for precuring; separate the proximal surfaces of individual bridge components as is usually done in conjunction with other light-/heat-curing or pressure-/heat-curing veneering composites. If hairline cracks have formed nevertheless, they can be repaired in the usual manner, as described in the section on Subsequent Adjustments. PRODUCT INFORMATION How does SR Adoro Thermo Guard work? By applying SR Adoro Thermo Guard on all exposed metal portions, the metal cannot heat up as strongly as the ambient temperature and the veneering composite. The thermally absorbing (cooling) effect of SR Adoro Thermo Guard helps minimize the internal tension at the interface between the metal and SR Adoro. Consequently, the risk of hairline cracks is reduced. Where should SR Adoro Thermo Guard also be used? SR Adoro Thermo Guard is utilized to cover denture saddles in the fabrication of combined dentures and to carry out repair work. SR Adoro Thermo Guard prevents denture saddles (thermoplastic) and denture teeth from deforming during the light/heat-tempering process in the Lumamat 100 or Targis Power Upgrade. SR Adoro Thermo Guard minimizes the risk of hairline cracks. However, as with other light-, light/heat-, and pressure/heat-curing composites this risk cannot be completely eliminated. 11

12 Questions and answers regarding the processing procedure What is the correct connector thickness in metal-supported bridges? In what furnaces can SR Adoro be polymerized/tempered? FRAMEWORK FABRICATION The connector area between the abutment of bridges should measure at least 3 x 3 mm. How should SR Link be stored? After delivery, SR Link should be kept in the refrigerator (2 8 ºC). On what alloys can SR Link be applied? alloys that contain up to 90% gold, palladium and platinum alloys that contain up to 50% copper and/or silver base metal alloys titanium alloys Can SR Link be applied to high gold and copperfree bio alloys and Galvano formed frameworks? Bio alloys contain a high content of precious metal (Au, Pt, Pd, Ag), while electroformed restorations comprise a high content of pure gold (99.9%). Consequently, SR Link cannot be used in conjunction with these materials. What has to be observed when performing the blasting (conditioning) process? Use Al2O3 with a grain size of microns and a maximum pressure of 3 bar (see page 32). P OLYMERIZATION Only Targis Power Upgrade and Lumamat 100 furnaces must be used to polymerize/temper SR Adoro. What happens if the curing depths are not observed? If the recommended curing depths are not observed, the material can no longer be completely polymerized/tempered. As a result, delamination may occur. At what distance from the Quick initial curing light should the layers be precured? The smaller the distance between the bulb of the curing light and the layer, the higher is the curing depth of the material. Under no circumstances should the distance be larger than 2 cm. Does SR Gel have to be used every time? SR Gel has to be used every time when SR Adoro is tempered in the Targis Power Upgrade or Lumamat 100 to prevent the formation of an excessively thick inhibition layer. Thick inhibition layers may result in clinical failure of the restoration. Is it possible to use working models with acrylic base plates? In view of the high polymerization/tempering temperature of 104 ºC, we advise against using such working systems. How can the polymerization/tempering temperature of 104 ºC be checked? Calibrate the furnace on a regular basis using the L 100 test set. Observe the corresponding Operating Instructions. Can restorations be polymerized/tempered while they are placed on the model? LAYERING Can the SR Adoro pastes (high and low viscosity) be mixed with each other? High and low viscosity pastes must not be mixed with each other as this would lead to bubbles in the mixed materials. SR Adoro must not be mixed or processed with other veneering materials. In what layer thickness can SR Adoro be applied? A layer thickness of 2 mm must not be exceeded in the incisal and occlusal area. Can SR Adoro Stains be applied to the outer surface? Basically, the following rule applies: The smaller the amount of material in the furnace (on the object carrier), the more controlled the polymerization/tempering process. Consequently, it is advisable to remove neighbouring units from the model when polymerizing/tempering metal-free restorations to reduce the amount of material present in the furnace. When fabricating a metal-supported restoration, only mount the object on the object carrier, if possible. The maximum weight of the working model must not exceed 400 g (corresponds to a large working model and a split cast base). Does the colour of the plaster (e.g. blue, brown, white, etc.) affect the polymerization/tempering result of SR Adoro? Always cover SR Adoro Stains with a layer of incisal or transparent material. The colour of the plaster does not have any effect on the polymerization/ tempering result. In other words, any plaster colour can be used. Is it necessary to use connector and bonding liquids when applying additional modifications? Do not use connector or bonding liquids as they may diminish the bond of SR Adoro. Is it possible to carry out intermediate polymerization cycles? Yes, program 2 can be used for intermediate polymerization of dentin layers for instance (in conjunction with SR Gel). After completion of the intermediate polymerization cycle, the restoration is cut back and thoroughly cleaned (no blasting) before proceeding with the layering procedure. Do not use bonding and/or connector liquids. 12

15 CURING DEPTHS Given the material s sensitivity to light, the curing depth of SR Adoro (i.e. precuring with Quick initial light unit) depends on the shade and, above all, the layer thickness applied. Light and translucent shades cure more readily, as light can penetrate them more easily than it does darker and more opaque shades. The curing depths listed below represent values achieved in a precuring step of 20 seconds using the Quick light unit. It is paramount to bear these values in mind when layering the individual materials.

19 DESCRIPTION OF KITS SR Adoro Basic Kits PRODUCT INFORMATION SR Adoro Basic Kit Chromascop SR Adoro Basic Kit A D SR Adoro Liner The Liner are used as the basic shade in metal-free restorations. The liner can also be used in inlay/onlay restorations to block out dark areas, such as discolorations and linings/bases. Furthermore, the liner provides a reliable bond between the restoration, composite cement and prepared tooth. The liner is available in 6 shades to suit all Chromascop and A D shades. The shade combinations are shown on the label. The Liner clear is utilized for inlay/onlay restorations to mask the remaining areas of the cavity that are still uncovered. This material helps to achieve a lifelike chameleon effect. The new Liner incisal exhibits slight pigmentation and is mainly applied for inlays/onlays along the preparation margin. This liner provides a harmonious transition between the restoration and natural tooth structure, preventing the formation of a grey line. In addition, the liner can be used for the cervical region in crown restorations to enable light to reach this area, creating a natural looking transition between pink and white aesthetics. SR Adoro Opaquer The opaquer pastes are provided in Chromascop and A D shades. They provide excellent stability and a high masking capability, even if applied in thin layers. They also promote a reliable bond to SR Link and the veneering composites. SR Adoro Intensive Opaquer These intensive opaquer pastes are available in 4 shades and are suitable for applying individualized characterizations in the opaquer areas. The pastes are particularly useful for stabilizing the shade in cervical and incisal regions. 19

20 SR Adoro Neck These cervical materials have been specifically developed for combined denture prosthetics to facilitate the adaptation of the composite veneers to the denture teeth. They are matched to the cervical shades of the Vivodent PE and A D shade guides and can consequently be used in conjunction with the SR Vivodent PE and SR Orthotyp PE tooth lines. SR Adoro Dentin The dentin materials form the basis of the Chromascop and A D shades. Their degree of translucency/opacity is adjusted to their specific field of application (i.e. metal-supported and metal-free restorations). SR Adoro Incisal The translucency/opacity of the SR Adoro Incisal materials resembles that of the natural tooth as well as the IPS d.sign, IPS InLine Incisal material. These materials are mainly used for the shade build-up according to the Chromascop shade guide. The materials exhibit a lower degree of translucency and are brighter than the SR Adoro Transpa Incisal materials. SR Adoro Transpa Incisal The translucency/opacity of the SR Adoro Transpa Incisal materials resembles that of the natural tooth as well as the IPS d.sign, IPS InLine Incisal Transpa material. They are primarily intended for the shade build-up according to the A D shade guide. They demonstrate a higher degree of translucency and a lower degree of brightness than the SR Adoro Incisal materials. SR Adoro Transpa clear This entirely transparent material provides a slight opalescent effect, enabling the true-to-nature reproduction of highly translucent areas, as can be found in natural teeth. SR Adoro Transpa clear is the most translucent of all SR Adoro materials. SR Adoro Add-On It is often necessary to apply quick minor adjustments after the restoration has been tempered or completed. The add-on material features a medium degree of incisal opacity and offers short working and tempering times. It must only be used to apply minor adjustments, such as proximal contact points or pontic inserts. 20

27 SR ACCESSORIES SR Link, 5 ml SR Link is a metal-composite bonding agent that provides a covalent bond between the metal framework and SR Adoro. SR Link is an easy-to-use and, above all, tried-and-tested bonding system that can be used in conjunction with a wide selection of alloys. The bonding agent is suitable for use in conjunction with metal frameworks made of: alloys that contain less than 90% gold, palladium and platinum alloys that contain less than 50 % copper and/or silver base metal alloys titanium alloys SR Link must not be used on electroformed (Galvano) frameworks, as the reactivity of the components partaking in the chemical reaction decreases with increasing contents of precious metal. Consequently, not enough metal-phosphate bonds are formed. SR Gel, 30 ml SR Gel is a glycerine-based masking gel that is impervious to oxygen. The gel is applied to the restorations before final polymerization/ tempering to minimize the formation of an inhibition layer on the surface of the veneering composite. Consequently, the gel ensures complete curing of restoration surfaces. SR Adoro Thermo Guard, 175 g SR Adoro Thermo Guard is a diethylene glycol/water based paste. The paste, which is applied to all exposed metal parts before final polymerization/ tempering, provides a thermally absorbing (cooling) effect, thereby minimizing the internal tension at the interface between metal and SR Adoro. As a result, SR Adoro Thermo Guard helps reduce the risk of hairline cracks. SR Model Separator, 10 ml The SR Model Separator is suitable for separating working dies during the fabrication of metal-free restorations and adjoining stone surfaces during composite veneering. SR Retention Adhesive, 20 ml This adhesive varnish is utilized to affix microand macroretention beads to the surfaces of restorations after modelling. SR Microretention Beads, 15 ml SR Macroretention Beads, 15 ml Two different sizes of retention beads are available, depending on the space available. microretention: microns macroretention: microns SR Mixing Pad, small SR Mixing Plate, small The SR mixing pad and SR mixing plate are used for different materials. The pad is mainly used to process liquid materials so that time-consuming cleaning of the plate can be avoided. By contrast, the plate is used to mix the composite components. The light protective cover of the plate extends the working time of the materials. SR Modelling Instruments A (yellow), B (red), C (blue) The classic Ivoclar Vivadent modelling instruments for composite materials, which are provided in a new userfriendly design, facilitate the adaptation and contouring of composite materials. They are available in six different shapes and can be used for a variety of applications. Universal Polishing Paste, 100 ml This universal polishing paste enables quick and efficient polishing of composite and metal restorations to a high gloss. The paste is particularly suitable for prepolishing and principal polishing of SR Adoro veneers. PRODUCT INFORMATION 27

28 SR Composiv, 2.5 g This ivory-coloured bonding paste is the ideal light-curing microfilled composite to optimize the bond of various resins and composite materials. The paste is applied to promote the bond between Ivoclar Vivadent denture teeth and SR Adoro veneering material in particular. Cannulas, 10x These application tips can be attached to Liner, Opaquer and Stains syringes. They help achieve more accurate dosing and cleaner application procedures as the extrusion pressure can be controlled. Universal Holder The universal holders are employed to handle disposable brushes and sponges and thereby help to facilitate the working procedures in the dental laboratory. Cannula Caps, 20x The cannula caps prevent the material from drying out or polymerizing prematurely while it is in the cannula and provide protection against contamination. Disposable Brush, 50x The disposable brushes are particularly suitable for the application of liquid materials, such as SR Model Separator, SR Link and SR Adoro Opaquer. Disposable Sponges, 50x The disposable sponges have been modified to fit into the universal holder. They are used to remove the inhibition layer after polymerization of the opaquer and liner. 28

30 SHADE SELECTION The Chromascop shade guide represents the shade standard for Ivoclar Vivadent products. With the logical arrangement of the individual shades, the Chromascop permits exact and efficient shade determination. The 20 shades are divided into five detachable shade groups. Once the basic shade has been selected, the correct shade within the shade group can be determined. Consistently ignoring any superfluous effects (e.g. cervicals, transparent areas, intensive disolouration in the incisal and dentin areas as well as surface characterizations) greatly helps determine the correct shade. SR Adoro Individualized shade determination It goes without saying that the materials shade guides are an integral part of the SR Adoro system. The dentin shade tabs feature a textured surface and anatomic shape for light refraction purposes. The other shade tabs are slightly wedgeshaped to take account of the translucency of the individual materials. All shade tabs feature a smooth, i.e. untextured reverse side to assist users in comparing the shades against the prepared tooth and coloured cements and adhesives. The smooth side of the shade tabs can be cut with a grinding instrument to reveal the colour effect in thinner layers. The shade tabs are made of ceramic to ensure colour stability. They are fired of specially coloured ceramic materials to ensure that they comply with the individual SR Adoro materials. As the materials shade guides have been modelled on the IPS d.sign, IPS InLine shade guides, the sample holders of the SR Adoro shade guides are coloured light grey to distinguish them from the IPS d.sign, IPS InLine shade guides. 30

31 PREPARATION GUIDELINES/MINIMUM THICKNESSES FOR METAL-FREE SR ADORO RESTORATIONS As metal-free SR Adoro restorations are luted in place using an adhesive cementation method, a tooth-conserving and defect-oriented preparation technique can be used. Inlays Provide a preparation depth of at least 1.5 mm in the fissure area (central fissure). The isthmus width should be at least 1.5 mm. The walls of the box should be slightly flared. Round out internal line angles to enable an accurate fit of the inlay. Avoid preparation margins in occlusal contact areas. Avoid proximal contact areas. Do not prepare slice-cut or feather edge margins. 1,5 Onlays Allow for a preparation depth of at least 1.5 mm in the area of the fissures, an isthmus width of at least 1.5 mm and provide 1.5 mm space in the area of the cusps. The shoulder may be prepared with an incline (10 30º) to enhance the aesthetic appearance of the transitional area between the composite and tooth. An onlay preparation is indicated if the preparation margins are no more than 0.5 mm away from the cusp tip or if the enamel is severely undermined. 1,5 > WORKING PROCEDURE 1.5 1,5 1, Veneers If possible, the preparation should be entirely located in the enamel. Two preparation designs are possible. The first involves a wraparound technique onto the lingual surface and the other stopping at the top of the incisal edge. The incisal margins should not be located in occlusal contact areas. The minimum preparation thickness is approx mm, depending on the preparation technique chosen. Eliminating proximal contacts is not necessary. Discoloured teeth may require more extensive reduction, depending on the degree of translucency desired. The more translucent the incisal edge of the veneer should appear, the more reduction is required. 0,6 0, Anterior crown Evenly reduce the anatomical shape and observe the stipulated minimum thickness. Prepare a circular chamfer/shoulder with rounded inner edges. The width of the chamfer/shoulder should be at least 0.8 mm. For anterior crowns, the labial and/or palatal/lingual surfaces should be reduced by at least 1.0 mm. Reduce the incisal crown third by at least 1.5 mm. Prepare smooth, rounded transitions so that no internal line angles or edges are present

33 1. Framework design for full-coverage veneers (ideal space available) The framework for full-coverage veneers should reflect the shape of the tooth in a reduced form. The framework should be designed in such a way that it supports the cusps so that an even layer of the veneering composite can be used in the cusp/fissure area. In this way, the masticatory forces are exerted on the framework rather than on the veneering composite. In large preparations, the missing tooth structure must be compensated by the design of the framework and not the veneering composite. Furthermore, an even layering thickness facilitates the creation of a harmonious shade effect, while full-coverage veneering provides a maximum level of aesthetic beauty and function. All areas of the framework should be smooth and rounded to prevent delamination and cracking. Angles and edges should be rounded out already in the wax-up and not in the metal in order to avoid undermining the minimum framework thickness. The wall thickness of the metal framework for single crowns should be 0.3 mm and 0.5 mm for bridge abutments after finishing. Anterior crowns WORKING PROCEDURE Premolar crowns Molar crowns 33

34 2. Framework design for partial veneers (limited space available) A different framework design is required for partial veneers (e.g. telescope and conus crowns). As the space in the palatal and lingual area in particular tends to be limited in many cases, this area of the restoration must be designed in the metal in such a way that cracks or delamination cannot occur because of inadequately thin layer thicknesses of the veneering composite. The transition margin between the metal framework and the veneering composite should be clearly defined and it should incorporate a right angle finish line. The transition areas between the metal framework and the veneering composite must not be located in the area of contact points or on surfaces involved in masticatory functions. A chamfer or wraparound technique is required in partial veneer preparations to provide adequate support for the veneer. Observe the palatal area in upper canines (canine guidance) and the occlusal area in posterior teeth. To obtain a balance between aesthetic and functional properties, it is advisable to reduce the mesial corner of the occlusal surface in upper posterior teeth in particular to attain a harmonious aesthetic appearance, especially when the buccal corridor is exposed. The wall thickness of metal frameworks should not be less than 0.3 mm for sinlge crowns and 0.5 mm for bridge abutments after finishing. Please see the Instructions for Use of the alloy used for further information. Anterior crown Premolar crown Molar crown 34

35 3. Design of bridge pontics Bridge pontics are designed taking aesthetic and functional aspects as well as oral hygiene into consideration. The area of the pontic that contacts the alveolar ridge should be made entirely of metal (polished to a high gloss) or composite. The transition between the metal and composite should always be located in an area where efficient oral hygiene is ensured. If adequate space is available, the contact area is made of composite. In order to ensure adequate stability between the bridge pontic and bridge abutment, a palatal and/or lingual scallop is recommended. If space is limited, the contact area is made of metal burnished to a high gloss. The palatal and/or lingual areas are made of metal to ensure adequate stability. To prevent shrinkage cavities from forming in extensive pontics, it is advisable to hollow out the pontic. A wax wire is placed in the hollowed space (ample space available) and formed in such a way that it is level with the abutment teeth. This measure provides additional retention and helps achieve an even colour effect in the bridge pontic and abutment. Ideal space available Limited space available WORKING PROCEDURE 35

36 4. Interface between metal and composite The interface between the metal and composite must be clearly defined, incorporate a right angle finish line and use a chamfer or wraparound technique. The juncture between the metal framework and veneering material must not be located in the area of contact points or surfaces involved in masticatory functions. Furthermore, make sure that the interface in the marginal area does not come into contact with the gingiva, particularly if a tapered crown margin is used (i.e. no metal margin). In this way, irritation of the gingiva can be prevented. The interface in the interdental space should be designed in such a way that cleaning of these difficult-to-reach areas is possible. 5. Correct application of retention beads It is basically advisable to apply retention beads to provide mechanical retention in addition to the chemical bond with SR Link. If space is limited, it may not always be possible to apply retention beads or they may only be applied to certain areas. Retention beads can be applied locally to the bonding surfaces without compromising the space available or the aesthetic appearance of the restoration in particular. The SR Retention Adhesive should be applied in as thin a coating as possible so that the retention beads are not completely immersed in adhesive and enough surface area for mechanical retention is provided. After casting, the retention beads may be reduced by half of their size (equator) to preserve a sufficiently large retentive surface. Retention Adhesive (schematic) 36

39 CEMENTATION Adhesive cementation Adhesive cementation of metal-free restorations results in a tight bond between the restoration and prepared tooth. Such a bond enhances the fracture resistance of the restoration. The translucent shade of the adhesive and the virtually invisible margins promote the aesthetic appearance of the restoration. Conventional cementation Zinc phosphate, hybrid ionomer and glass ionomer cements can be used for the conventional cementation of metalsupported restorations.

44 STARTING SITUATION / FABRICATING THE FRAMEWORK Starting situation Fabricate a master model or a model with detachable segments on the basis of the impression in the usual manner. Expose and mark the preparation margin. It is advisable to apply a sealer to harden the surface and to protect the stone die from abrasion. The application of the sealer must not cause any changes in the dimension of the stone die. Next, a spacer may be applied in the usual manner. A model with detachable segments is used as the basis. The model is coated with sealer and spacer. Fabricating the framework There are two types of frameworks, i.e. frameworks for full-coverage veneers (ideal space) and frameworks for partial veneers (limited space). It is advisable to design a full wax-up and then fabricate a silicone key to check the space during contouring. When fabricating the framework, make sure that the minimum wall thickness after finishing is 0.3 mm for single crowns and 0.5 mm for bridge abutments. These dimensions are the prerequisite for a stable metal framework and a durable bond between the metal and composite. If the stipulated framework and connector dimensions are not observed, delamination and cracking may occur. Full contouring of anatomical shape. and fabrication of a silicone key for checking. 44

45 Contouring On the following pages, two versions of framework design are shown stage by stage up to and including the application of the opaquer (ideal and limited space). The framework introduced in version A will be veneered and completed. The framework should reflect the shape of the tooth in a reduced form (see page 33 for a modellation method that supports the tooth shape). As a result, the composite can be applied in an even layer and will consequently be appropriately supported. The requirements of the different alloys have to be taken into account. Version A Version B Full-coverage veneering (ideal space) Partial veneering (limited space) CROWN AND BRIDGE PROSTHETICS Reducing the framework on the labial and Reducing the framework only on the labial side. palatal side. On the palatal side, the full anatomic shape of the framework is maintained. Checking on the labial side. Shaping the wax wire in such a way that it is at level with the abutments. If the metal framework is too small, the veneering composite is not adequately supported, which may lead to cracks, delamination and aesthetically compromised results. 45

46 Application of retention beads Aesthetic and functional criteria need to be taken into account when applying retention beads. First, attach the sprues, then apply a thin coat of SR Retention Adhesive and carefully remove the restoration from the model. Allow the SR Retention Adhesive to dry for at least 20 seconds to enable the solvent to evaporate and to ensure that the retention beads do not sink into the adhesive and stop providing mechanical retention. It is advisable to place retention beads extensively on frameworks that will be fully veneered (ideal space), while retention beads should be applied locally to frameworks that are only partially veneered (limited space). After casting, the retention beads may be reduced by half of their size (equator) to preserve enough retention surface. Apply a thin fully covering coat of SR Retention Adhesive and allow to dry for at least 20 seconds. Version A Full-coverage veneering (ideal space) Version B Partial veneering (limited space) Sprinkle retention beads over the labial. Apply retention beads locally. and palatal surfaces. Mechanical retention increases the bond strength between metal and veneering composite. The retention beads produce an irregular surface. After the application of the opaquer, this will result in increased light scattering and an enhanced aesthetic appearance. After having used SR Retention Adhesive, surfactant must not be applied to the framework prior to investing it with investment material. The surfactant may dissolve the adhesive varnish. 46

47 Casting and finishing After having cast the framework (e.g. with Academy Gold XH), carefully divest, sandblast and/or clean it and fit it to the model. After separation, the cast framework is finished using tungsten carbide burs. It is advisable to use reduced pressure when working with softer alloys. A correct marginal design is paramount to attaining a reliable composite-metal bond. If possible, apply a tapered chamfer or wraparound design in the cervical area. Version A Full-coverage veneering (ideal space) Carefully divest, sandblast or clean Version B Partial veneering (limited space) CROWN AND BRIDGE PROSTHETICS and fit to the model. Using a tungsten carbide bur, create a tapered cervical margin, preferably by using a wraparound technique or a chamfer. Polish metal portions that are not veneered to a high gloss. 47

48 CONDITIONING OF THE FRAMEWORK Conditioning with SR Link After finishing, carefully blast the framework with type 100 Al2O3 at 2 bar pressure (see page 32 and the Instructions for Use of the alloy used). Blasting improves the mechanical bond. It results in the surface being roughened and substantially enlarged. After blasting, remove residue by tapping it off and not by cleaning with steam or an air gun. Apply SR Link immediately after having tapped off residue. Use a clean disposable brush to apply SR Link and allow to react for 3 minutes. Do not soak metal surfaces in SR Link. Carefully blast with type 100 Al2O3 at 2 bar pressure. After blasting, do not clean with steam nor with an air gun instead tap off residue with an instrument. 48

49 Version A Version B Full-coverage veneering (ideal space) Partial veneering (limited space) Bridges placed on the model after completion of the blasting and conditioning procedure. CROWN AND BRIDGE PROSTHETICS SR Link is applied immediately after the blasting procedure, using a disposable brush. Allow SR Link to react on the conditioned bridge for 3 minutes. When using SR Link, do NOT clean the frame work with steam OR with an air gun after blasting. Do not touch cleaned surfaces. Do not use SR Link in conjunction with alloys that contain more than 50% silver and/or copper or alloys with more than 90% gold, palladium and platinum. 49

50 APPLICATION OF OPAQUER 1 st opaquer layer (wash) Remove the desired amount of opaquer paste from the syringe and slightly spread out on a mixing pad using a disposable brush. Apply the first opaquer layer (wash) thinly using the brush. Smooth out any roughness and make sure that the retention beads (micro- and macroretention) on the metal surface are well surrounded with opaquer, since the wash is the most important bonding surface between the metal and composite. Precure each segment for 20 seconds, using the Quick curing light. Version A Full-coverage veneering (ideal space) Version B Partial veneering (limited space) Apply 1 st opaquer layer (wash) thinly, using a disposable brush smoothing out any roughness and filling up the gaps between the retention beads.

51 2 nd opaquer layer and building up of the bridge pontic Apply the second opaquer layer in such a way that the metal framework and the retention beads in particular are completely covered with opaquer, i.e. as much as necessary and as little as possible. Next, precure each section for 20 seconds with the Quick light curing unit and then polymerize directly in the Lumamat 100 or Targis Power Upgrade (program 2/11 minutes). Four Intensive Opaquers are available for individual customization. The degree of brightness can be heightened by applying Intensive Opaquer white. Version A Full-coverage veneering (ideal space) Building up the bridge pontic Apply the second opaquer layer in such a way that the metal framework is completely covered with opaquer and precure each segment for 20 seconds. Next, build up the hollowed out space on the bridge pontic to the level of the abutment teeth using Transpa clear and precure for 40 seconds using the Quick curing light. Then, apply a layer of opaquer directly on the inhibition layer of Transpa clear and precure for 20 seconds. Subsequently, polymerize in the Lumamat 100 or Targis Power Upgrade with program 2. Version B Partial veneering (limited space) CROWN AND BRIDGE PROSTHETICS Apply the second opaquer layer in such a way that it completely covers the retention beads Apply second opaquer layer customize using the Intensive Opaquer pastes build up bridge pontic with Transpa clear, check against the silicone key, light cure for 40 seconds and light cure each segment for 20 seconds. and completely cover with Opaquer. 51

52 POLYMERIZATION OF THE OPAQUER To obtain a smooth transition between metal and composite, thin out the opaquer at the metal margin. If a smooth surface is preferred, lightly tap top of the surface with a spatula Check opaquer for complete polymerization in critical areas, using a probe. Mount the restoration without the model on the object holder. Polymerize the restoration without the model, using program 2.

53 PREPARATION FOR DENTIN / INCISAL LAYERING Sealing the model Before building up the Dentin and Incisal materials, all parts of the model that may come into contact with SR Adoro are sealed. This step helps to prevent the composite from sticking to the model. Use SR Model Separator to seal adjoining parts of the model (e.g. stone die and contact surfaces of the pontic). Apply SR Model Separator in a thin coating, allow to react for a short time and remove excess with oil-free compressed air. Tip Characterizing the opaquer After the inhibited layer has been removed, you may customize sections of the opaquer surface with SR Adoro Stains. It is advisable to apply a thin layer of Stains in the marginal and interdental area, particularly if space is limited, to support the colour effect from the depth of the restoration. Subsequently, light cure SR Adoro Stains for 20 seconds with the Quick curing light. CROWN AND BRIDGE PROSTHETICS Removing the inhibition layer Thoroughly remove the inhibition layer using a disposable sponge (do not use a solvent), removing all residue from the opaquer surface. Make sure that the surface of the opaquer has a silky mat finish. Polymerizing characterizations Apparatus Time Program Curing time per section Quick 20 sec.

54 TIPS ON LAYERING Before layering, avoid folding the pastes to prevent air from being entrapped. Do not mix low and high viscosity materials with each other. It is advisable to apply Deep Dentin of the next brighter shade or highly opaque pastes, e.g. Mamelon light to the contact surface of the pontic to ensure adequate shade stability. Subsequently, cover this area with layers of Neck and/or Deep Dentin and Dentin materials. It is advisable to build up and precure the individual segments and veneers (tooth by tooth) separately from each other. Subsequently, join the individual veneers. Opal Effect provides a true-to-nature opalescent effect in the incisal third. Opal Effect 1 is applied to the dentin, which has been cut back, as an extension of the dentin core and then precured. Opal Effect 5 is used to create secondary dentin. Use the coloured Transpa materials to complete and heighten the vitality in the incisal area. Transpa blue is suitable for the lateral aspects on the mesial and distal sides of the tooth. Use mamelon materials to create a lifelike colour effect in the cervical third. The mamelon materials are applied to the incisal surface after the application of the Opal Effect materials. Create soft transitions; avoid edges. After the polymerization process, the edges may look like stubs and the mamelons may appear too conspicuous. 54

55 DENTIN / INCISAL LAYERING The individual SR Adoro pastes are applied according to the layering diagram (layering method according to shade guide) or as desired. Adapt the first layer firmly to the opaquer (press it into place) to ensure an effective bond between the composite and opaquer surface and precure each segment for 20 seconds using the Quick curing unit. Neck or Deep Dentin material may be applied in a half-moon shape to cervical areas, pontics and crown margins that are thinning towards the metal. Create smooth transitions between the layers (Neck-Dentin-Mamelon-Incisal), using SR modelling instruments and synthetic brushes. CROWN AND BRIDGE PROSTHETICS The pontic area is stabilized with Deep Dentin; Neck material may be applied in a half-moon shape to the cervical. Next, build up the dentin layers step by step and precure each segment for 20 seconds. The colour effect may be heightened in the interdental space by applying chromatic materials, such as Occlusal Dentin orange. Make sure to provide adequate space for the subsequent application of the Incisal and Transparent materials. The mamelons can be individually created either with Mamelon material or with SR Adoro Stains. After that, the restoration is completed layer by layer using Incisal and Transparent materials. The consistencies of the materials are coordinated with each other to facilitate the layering procedure and ensure that the contours are retained after shaping. As the Incisal materials are matched to the Dentin materials, even the most subtle transitions can be successfully achieved. Precure each individual layer for 20 seconds using the Quick curing light. Firmly adapt the first layer to the opaquer and then build up and precure layer by layer. It is crucial to adhere to the recommended curing depths and maximum layer thickness of the individual materials when carrying out the layering procedure. If the maximum layer thickness is exceeded, break up large portions into several layers and precure each layer for 20 seconds. 55

56 LABIAL LAYERING Heighten the colour effect in the interdental space by applying Occlusal Dentin orange complete the dentin core up to the mamelons build up incisal surface using Incisal materials; precure the individual layers with the Quick curing light complete with Opal Effect 1; add Mamelon material. 56

57 Complete the labial surfaces with alternate layers CROWN AND BRIDGE PROSTHETICS of incisal material up to the canine. Precure the individual layers with the Quick curing light. Finally, complete the incisal edge using Incisal Edge material and precure. 57

58 PALATAL LAYERING Cover the palatal fossa with Occlusal Dentin. Complete the pontic and marginal ridges with Dentin. Build up the marginal ridges and tubercle with Transpa and slightly coat with Opal Effect 3 and 4. PREPARING THE RESTORATION FOR POLYMERIZATION/ TEMPERING It is indispensable to observe the following steps when preparing metal-supported SR Adoro restorations to be polymerized/tempered: Step 1- Applying SR Gel After the layering procedure has been completed, all layers must be precured. To make sure that this is the case, the individual segments may be precured for 20 seconds one more time. Apply SR Gel on the entire veneering surface in a fully covering yet not inappropriately thick coat to prevent an inhibition layer. If necessary, precure again and apply SR Gel. 58

59 Step 2 Applying SR Adoro Thermo Guard After applying SR Gel, cover all exposed metal parts with SR Adoro Thermo Guard. Open SR Adoro Thermo Guard syringes only immediately before use to prevent admission of air. Rapidly fill up first the internal aspects, or basal surfaces, of the crown and then cover exposed metal parts, such as scallops, occlusal surfaces and margins and smooth out SR Adoro Thermo Guard. Ensure that the material is applied in a homogenous layer and wets the metal surfaces thoroughly. Avoid large amounts of SR Adoro Thermo Guard on veneering surfaces. Re-seal the syringe immediately after application, mount the restoration on the object holder and polymerize/temper in the Lumamat 100 or Targis Power Upgrade furnace. Version A Application of SR Adoro Thermo Guard to full-coverage veneer Version B Application of SR Adoro Thermo Guard to partial veneer CROWN AND BRIDGE PROSTHETICS Cover exposed metal portions and palatal surfaces. Ensure thorough wetting and smooth out SR Adoro Thermo Guard. After application of SR Adoro Thermo Guard, mount restoration on the object holder. Apply SR Adoro Thermo Guard only immediately before carrying out the polymerization/tempering procedure in the furnace. Once applied, the paste must not be left to dry unnecessarily. 59

60 POLYMERIZATION/ TEMPERING After application of SR Gel and SR Adoro Thermo Guard, mount the restoration on the object holder and place it in the Lumamat 100 or Targis Power Upgrade furnace. Observe the following points when carrying out the polymerization/ tempering procedure: Basically, the following rule applies: The smaller the amount of material in the furnace, the more controlled the polymerization/tempering process will be. 2 programs (P1 and P3) are available for tempering metal-free and metal-supported restorations. Metal-free single restorations are polymerized/tempered without the model. Metal-free restorations (3-unit bridges) can be polymerized/tempered on the model. All removable parts of the model (pontic inserts, neighbouring teeth) have to be removed from the model. The remaining weight of the working model must not exceed 400 g (this weight corresponds to the weight of a large working model incl. split cast base). Always polymerize/temper metal-supported restorations without the model. Ensure slow cooling to room temperature after completion of the polymerization/tempering process. Lumamat 100 / Targis Power Upgrade Metal-supported Metal-free Program 1 3-unit bridges on model with detachable segments 4 or more inlays, onlays and/or crowns on dies Program 3 crowns with SR Adoro Thermo Guard bridges with SR Adoro Thermo Guard 3 or less inlays, onlays and/or crowns on the dies Mount the restoration without the model on the object holder Final polymerization/tempering of dentin / incisal layering Apparatus Time Program Curing time per segment Quick 20 sec. Polymerization/ tempering Lumamat 100/ Targis Power Upgrade 25 min. 3 select program 3 and press start. Calibrate the furnace on a regular basis by means of the L100 test set. Observe the corresponding manufacturer s instructions. 60

61 FINISHING After completion of the polymerization/tempering procedure, completely remove SR Gel and SR Adoro Thermo Guard from the restoration using running water and/or steam blaster. Complete restoration with cross-cut tungsten carbide burs, fine diamonds and flexible discs. It is advisable to use a low rpm and light pressure. Make sure to remove the inhibition layer of approx. 30 µm from all surfaces of the restoration. Fit the restoration to the model and adjust proximal and occlusal contact areas. Subsequently, establish a lifelike outline and surface structure, including growth lines and convex/concave areas. CROWN AND BRIDGE PROSTHETICS Remove SR Gel and SR Adoro Thermo Guard. Establish contact points and mount the restoration on the model. Remove inhibition layer with cross-cut burs and discs... and establish to a lifelike outline and surface structure. 61

62 POLISHING Prepolishing Smooth the surfaces (convex areas) of the natural structure and the marginal ridges with rubber polishers and silicone polishing wheels in order that these areas will have a higher surface gloss after high-gloss polishing. Silicone polishing wheels can also be used to polish metal-composite interfaces. Use commercially available polishers, such as rubber polishers and silicone polishing wheels to polish the convex areas and metal-composite interface. Ideal silky mat gloss after prepolishing. 62

63 High gloss polishing The restorations are polished to a high gloss using a goat s hair brush, a cotton and/or leather buff and Universal polishing paste. Use a low rpm and light pressure to polish the restorations to a high gloss; do not use a polishing lathe. It is advisable to turn a goat s hair brush into a star shape to polish the interdental space and occlusal surfaces effectively. The smaller contact surfaces of the star-type brush permit targeted polishing of the areas as desired. Depending on the level of surface gloss to be achieved, either a cotton buff (lower gloss) or a leather buff (higher gloss) is used. CROWN AND BRIDGE PROSTHETICS Use Universal polishing paste, an ordinary goat s hair brush and a modified goat s hair brush to polish the surfaces. Light gloss after polishing. Use a cotton buff to polish to a high gloss. Microroughness on the surfaces of finished veneers is conducive to plaque accumulation. Polish carefully. Pay particular attention to crown margins, interdental spaces, occlusal surfaces, and basal contact surface of pontics. 63

64 THE RESULT Homogenous surface with true-to-nature colour effect and enamel-like high-gloss finish. The lifelike opalescent effect imparts a highly aesthetic appearance to the restoration. 64

66 APPLICATION PROCEDURE FOR SR ADORO IN COMBINATION DENTURES In the fabrication of combined dentures, composite veneers are the material of choice. Different application procedures are required, depending on the type of polymerization process used. SR Adoro veneers can be fabricated in two different ways and can therefore match various working procedures in the dental laboratory. Ivoclar Vivadent recommends users to apply method a as this method prevents the denture saddle from being exposed to excessively high temperatures. Version A: Veneering with SR Adoro BEFORE setting up and completing the denture saddles Version B: Veneering with SR Adoro AFTER setting up and completing the denture saddles 1. Fabricate primary and secondary parts (e.g. telescope crowns) 2. Fabricate the model casting (transversal connector, sublingual saddle bar) 3. Join the secondary parts with the model casting by adhesive joining, soldering or lasering technique 4. Veneer the secondary parts with SR Adoro 5. Polymerize/temper, finish and polish the SR Adoro veneer 6. Mask the retention components of the model casting with SR Adoro Opaquer pink 7. Set up and complete the denture with denture base material (e.g. ProBase Cold/Hot) 1. Fabricate the primary and secondary parts (e.g. telescope crowns) 2. Fabricate the model casting (e.g. transversal connector, sublingual saddle bar) 3. Connect the secondary parts with the model casting using a joining technique (adhesive joining), soldering or lasering 4. Mask retention components of the model casting with SR Adoro Gingiva Opaquer pink 5. Set up and complete the combination denture 6. Veneer secondary parts with SR Adoro 7. Completely cover the denture saddles and teeth with SR Adoro Thermo Guard, as a high temperature of 104 C is used to conduct the polymerization/ tempering cycle. All composite areas must be completely covered. 8. Polymerize/temper, finish and polish the SR Adoro veneer 66

67 SHADE MATCHING OF SR ADORO TO DENTURE TEETH Matching the shade of the composite veneers to the denture teeth plays a crucial role in combination dentures. SR Adoro and the specifically developed Neck material enable efficient shade matching. Chromascop shade guide (in conjunction with SR Antaris, SR Postaris denture teeth) Deep Dentin / Dentin / Incisal layering The individual SR Adoro pastes are applied according to the layering diagram for the Chromascop shade guide. Firmly adapt (press into place) the first layer to achieve a reliable bond between the composite and opaquer surface. Precure each segment for 20 seconds, using the Quick light unit. In the cervical area, build up Deep Dentin in a half-moon shape to stabilize the shade. Create smooth and rounded transitions between the individual layers (Deep Dentin Dentin Incisal), using the SR modelling instruments and synthetic brushes. After that, build up the dentin materials layer by layer and precure each segment for 20 seconds. Design the dentin core in such a way that the shape of the mamelons are still visible in the dentin. Provide enough space for the subsequent layering of Incisal and Transparent materials. Next, complete the restoration layer by layer using the corresponding Incisal materials. Precure the individual layers for 20 seconds per segment, using a Quick light unit. COMBINATION DENTURES The basic working procedures (modeling, casting, divesting/separating, framework conditioning, opaquing) and removal of the inhibition layer are carried out as described on pages for the fabrication of crown and bridge restorations. 67

68 SR Vivodent PE shade guide (in conjunction with SR Vivodent PE, SR Orthotyp PE denture teeth) Neck / Dentin / Incisal layering The individual SR Adoro pastes are applied according to the layering diagram of the PE shade guide. Firmly adapt (press into place) the first layer to achieve a reliable bond between the composite and opaquer surface. Precure each segment for 20 seconds using the Quick light unit. Apply Neck material in a half-moon and spread out to a thin layer using SR modelling instruments and synthetic brushes. The Neck material is not covered with Dentin. Next, build up the Dentin materials layer by layer. Create the dentin core in such a way that the shape of the mamelon is still visible in the dentin. Make sure that the marginal ridges in the dentin are positioned slightly more to the back compared to the Chromascop layering method. Subsequently, complete the restoration layer by layer using the corresponding Incisal material. Precure the individual layers for 20 seconds per segment using the Quick curing light. The basic working procedures (modeling, casting, divesting/separating, framework conditioning, opaquing) and removal of the inhibition layer are carried out as described on pages for the fabrication of crown and bridge restorations. 68

69 MASKING OF MODEL CASTING RETENTIONS WITH GINGIVA OPAQUER Conditioning with SR Link After having completed the model casting, carefully blast the retentions with type 100 Al2O3 at 3 bar pressure (see page 32 and the corresponding alloy manufacturer s instructions). Blasting enhances mechanical retention. Blasting roughens and enlarges the surface. After blasting, remove residue from the framework by tapping it off; do not remove residue with steam or an air gun. Apply SR Link immediately after having tapped off residue. Use a clean disposable brush to apply SR Link. Allow the material to react for 3 minutes. Do not soak metal surfaces with SR Link. Carefully blast the retentions with type 100 Al2O3 at 3 bar pressure. Remove residue by tapping it off with an instrument. Apply SR Link immediately after blasting and allow to react for 3 minutes. When using SR Link, do NOT use an air gun OR steam to clean the framework after blasting. Avoid touching the surfaces after blasting. COMBINATION DENTURES 69

Polymerize in a Lumamat 100 or Targis Power Upgrade furnace using program 2. Apply a fully covering 2 nd opaquer layer and precure each segment for 20 seconds. Polymerization is carried out without the model, using program 2. When positioning the model castings on the object holder, make sure that enough light can reach them (avoid shadow casting). After completion of the polymerization procedure, check the curing depth with a probe. If necessary, repeat the polymerization cycle. Preparing the restorations for finishing After completion of the polymerization process, check the curing depth with a probe. Then, remove the inhibition layer using the monomer of the denture base material and disposable brushes. This measure is necessary to prevent the formation of streaks. Make sure that the opaquer exhibits a silky mat surface. The monomers of cold-curing denture base materials, such as ProBase Cold, are best suited for removing the inhibition layer.

Block out undercuts with blocking out wax or block out resin to ensure that the restoration can be removed from the die without being damaged after the polymerization process. It is advisable to apply a sealer to harden the surface and to protect the stone die from abrasion. The application of the sealer must not cause any changes in the dimension of the stone die. It is not mandatory to utilize a spacer, as two coats of SR Model Separator will be applied. If you use a spacer, check as to whether it is compatible with SR Model Separator. INLAYS / ONLAYS A model with a detachable die is used as the basis. The die is coated with sealer. Sealing the dies and adjoining parts of the model SR Model Separator is applied in two thin coats. Apply the first layer slightly more generously than the second one and make sure to fully cover all areas of the cavity. Watch out for sharp edges in particular. Allow the first layer to react for 3 minutes. Subsequently, apply the second layer of SR Model Separator in a thin coating, invert the model and allow to dry for 3 minutes. Additionally, apply SR Model Separator to adjoining model surfaces that may come into contact with SR Adoro (incl. counterbite), allow to react for a short time and then disperse excess material with oil-free compressed air. Apply first coat of SR Model Separator generously, watch out for sharp edges and allow to react for 3 minutes. Apply second layer of SR Model Separator in a thin coating and allow to dry for 3 minutes in an upside down position. 77

78 Applying the liner Application technique in cavities without discoloration Application technique in cavities with slight discoloration Application technique in cavities with severe discoloration Apply Liner clear to the cavity walls and the cavity floor (dentin surface) for an optimal chameleon effect. Apply Liner incisal along the marginal areas (course of natural enamel) to achieve a harmonious transition between the shade of the restoration and natural tooth structure without grey lines. Mask dark areas using a liner in an appropriate shade ( ). Coat the remaining portions of the cavity, except the marginal areas, using Liner clear.

Liner clear Liner incisal Liner Application of first coating of liner: , clear Extrude the desired amount of the ready-to-use, paste-type liner from the syringe and spread it out slightly on the mixing pad, using a disposable brush. First, apply the liner in question to the cavity walls and cavity floor in a thin coat and precure each segment for 20 seconds, using a Quick curing light. Make sure to fully cover all areas, as the liner provides an essential bonding surface to the luting composite. Do not cover marginal areas at this stage (course of natural enamel). Fully cover the cavity walls and cavity floor with the first coating of liner. Precure each segment for 20 seconds, using a Quick curing light. 78

79 Application of second coating of liner: incisal Following the application of the first coating, apply Liner incisal to the marginal areas, so that finally all cavity surfaces are covered with liner. Apply liner incisal to a level with the preparation margins to ensure a reliable bond between the margins and the luting composite.

The layer thickness should be at least 150 µm. Thin out the liner layer towards the preparation margins. Do not detach hardened SR Adoro Liner from the die, as the layer may become deformed or break in the process. If desired, the translucency of the liners may be increased by using Liner clear or Liner incisal. Removing the inhibition layer Thoroughly remove the resulting inhibition layer using a disposable sponge (do not use solvent); make sure that the liner surfaces are free of residue and exhibit a mat finish. Thoroughly remove the inhibition layer using clean disposable sponges. 79

80 INLAY / ONLAY LAYERING Adapt the first layer firmly (press it into place) to ensure an effective bond between the liner and composite and precure each segment for 20 seconds using the Quick curing light. The shade effect in the interdental space and cavity may be increased by means of Occlusal Dentin orange. Slightly emphasize the marginal ridges and cusps with Deep Dentin. Subsequently, begin the process of building up the cavity with Dentin materials; make sure to provide adequate space for the subsequent application of Incisal and Transpa materials. The translucency of the restoration may be increased by means of coloured Transpa materials, such as Transpa orange-grey and Transpa brown-grey. Build up the SR Adoro layering materials layer by layer; make sure to precure each individual layer. After building up and precuring the dentin plateau, apply characterizations with SR Adoro Stains and precure for 20 seconds. Next, complete the restoration using Incisal and Transpa materials. The cusp tips and triangular ridges may be supplemented with a fine layer of Opal Effect 3 and 4. Adapt firmly and create smooth rounded transitions between the layers using SR modelling instruments and synthetic brushes. Increase the shade effect in the interdental space and cavity area with Occlusal Dentin and slightly emphasize the marginal ridges and cusps. Build up a plateau using various Dentin materials 80

Precure with the Quick curing light and apply Incisal and transparent materials to cover the characterizations; create a true-to-nature occlusal morphology. Complete the procedure by precuring each section for 20 seconds using the Quick curing light. It is essential to observe the stipulated curing depths and maximum layer thickness of the individual materials when carrying out the layering procedure. If the maximum layer thickness is exceeded, break up large portions into several increments and precure each increment for 20 seconds. Always overcoat SR Adoro Stains with layering material (e.g. Incisal, Transpa). 81

82 PREPARING THE RESTORATION FOR POLYMERIZATION/ TEMPERING After the layering procedure has been completed, all layers must be precured. To make sure that this is the case, the individual segments may be precured for 20 seconds one more time. Next, apply SR Gel on the entire veneering surface ensuring that all areas are fully covered and the layer is not too thick. If necessary, precure one more time and apply a fully covering but not inappropriately thick coat of SR Gel. POLYMERIZATION/ TEMPERING After application of SR Gel, mount the restoration on the object holder and place it in the Lumamat 100 or Targis Power Upgrade furnace. Make sure to position the restoration correctly in the furnace. Observe the following points when carrying out the polymerization/tempering procedure: Basically, the following rule applies: The smaller the amount of material in the furnace, the more controlled the polymerization/tempering process will be. 2 programs (P1 and P3) are available for polymerizing/tempering metal-free and metal-supported restorations. Metal-free single restorations are polymerized/tempered without the model. Metal-free restorations (3-unit bridges) can be polymerized/tempered on the model. All removable parts of the model (pontic inserts, neighbouring teeth) have to be removed from the model.

84 FINISHING After completion of the polymerization/tempering procedure, completely remove SR Gel from the restoration using running water and/or a steam blaster. Carefully remove the restoration from the die, while it is still warm. If the restoration is removed at a later stage, it is advisable to warm up the stone die by means of water vapor. Finish the restoration with crosscut tungsten carbide burs and fine diamonds. It is advisable to use a slow rotational speed and light pressure. Make sure to rework the entire restoration to remove the inhibition layer of approx. 30 µm from all surfaces. Carefully taper the margins of the restorations, lightly grind the margins and adjust proximal and occlusal contact points. Subsequently, recreate a lifelike tooth shape and surface structure. Remove SR Gel and carefully remove the restoration from the die. Remove inhibition layer using cross-cut burs and discs. Lightly grind the margins using fine diamonds and tungsten carbide burs and recreate a true-to-nature surface structure. 84

85 POLISHING Prepolishing Carefully smooth the ridges of the occlusal surface and proximal surfaces with rubber polishers and silicone polishing wheels. Pay particular attention to the margins in order to avoid rendering them too short. INLAYS / ONLAYS High gloss polishing The restorations are polished to a high gloss using a goat s hair brush, a cotton and/or leather buff and Universal polishing paste. Use a slow rotational speed and light pressure to polish the restorations to a high gloss; do not use a polishing lathe. It is advisable to use a goat hair brush that has been modified into a star-shaped one and a pen brush to polish the interdental space and occlusal surfaces properly. The smaller contact surfaces of the star-shaped brush permit targeted polishing of the areas as desired. Depending on the level of surface gloss to be achieved, either a cotton buff (lower gloss) or a leather buff (higher gloss) is used. SR Adoro inlay and onlay polished to a high gloss. Microroughness on the finished veneering surface is conducive to plaque accumulation. Polish carefully. Pay particular attention to margins and occlusal surfaces. PREPARING RESTORATION FOR CEMENTATION It is essential to cement metal-free SR Adoro restorations in place using the adhesive cementation technique. Carefully blast the contact surfaces of the restoration with type 100 Al2O3 at 1 bar pressure in the laboratory to provide a chemical bond to the luting composite. Following the try-in in the dental practice and subsequent cleaning, the contact surfaces are again roughened using a 25 µm finishing diamond. This step is carried out immediately before adhesive cementation. Finally, the surfaces are silanized (e.g. with Monobond S) to enable a chemical bond. 85

86 THE RESULT Homogenous surface and enamel-like high-gloss finish. The excellent chameleon effect and lifelike opalescence impart a highly aesthetic appearance to the restoration. 86

87 ANTERIOR CROWNS SR Adoro ANTERIOR CROWNS 87

88 ANTERIOR CROWNS Starting situation Fabricate a master model or a model with detachable segments on the basis of the impression in the usual manner. Expose and mark the preparation margin. Block out undercuts with blocking out wax or block out resin to ensure that the restoration can be removed from the die without being damaged after the polymerization/tempering process. It is advisable to apply a sealer to harden the surface and to protect the stone die from abrasion. The application of the sealer must not cause any changes in the dimension of the stone die. It is not necessary to use a spacer, as two coats of SR Model Separator will be applied. If you use a spacer, check as to whether the material is compatible with SR Model Separator. A master model is used as the basis. The detachable die is coated with sealer. Sealing the die and adjoining parts of the model SR Model Separator is applied in two thin coats. Apply the first layer slightly more generously than the second one and make sure to fully cover all areas of the die. Watch out for sharp edges (incisal edges) in particular. Allow the first layer to react for 3 minutes. Subsequently, apply the second layer of SR Model Separator in a thin coating, invert the die and allow it to dry for 3 minutes. Additionally, apply SR Model Separator to adjoining model surfaces that may come into contact with SR Adoro (incl. counterbite), allow to react for a short time and then disperse excess material with oil-free compressed air. Apply first coat of SR Model Separator generously, watch out for incisal edges and allow to react for 3 minutes. Apply second layer of SR Model Separator in a thin coating and allow to react for 3 minutes in an upside down position. Coat adjoining parts of the model, such as neighbouring teeth and counterbite, with SR Model Separator. 88

89 Applying the liner Extrude the desired amount of the ready-to-use, paste-type liner from the syringe and spread it out slightly on the mixing pad, using a disposable brush. First, apply the liner in question to the surfaces of the die in a thin coat. Make sure to fully cover all areas, as the liner forms an essential bond to the luting surface. The liner must be applied in a layer thickness of at least 150 µm. Precure each segment for 20 seconds using the Quick curing light. ANTERIOR CROWNS Fully cover the entire surface of the die with a minimum layer thickness of 150 µm. TIP Liner incisal may be applied to the marginal area to facilitate the transmission of light in the cervical region. This measure provides a harmonious transition between the gingiva and restoration. Application procedure in non-vital dies Mask the entire die with Liner 050 to block out the dark colour of the underlying tooth stratum and, at the same time, to attain an adequate degree of brightness. Additionally, Stains white or Stains crackliner may be applied locally to the liner surface to further increase the degree of brightness. Polymerizing the liner Apparatus Time Program Precuring time per segment Quick 20 sec. Polymerization Lumamat 100/ Targis Power Upgrade Precure each segment for 20 seconds using the Quick curing light. The entire inner surface of the restoration has to be covered with SR Adoro Liner. The layer thickness should be at least 150 µm. Thin out the liner layer towards the preparation margins. Do not detach hardened SR Adoro Liner from the die, as the layer may become deformed or break in the process. If desired, the translucency of the liners may be increased by using Liner clear or Liner incisal. Removing the inhibition layer Thoroughly remove the resulting inhibition layer using a disposable sponge (do not use solvent); make sure that the liner surfaces are free of residue and exhibit a mat finish. 89

90 ANTERIOR LAYERING Adapt the first layer firmly (press it into place) to ensure an effective bond between the liner and composite and precure each segment for 20 seconds using the Quick curing light. The shade effect in the interdental space and palatal fossa may be increased by means of Occlusal Dentin orange. Build up the labial face using various Dentin materials. Reproduce areas of higher brightness with Opal Effect 3 (cervical) and Inter Incisal white-blue (incisal). Apply the appropriate Transpa materials to the dentin core. Build up and precure the incisal extension using Opal Effect materials (OE 1 and OE 2). Mimic mamelons using Mamelon materials and Stains and precure. Next, complete the restoration by applying Incisal and Transparent materials layer by layer. Build up the palatal ridges using Dentin material. These ridges and the triangular ridges may be overcoated with a fine layer of Opal Effect 3 and 4. Adapt firmly and create smooth rounded transitions between the layers using SR modelling instruments and synthetic brushes. Complete marginal areas with Deep Dentin and Dentin; enhance the shade effect in the palatal region by means of Stains and Occlusal Dentin and precure for 20 seconds using the Quick curing light. Complete the dentin core with Transpa materials and build up the incisal area using Opal Effect 1. 90

91 Reproduce mamelons using Mamelon materials and Stains and precure. Complete the tooth shape using Incisal materials. ANTERIOR CROWNS Mimic enamel cracks between the lateral segmentation using Stains crackliner; complete the labial and palatal tooth shape using Incisal and Transpa materials and precure for 20 seconds, using the Quick curing light. It is essential to observe the stipulated curing depths and maximum layer thickness of the individual materials when carrying out the layering procedure. If the maximum layer thickness is exceeded, break up large portions into several increments and precure each increment for 20 seconds. 91

92 PREPARING THE RESTORATION FOR POLYMERIZATION/ TEMPERING After the layering procedure has been completed, all layers must be precured. Apply SR Gel on the entire veneering surface ensuring that all areas are fully covered and the layer is not too thick. Mount the restoration with the die on the object holder. Apply a fully covering but not inappropriately thick coat of SR Gel to the restoration... and mount it on the object holder. POLYMERIZATION/ TEMPERING After application of SR Gel, mount the restoration on the object holder and place it in a Lumamat 100 or Targis Power Upgrade furnace. Observe the following points when carrying out the polymerization/tempering procedure: Basically, the following rule applies: The smaller the amount of material in the furnace, the more controlled the polymerization/tempering process will be. 2 programs (P1 and P3) are available for polymerizing/tempering metal-free and metal-supported restorations. Metal-free single restorations are polymerized/tempered without the model. Metal-free restorations (3-unit bridges) can be polymerized/tempered on the model. All removable parts of the model (pontic inserts, neighbouring teeth) have to be removed from the model. The remaining weight of the working model must not exceed 400 g (this weight corresponds to the weight of a large working model incl. split cast base).

93 FINISHING AND POLISHING Finishing After completion of the polymerization/tempering procedure, completely remove SR Gel from the restoration using running water and/or a steam blaster. Carefully remove the restoration from the die, while it is still warm. If the restoration is removed at a later stage, it is advisable to warm up the stone die by means of water vapor. Finish the restoration with crosscut tungsten carbide burs and fine diamonds. It is advisable to use a slow rotational speed and light pressure. Make sure to rework the entire restoration to remove the inhibition layer of approx. 30 µm from all surfaces. Carefully taper the margins of the restorations, grind them lightly and adjust proximal and occlusal contact points. Subsequently, recreate a lifelike tooth shape and surface structure, including growth lines and a profile of convex-concave areas. Prepolishing Carefully smooth the surfaces (convex areas) of the lifelike structure and the marginal ridges with rubber polishers and silicone polishing wheels so that these areas will exhibit a higher degree of lustre after high gloss polishing. High gloss polishing The restorations are polished to a high gloss using a goat s hair brush, a cotton and/or leather buff and Universal polishing paste. Use a slow rotational speed and light pressure to polish the restorations to a high gloss; do not use a polishing lathe. It is advisable to modify a goat s hair brush into a star-shaped one to polish accentuated contours (palatal fossa) properly. The smaller contact surfaces of the star-shaped brush permit targeted polishing of the areas as desired. Depending on the degree of surface gloss to be achieved, either a cotton buff (lower gloss) or a leather buff (higher gloss) is used. ANTERIOR CROWNS SR Adoro anterior crown polished to a high gloss. Microroughness on the finished veneering surface is conducive to plaque accumulation. Polish carefully. Pay particular attention to crown margins, proximal areas and palatal surfaces. PREPARING RESTORATION FOR CEMENTATION It is essential to cement metal-free SR Adoro restorations in place using the adhesive cementation technique. Carefully blast the contact surfaces of the restoration with type 100 Al2O3 at 1 bar pressure in the laboratory to provide a chemical bond to the luting composite. Following the try-in in the dental practice and subsequent cleaning, the contact surfaces are again roughened using a 25 µm finishing diamond. This step is carried out just before adhesive cementation. Next, the surfaces are silanized (e.g. with Monobond S) to enable a chemical bond. 93

94 THE RESULT Balanced relationship between brightness and chroma as well as lifelike enamel cracks. Enamel-like durable high-gloss finish. The true-to-nature opalescent effect imparts a highly aesthetic appearance to the restoration. 94
