Influence of preparation, fitting, and cementation on the vitro performance and fracture resistance of CAD/CAM crowns.

Conclusions Retentive preparation design and/or optimal fitting reduced the number of debondings. For composite restorations, adhesive cementation should be preferred. Clinical significance Preparation design, fitting parameters as well as the type of cementation impact the performance of composite crowns. Retentive preparation design and/or good fitting are mandatory to avoid debonding of composite restorations; adhesive cementation should be preferred in any case.
