Resin-Bonded Fixed Partial Dentures: Ten-year Follow-up

Purpose: The aim of the study was to evaluate the survival rate of resin-bonded fixed partial dentures delivered between 1993 and 2003 in the Department of Prosthodontics of the University of Turin and in several private practices. Materials and Methods: The analysis took into consideration the following variables: preparations, metallic alloys, metal preparation and conditioning of the inner surfaces, isolation during cementation, type of cement, kind of prostheses, number of abutments, and number of missing teeth included in the prostheses. Results: The estimated survival probability for the first debonding or failure was 85% after 5 years and 71% after 10 years. Conclusions: The use of dental dam during cementation reduced the risk of debonding. No differences in survival rate were found for the other parameters.
