JOTA Zir-Prep diamonds with new and unique diamond grit and optimized bonding were specifically developed for trimming sensitive zirconia surfaces. Symmetrical alignment of diamond grit promotes less aggressive zirconia reduction at moderate surface temperatures; no risk of microcracking.

Durability is outstanding, specifically selected diamond grit guarantees extended service-life. Not only for use by dental technicians in a laboratory turbine for trimming zirconia restorations or abutments, but also by dentists for reworking or fitting restorations. JOTA Zir-Prep diamonds must be used with water cooling.
