The Pre-Sintered Zirconia Kit was developed in collaboration with Dr. Dan Butterman, DDS, and is used for processing and polishing Pre-Sintered Zirconia. The included carbide instruments allow the surface to be optimally prepared and processed, while the included 2-step diamond impregnated polishing system leaves a perfect finish on zirconia. The MEISINGER Twist polishers, which have already won several awards, round off the kit perfectly. With this combination put together by Dr. Dan Butterman, DDS, the user has all the important instruments for extra oral processing of zirconia.
