According to Frank J. Milnar, DDS, AAACD, for the best results when working with zirconia, users should rely on instruments optimized for the high-strength material.
According to Frank J. Milnar, DDS, AAACD, for the best results when working with zirconia, users should rely on instruments optimized for the high-strength material.
He says standard instruments often fail in these cases, requiring the operator to use multiple burs to adjust or polish a single restoration. In turn, if the instrumentation does not achieve a high luster on the restoration, the zirconia will be very unforgiving and antagonistic to the opposing dentition; therefore, a kit dedicated to high-strength ceramics offers the ideal solution.
Milnar says the LD0707 proprietary system from Komet USA offers the instruments necessary for adjusting occlusion and reconfiguring the luster of zirconia restorations.
In this technique video from Dr. Milnar, the case demonstrates the placement of a full-contour zirconia crown using the LD0707 Cut, Finish and Polish kit from Komet USA.
