The newest addition to the team of Komet's crown cutters is Jackie™ (4ZRS), which addresses the challenge of removing adhesive-bonded, all-ceramic crowns. Optimized for use on zirconia and other high-strength ceramic materials, the Jackie crown remover (4ZRS.FG.016) is uniquely engineered to slit crowns and bridges to simplify final fracture and removal with a hand instrument. With a length of 4 mm and a tapered working end, the cutter is ideally suited for creating lingual, occlusal, and buccal separating joints, which are essential when working to remove adhesively bonded restorations. Other features and benefits include:
- Permanently bonded, high-quality diamond particles
- Densely packed diamond layer
- Outstanding durability & extended service life
- Optimal material-reduction capacity
- Extensive range of shapes and sizes to meet all needs
For cutting all-ceramic crowns and bridges.
