Masterfully crafted ceramic restoration:
Focus on precision and a natural appearance.
At the dental laboratory, the main focus is on precision, attention to detail and great craftsmanship. In many cases, everything in this world revolves around (all-) ceramic material. The art of mastering this fine material is at the heart of all dental work. Whether after pressing, CAD/CAM milling and grinding or veneering – it is the finishing of the surfaces that gives the restoration its unique natural look.
The key lies in introducing a natural morphology; an interplay of micro-relief and macro-textures. Ceramics are sensitive and should be processed with care and suitable tools. Monolithic zirconia, pressed lithium disilicate crowns, veneers made of glass or feldspar ceramic, crowns made of hybrid ceramic or veneered anterior bridges – Komet has the right solution for every application.
Ceramic cutters: A brilliant performance for perfect trimming of zirconia.
The brilliant white color of Komet’s ceramic burs makes these instruments look elegant and sophisticated. The K261GSQ ceramic cutter is ideal for finishing pre-sintered zirconia. The bur glides smoothly and free of vibrations across the sensitive material which makes it easier, for example, to remove objects from the blank after milling.
A special polisher is available for processing zirconia before sintering. Thanks to a two-zone working part and a special geometry, it enables gentle, efficient processing of the fragile pre-sintered material.

DCB abrasives: efficiency and flexibility for professional processing of all ceramics
Finishing a framework can be made considerably easier with DCB abrasives. The DCB abrasives (intended for use with a handpiece) impress with their effectiveness and flexibility and are suitable for all framework and veneering ceramics.
Work with these abrasives feels soft and smooth, and they allow the surfaces processed and polished with ease. DCB burs are sintered and interspersed with diamond grit and provided with a special ceramic bond (DCB = Diamond Ceramic Bond). Thanks to their high initial sharpness, even high-strength all-ceramic materials can be finished without pressure.
The yellow DCB abrasives are used for rough finishing, whereas green DCB abrasives are ideal for fine finishing. The abrasives are available in a wide variety of geometries, shapes and sizes, e.g. lens, wheel, pointed or cone.
ZR abrasives: delicate precision work and long-lasting performance for perfect ceramic restorations
The ZR abrasives (used in the laboratory turbine with water cooling) are indicated for the final shaping of the ceramic restoration. Available in three different grit sizes – coarse, normal and fine –, the diamond-coated abrasive instruments enable delicate precision work and give restorations an elegant finish.
The ZR abrasives are color-coded for easy differentiation. The shank of each bur is marked with a green and white, blue and white or red and white ring to indicate the grit size.
The special bond which permanently embeds the diamond grains ensures a long service life.
Diamond-coated ZR discs are indicated for the careful separation of frameworks or smoothing approximal areas in a targeted and gentle manner.
Tip: The ZR abrasives are available in different shapes and sizes to suit any indication. The “round” shape, for example, is particularly helpful when it comes to the precise finishing of the occlusal surface. The “inverted cone” is ideal for reworking fissures, whereas the “flame” is perfect for retouching the outer contours. The “grenade” can be used to define microtextures, such as perikymata, and the “egg” can be used to create a chamfer.
A perfect finish: Efficient and gentle polishing for unique ceramic restorations
Precise polishing of the ceramic surface is of crucial importance. A typical example: monolithic restorations (high strength). It has been shown that it is not the hardness of the ceramic that determines the abrasion behavior on the antagonist, but the surface roughness. In simple terms: the smoother the surface, the lower the abrasion.
Komet’s two-stage polishing system meets this requirement and also contributes to greater economic efficiency. The diamond polishers with a blue working part for pre-polishing and a gray working part for high-gloss polishing enable efficient polishing thanks to their smooth texture.
In addition, a three-stage polishing system is available to create a high-gloss, dense surface structure. The portfolio is supplemented by flexible polishing spirals that adapt to almost any anatomical surface. Their lamellar structure enables quick high-shine polishing of occlusal and proximal areas as well as sensitive marginal regions.
Finally, a variety of different brushes and cotton buffs are available for final polishing. These tools gently yet thoroughly polish the surface to achieve the desired finish.
