2 GOLD IS FOREVER TIMELESS The trend in prosthetics towards highly aesthetic precious metal restorations continues unabated. Despite fluctuating prices, the desire to place one s trust in consistent, reliable values is as strong as ever in values such as biocompatibility, durability and aesthetics, which are immune to any short-lived trend. Because of its long-standing tradition in matters of precious metals, WIELAND has for many years taken it upon itself to offer dental labs and clinicians innovative and competitive dental alloys.

4 IN PRACTICE Renewed vitality in every light The use of ZIROX veneering ceramic on implant-borne bridges in zirconium oxide is the process of choice, not only because of its unrestricted biocompatibility but because the skilful use of ZIROX gives vibrant aesthetics accompanied by stunning light dynamics. Haristos Girinis is known to his colleagues as an attentive and accessible modern practitioner. His keen eye for the type of denture required by his patients goes far beyond the mere dictates of clinical indication. The particular desires and vision of each individual patient, together with the overall appearance, influence the choice of material and application. Girinis defines perfect aesthetics for a well-fitting permanent denture in terms of absolutely identical shade matching, translucence and a natural red / white balance. With many years experience as an expert consultant and speaker at WIELAND events, he is delighted to pass on his wealth of expertise to colleagues in training sessions and in regular contributions to WIELAND DIRECT. A special topic in this issue is the perfectly harmonized veneering of a six-unit bridge framework in zirconium oxide with ZIROX using the established 3-layer build-up technique. The patient is a 72-year old man whose new anterior bridge reflects his stunning vitality. The ZIROX veneering ceramic is suitable for veneering hard sintered all-ceramic frameworks in ZrO2 with a CTE of approx x 10-6 K -1 ( C). The framework was milled to an anatomical shape and designed to provide support at the cusps. Here you can follow a step by step account of the process used. Page 4 Issue 02/2009

5 IN PRACTICE 1. Initial situation: a 72-year old patient. 2. Fit and elegance. 3. Shoulder material applied for fluorescence. 4. Copings prepared for the ceramic build-up of the rough fluorescing surfaces 5. For the first dentine bake, high-chroma materials such as Modifier, Chromatix and Fludentine are applied. 6. Dentine layer in the approximal areas with Fludentines to illuminate the gingiva. The restoration has the characteristics of natural dentition. The translucence of the framework material and the selective build-up of the veneering ceramic seemingly breathes life into the restoration under a variety of lighting conditions, creating creates the illusion of natural vitality. 7. Photographed in reflected light after the second dentine bake. 8. Photographed in transmitted light. The surface is thoroughly sintered once the prescribed firing temperature has been reached. 9. When the build-up of the final shape is completed with incisal materials, this is followed by the third and final dentine bake. The aesthetic effect is reflected in the restored natural smile of the patient. 10. Each individual tooth receives its characteristic anatomical shape. 11. The material is given the finishing touches by manual fine grinding and buffing. 12. View after the individually modified glaze bake. 13. Manual polishing gives the final touch of brilliance. 14. The denture acts like natural dentition. Varying light effects create the impression of vitality. 15. Once inserted, the crowns blend harmoniously into the overall appearance of the oral environment. 16. The red/white balance and translucence ensure the best possible aesthetics. Issue 02/2009 Page 5

6 Innovation individual efficient perfect system compatible Adhesive bond (the same for all systems) TITANIUM BASES Titanium base to fit the implant system used An intelligent basis for zirconium oxide As a ZENOTEC user, you can now put the fabrication of implant-borne restorations on an intelligent basis: with ZENOTEC titanium bases. In times of digitisation, this ensures that value creation remains where the expertise lies. In times of innovative CAD/CAM production, a previously untapped potential for success in the laboratory is to be found at the interface between the implant and framework of high-class dentures. Until now, conventional system-dependent abutments have been used, but these are expensive to buy and time-consuming to work with. In-depth WIELAND lab tests with the ZENOTEC CAD/CAM system have now given rise to a new and impressive solution, ZENOTEC titanium bases, The integrated ZENOTEC process for implant-borne zirconium oxide frameworks > > Scan and design! Insert titanium base in model! Affix suitable scan abutment! Scan and design! Page 6 Issue 02/2009

7 Innovation which are suitable for many leading implant systems and which enable highly aesthetic abutments with emergence profiles which perfectly match the gingiva to be made in the shortest possible time. More economical then ever CAD/CAM zirconium oxide frameworks produced in this way have never been so affordable. The Fraunhofer Institute (Germany) for Mechanics of Materials IWM has tested the titanium base system consisting of scan abutment, titanium base, lab screw and fixing screw for action of force and durability and given it an unqualified positive evaluation. A perfectly coordinated process in the dental lab With the aid of the 3Shape Abutment- Designer and ZENO Cad Implant- Designer software applications, highly aesthetic results with optimized emergence profiles can easily be obtained. Since the scan abutments have been reduced to just four sizes, the software can identify the axial direction of the implant and the position of the anti-locking grooves. Suitable abutment design software applications make it an easy matter to design the individual abutment once the model has been scanned. The ZENOTEC titanium bases are therefore a further step towards process integrated CAD/CAM fabrication of highly aesthetic and equally economical prosthetics in the dental lab. Both abutment and superstructure can be designed in a single process and milled at the same time by ZENOTEC. The titanium bases are available to match the implant systems of leading manufacturers.

8 IN PRACTICE Overpressing of zirconium oxide frameworks: the simply lucrative alternative to foreign-made Opinions differ on this issue. Master Dental Technician Frank Wüstefeld describes his personal experience with a technology about which the reactions of colleagues range from ardent support to total dismissal. The overpress technique has been available for zirconium oxide restorations for quite a few years now, but dental technicians disagree about the economic benefits for the lab. As far as my own business is concerned, I can reveal the answer. Overpressing is a lucrative process when the crowns or bridges are made using CAO (Computer Aided Overpress) technology. If the technician has to wax up the zirconium oxide framework, then the time and effort is almost the same as building up a veneering ceramic. The procedure is not worthwhile, but the combination of zirconium oxide frameworks and anatomic overpressing in milled wax or acrylic is a different matter altogether. There are currently two software applications in use with the ZENOTEC system. One is WIELAND s own ZENO Cad software, with which it is already possible to make overpressed bridges. Here individual overpress crowns and pontics are fabricated which are then be bonded to the zirconium oxide framework. As from the winter of 2009, it will be possible to mill the overpress parts either as single or splinted bridge components. Zirconium oxide frameworks with anatomic overpressing in ZENO Wax Patients can rest assured: aesthetic and affordable dentures can be made in Germany. The second software application is from 3Shape. With the current version of this program it is already possible to make CAO crowns. The 2009 release, the Beta version of which we are currently using, also enables overpress bridges to be made. The 3Shape process offers overpress design in a single piece, so that it is not necessary to bond the individual parts together. This software should be available from autumn Page 8 Issue 02/2009

9 IN PRACTICE WIELAND ZENO Cad 4.0: planning and designing CAO crowns An innovative feature of the muffle is that the cylinders can be moved separately on the base plate. This enables bridges to be made in any required shape. Because of certain unsuitable arch shapes, the size is limited to six-unit bridges. It is also possible to carry out overpressing in five different shades. This means that up to five different colours and up to 20 g of press ceramic can be pressed in the XXL muffle. The XXL muffle can only be used with the Press-i-Dent furnace from Dekema because this furnace presses the muffle against the furnace door. It does not matter how the plunger formers are distributed. 3Shape Software: planning an eight-unit overpress bridge Designing the framework is one thing, but the muffle system is just as important when it comes to obtaining reliable and reproducible results. Here it is especially important for the press cylinder to be adjustable to the work and not vice versa, as is often the case with muffle systems. The XXL muffle is made of hard plastic with fixing rings in aluminium. A sophisticated system with three muffles for 100 g, 200 g and the pear-shaped XXL 380 g size. The durable and long-lasting material makes this muffle a sound investment for many years to come. Easy to clean and wear-free. A perfect blend of craftsmanship and automation The WIELAND Press X Zr press ceramic is the perfect match for the ZENO Zr material. The transparent blanks are available in six different degrees of brightness and translucence. After pressing, the sprues are trimmed off and ground. Then the surface is textured and colouring can begin. For this, the new Body Stains are used. These create the right shade with even greater ease and speed. Finally, the glaze bake is carried out. This, too, is a WIELAND innovation. Glaze materials that can be sprayed from a can. Economical, fast, clean and always evenly applied. The flexibility of up to five individually positionable plunger formers Overpressing in size XXL with the PressX Muffle Aesthetic, fast and economical: CAO overpressed bridges There are only a few stages which need to be done by hand. Whilst this fact will not delight every technician, there is no way to banish automation from the lab in the long term. As highperformance automatic systems such as ZENOTEC T1 come onto the market, accompanied by ever more sophisticated tools, the quality of the dental surfaces obtainable improves considerably. But there is a positive aspect to this, too. As machine output increases, it becomes more and more difficult for suppliers from abroad because dentures can be produced just as economically in Germany. Issue 02/2009 Page 9

10 Structure WIELAND creates organisational structures to pave the way for future growth Torsten Schwafert is the new executive in charge of the Dental Division. Since the beginning of August, the Dental and Industry Divisions have become independent of each other. Torsten Schwafert, since August 1 st 2009 the executive responsible for WIELAND s Dental Division. Focusing on customers and markets WIELAND Dental + Technik GmbH & Co. KG, a major supplier of dental system solutions as well as precious metals, materials and semi-finished products for industrial applications, is adapting its organisational structures to better cater for the needs of the market. The rapid technological developments of recent years have increasingly led to the Dental and Industry Divisions setting different strategic priorities. Whereas alloys, electroforming and precious metal recovery were previously core business areas at WIELAND, today the areas of all-ceramic restorations and CAD/CAM are playing an ever more important part. On the other hand, the Industry Division is increasingly making its mark through innovative products in the sectors of solar energy, electrical engineering and medical devices. New management for the Industry Division In order to do justice to these developments, Oliver Völlinger (44) will in future be concentrating, in his role as member of the executive management, exclusively on the Industry Division in order to develop this sector still further and attain sustainable growth for WIELAND in this area. New management for the Dental Division On August 1 st 2009, Torsten Schwafert (44), previously Head of Sales and Marketing at DeguDent, assumed responsibility for the Dental Division. His operative remit includes the areas of R & D, sales and all aspects of CAD/CAM technology. After training as an industrial manager and subsequently studying business administration, Torsten Schwafert held a number of senior positions in the areas of sales and marketing as well as in corporate management, for example on the management board of the Dutch company Elephant Dental B.V. In over 20 years service to the dental industry, he has been responsible for the successful introduction of many new technologies to the dental market. Continuity of experience and expertise In addition, Reinhold Brommer (56) will remain in his post as member of the management team within the Dental Division and continue to contribute his many years of WIELAND experience. Central coordination The two operative divisions of WIELAND, Dental and Industry, are centrally aligned to the interdisciplinary area of Finance and Administration, which will be headed by Friedrich Karle (52), previously Business Manager, who will in future take on the role of CFO. Mr Karle is a business graduate with 25 years experience in managerial positions in international companies. Page 10 Issue 02/2009

12 in practice X-Type ZIROX NR tray systems Future-oriented ceramic systems Since August 1 st 2009, Master Dental Technician Ernst A. Hegenbarth has been part of the successful WIELAND ceramics team. The WIELAND X-Type NR systems are based on the intuitive, innovative and dynamic shade harmony system of the Creative Circle developed by Ernst A. Hegenbarth. Ernst A. Hegenbarth, with a long-standing reputation both as a knowledgeable and eloquent speaker at dental conferences and known for his numerous publications, has decided to team up with WIELAND. He was recently the driving force behind the development of the NobelRondo systems at Nobel Biocare. This line of ceramic materials for the veneering of aluminium oxide and zirconium oxide frameworks was manufactured by Wieland Dental Ceramics. Nobel Biocare has now resolved to discontinue the NobelRondo concept, but users can rest assured: Wieland will be continuing with this successful concept by incorporating it into the X-Type range of ceramics. On September 1 st 2009 the existing ZIROX product line was expanded by the addition of the ZIROX NR shade scheme which is 100 % compatible with this tray system. In future, Mr Hegenbarth will be assisting WIELAND by contributing his vast experience in the areas of ceramics and CAD/CAM. Stay tuned for further developments. For many years, the WIELAND X-Type have been the preferred veneering ceramics of dental labs worldwide. Page 12 Issue 02/2009

13 in practice Years of investment in the development of materials expertise that is second to none and cooperating in matters of design with dental technicians such as E. A. Hegenbarth have laid the foundations for a sophisticated range of models and the very best in manufacturing quality. Our manufacturing facilities at locations in Germany set such high standards that other suppliers such as Nobel Biocare also make their NobelRondo ceramics here. As a user of ZIROX NR ceramics, you, too, can rely on a truly leading standard which will benefit your customers in terms of patient comfort, aesthetics and durability. Extremely smooth, homogeneous surfaces thanks to the HDAM microstructure Aesthetic, reproducible shade matching, light dynamics and natural colour effects Exceptionally good bonding and high strength Extremely easy to handle and offering reliable shade reproduction using the classic 3-layer build-up (opaque (liner) dentine incisal) Using X-Type veneering ceramics gives ideal physical properties and covers a broad range of indications.

This also applies to the area of veneering ceramics. An example of this is provided by the addition of the new HITEX NF paste opaque, specifically designed to meet the requirements of HITEX users. However, field trials revealed that the established HITEX paste opaques also have many supporters. In accordance with the veneering preferences of our ceramics customers, WIELAND will therefore be retaining both paste opaques. We will therefore be keeping a close eye on developments to see whether the traditional or the new somewhat more fluid formula of this paste opaque will prevail. Issue 02/2009 Page 13
