Long‐term survival characteristics of 832 resin‐retained bridges and splints provided in a post‐graduate teaching hospital between 1978 and 1993

Abstract

The clinical performance of 832 resin-retained bridges and splints provided in the adult fixed prosthodontic clinic of a post-graduate teaching hospital was reviewed. Recall data was available for 58.4% of cases and the median survival was 7 years and 10 months. Analysis of clinical variables influencing survival revealed that the design and retainer coverage were significant factors. The experience of the operator carrying out treatment also had a pronounced effect which was not readily explained in terms of the distribution of other significant factors. Resin-retained restorations made with minimal tooth preparation are shown to be capable of extended clinical service and their failure rarely resulted in adverse consequences for the patient. Patient satisfaction with their treatment was reportedly high.
