A prospective study was undertaken in a dental teaching hospital to compare the clinical performance of cantilever resin-bonded bridges with a fixed-fixed design for the replacement of a maxillary permanent incisor. A total of 25 anterior resin-bonded bridges was placed in 24 patients. The prostheses were evaluated over 14 to 45 months. During the evaluation period only one fixed-fixed type debonded, which was subsequently rebonded successfully. There was no debond in the cantilever group. The short-term, initial findings showed that cantilever resin-bonded bridges performed as successfully as their fixed-fixed counterparts and were considered to be an acceptable form of restoration.
