-
Slight adaption of the ZrO₂ crown with the ZR862.FG.016
-
Quick trepanation with the round special abrasive ZR6801.FG.010/014/023.
-
For cutting adhesive bonded, all-ceramic crowns, we recommend Jackie (4ZRS). This instrument has to be applied at an angle of 45° to the crown.
-
Particularly in the case of ahesively bonded all-ceramic restorations, the separation joint should also encompass the incisal edge or the axial wall, respectively the occlusal surface in the lateral tooth area.
-
To remove the restoration, it has to be widened until it fractures. This can be performed with a lever or a Plaert crown widening pliers.
To grind down residual fragments, it is recommended to use the 4ZR.FG.012/014.
