Conventional tooth preparation of abutment teeth often involves removal of significant amount of tooth structure. When the abutment tooth is sound, conventional full coverage procedures seem to be quite radical. More conservative procedures, such as partial veneer crowns or pin-retained restorations, present limitations in esthetics and retention. Many patients object to these drawbacks. The development of acid etching of enamel to improve the retention of resin, described by Buonocore, in 1955, has proven to be effective in bonding fixed partial dentures to tooth by less destructive means. The following article presents a series of case reports of treatment of single edentulous space with resin bonded prosthesis.
