BEGO COMPETENCE IN CERAMICS Aesthetic restorations easy, customised and functional Partners in Progress
Sandra Tjarks Master Dental Technician, Product Manager BEGO Fabrication of all-ceramic restorations both customised and economical? 2
INTRODUCTION The term all-ceramics is now on everyone s lips. The demand for restorations fabricated from white, aesthetic and non-allergenic materials is coming more and more into focus. But how is it possible to meet increasing patient demands and at the same time work economically and efficiently? Which materials can be used to produce reliable, reproducible and aesthetic results, which convince the dentist and satisfy discerning patients? BEGO offers you economic, standardised and yet custom fabrication of a highly aesthetic ceramic restoration. The combination of centrally manufactured CAD/CAM frameworks and subsequent customisation by you as the dental technician is an economic alternative for every laboratory. This allows you to profit from our diverse selection of materials and expertise as a pioneer of CAD/CAM technology in the dental sector and specialist for digital processes. The best idea is to try it for yourself!

In dental technology this term is used not only for silicate ceramics but also oxide ceramics despite completely different forming techniques and physical properties. Silicate ceramic Silicate ceramic is also known as glass-ceramic. Glass is an amorphous substance, which is created when a molten material is so quickly cooled that, though crystal nuclei form during the solidification process, there is insufficient time for the crystallisation process. Chemically, glasses are classified according to the glass formers. Silicon oxide (SiO2) based glasses are used for dental restorations due to their chemical stability and the resulting high biocompatibility. With silicate ceramics, crystals (in the micro or nano range) are embedded in a glass matrix (molten glass). The coefficient of thermal expansion and strength are precisely adjusted with the aid of the type and proportion of crystals in the silicate ceramic. The crystals that produce this effect in glassceramics for dental restorations are leucite, lithium-disilicate, mica, fluorapatite and hydroxylapatite. Glass-ceramics are thus differentiated according to the type of crystals and are frequently called by that term in the daily dental routine. Dental leucite glass-ceramic is also differentiated according to the raw materials, whereby feldspar ceramic, unlike synthetic leucite ceramic, contains feldspar as source powder. Oxide ceramic Oxide ceramics have a low-glass phase or are even glass phase-free. In contrast to glass, they are not formed by melting and casting but generally by pressing ceramic powders. The units obtain their geometry and typical material properties only after subsequent sintering at high temperatures. Oxide ceramics for dental restorations consist of aluminium oxide or partially stabilised zirconia. First the porous pre-form is produced by dry pressing the source powder or slip casting and is then sintered. The subsequent contouring of the restoration is completed using CAD/CAM or copy milling. The volumetric shrinkage due to the sinter process at a later stage must always be taken into account to ensure an optimal fit of the restoration intraorally.

MATERIAL DIVERSITY Which ceramic combines first-class translucency with a great variety of shades and minimal finishing? BeCe CAD Zirkon HT+ The ultra-modern BeCe CAD Zirkon HT+ promises not only excellent aesthetic results but also has many other advantages. The high degree of translucency and the resulting increased light transmission enable a natural aesthetic appearance, which is indispensible, particularly for fully anatomical crowns and bridges. The new shade system promotes natural aesthetics. Reliable reproduction of the required tooth shade is possible with the seven shades that are now available. Two of the shades have been specially adapted to the slightly warmer, reddish A shades. Producing a marginal thickness of only 0.2 mm significantly improves the marginal geometry and considerably reduces the amount of finishing required. Indications Frameworks for partial and full veneers up to 6 units Fully anatomical crowns and bridges Dentine core crowns and bridges Primary crowns Two-pieces abutments The advantages for you Special highly translucent zirconia for natural aesthetics in the patient s mouth White aesthetics the special alternative to non-precious metal full crowns and bridges Optimised shade system with 7 shades including 2 new shades, which reproduce the slightly warmer, reddish A shades ensuring reliable reproduction of the required tooth shades Thin margins of only 0.2 mm require very little finishing Pre-stained blanks, which provide clear advantages in terms of reproducibility, time required and cost-effectiveness compared with the manual infiltration technique Perfect fit and very fine occlusal contours for easy further processing High degree of strength enables structure-conserving preparation Smooth surfaces for optimum abrasion behaviour on the opposing dentition High translucency for natural, aesthetic restorations Shade variety: BeCe CAD Zirkon HT+ is available in seven basic shades (W, RY1, RB1, RY2, RB2, RY3, RY4) 5
MATERIAL DIVERSITY Which ceramic is available, if my dentist requires a full-arch restoration? BeCe CAD Zirkon+ BeCe CAD Zirkon+ is our time-tested zirconia for fabricating single-crown to long-span bridge restorations. The milling process in the pre-sintered state and subsequent sintering in a high-temperature furnace guarantee excellent accuracy of fit and a high degree of stability. Indications Frameworks for partial and full veneers up to 16 units Fully anatomical crowns and bridges Dentine core crowns and bridges Primary crowns Two-pieces abutments The advantages for you Proven ceramic since 2008 Optimum shade system with 5 shades Pre-stained blanks, which provide clear advantages in terms of reproducibility, time required and cost-effectiveness compared with the manual infiltration technique Perfect fit BeCe CAD Zirkon+ is available in five basic shades (LL0 LL4) Long-span bridges fabricated using BeCe CAD Zirkon+: accurately fitting, stable and proven 6
MATERIAL DIVERSITY What is the ideal ceramic material for fabricating one-piece, individual abutments (as an alternative to two-pieces abutments)? BeCe CAD Zirkon XH BeCe CAD Zirkon XH is a special high-strength zirconia used for the fabrication of custom, aesthetic ceramic abutments. Indications One-piece individual abutments Two-pieces individual abutments The advantages for you Perfect white aesthetics between the implant base and framework Reliable, durable restoration thanks to excellent stability and high strength One-piece individual abutment fabricated using BeCe CAD Zirkon XH Two-pieces individual abutment fabricated using BeCe CAD Zirkon XH One-piece and two-pieces abutments available in 3 shades (LL0, LL2, LL3) Which material can also be used for fabricating highly aesthetic inlays, onlays and veneers using the CAD/CAM technique? BEGO inlays, onlays and veneers fabricated using IPS e.max CAD IPS e.max is a lithium-disilicate ceramic used for the CAD/CAM technique. Aesthetic single-unit restorations such as single and partial crowns, inlays or veneers can be expertly fabricated using IPS e.max in industrial production.

VENEERING MATERIALS / ACCESSORIES How can zirconia be safely trimmed? BeCe Air Zirkon laboratory turbine Due to its material properties zirconia reacts very sensitively to excessive heat build-up on a specific area. For this reason we recommend completing final custom trimming under water cooling. The ideal system components for trimming are the water-cooled BeCe Air Zirkon laboratory turbine and diamond rotary instruments which are specially designed for trimming zirconia e.g. the zirconia rotary instrument set for trimming flat surfaces of primary telescope crowns. All fully sintered diamond rotary instruments, which are suitable for use in a water-cooled turbine, can also be used for trimming. The advantages for you The large 2-litre water tank is unique on the market and enables efficient finishing over a long period without refilling The integrated ceramic water filter filters the dirt and dust particles from the water and prevents damage to the rotor The dampening function reduces the noise level for increased comfort and pleasant working Areas of application Water-cooled trimming of zirconia Milling telescope crowns in the Paraskop M Customisation of ceramic implant abutments Paraskop M BeCe Air Zirkon laboratory turbine Collector tray Spray guard cabin Zirconia rotary instrument set 2 12
