Survival rate of In-Ceram restorations

This paper reports on 76 consecutively placed In-Ceram restorations (61 complete-coverage crowns and 15 fixed partial dentures). Their survival rates were determined using the Kaplan-Meier method. During the 35-month observation period no crown failures occurred, a five-unit fixed partial denture fractured, and another fixed partial denture was removed because of periodontal complications. Thus, In-Ceram complete-coverage ceramic crowns are apparently indicated for anterior and posterior teeth. A larger number of subjects must be studied to assess the indication for all-ceramic fixed partial dentures.
