In-vitro polishing of CAD/CAM ceramic restorations: An evaluation with SEM and confocal profilometry.

CONCLUSION: The surface roughness of ZIR, LS and FC crowns after the use of chairside polishing kits was comparable with the roughness measured before occlusal adjustment. A two-step procedure showed as good results as a three-step process. A smoother surface was obtained for ZIR and LS compared to FC with both polishing protocols.
