ZR8379L, ZR-Diamond, Egg / Football with long neck for all ceramics. Fine grit, FGL 315, size 023 (2.3mm diameter) with 4.3mm working length.

ZR-Diamonds:

Grinding of ceramic abutments, trepanation, removal or fitting of all ceramic restorations (e.g. zirconia) is very difficult to manage with conventional instruments. The instruments for all ceramic restorations were developed after comprehensive testing.

The special coating bonds the diamond grains durably into the bonding layer so that these abrasive instruments feature a considerably longer operating life and greater material reduction compared to conventional diamond instruments. The ZR-Diamonds are available in different grit sizes.

Handy Hint:

For subsequent polishing, we recommend our 2-Step polishing system for all-ceramic restorations.

We recommend 4ZRS Jack our crown cutter for cutting all-ceramic restorations (e.g. Zirconia).
