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:

  • Tip transversing blade on tungsten carbide burs to facilitate penetration of the crown material
  • Reduced heat generation thanks to effective chip spaces
  • Time savings
  • Outstanding durability

For cutting all-ceramic crowns and bridges.
