Crown cutter 4ZRS | JackieTM The newest additon to the team of Komet's crown cutters is JackieTM (4ZRS), which addresses the challenge of removing adhesiv-bonded, all-ceramic crowns. Optimized for use on zirconia and other high-strength ceramic materials, the JackieTM 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.
Komet's 4ZR is a cylinder-round end, coarse grit diamond used for cutting all-ceramic crowns.
