ROCK HILL, South Carolina--Dentists who place a lot of zirconia (zirconium oxide) crowns in their practice should have an instrument that cuts and removes the material efficiently.
Designed to remove zirconium-oxide restorations, the 4ZR diamond crown cutter from KOMET USA allows dentists to feel the impact by removing zirconia crowns fast and efficiently. Its name, 4ZR, plays off what it is designed for ("Fo[u]r Zirconia").
Similar to KOMET's ZR-Diamonds, the diamond particles on the 4ZR are embedded in a special bonding that leads to substance removal and long service life.
The 4ZR.314.012 is designed with a golden, stainless-steel shank and a white band making it easily identifiable. With a grit size of 125-µm, it is recommended that dentists use the 4ZR at a speed of 160,000 rpm in the red contra-angle since the higher torque is recommended for cutting zirconia.
