The purpose of the current study was to evaluate clinical performance of resin-bonded fixed partial dentures (FPDs) seated with specific materials and technique. The FPDs were made from a cobalt-chromium alloy (Biocast), air-abraded with alumina, and seated with a tri-n-butylborane initiated adhesive resin (Super-Bond). Abutment enamel was etched with phosphoric acid prior to bonding procedure. A total of 10 FPDs and 20 abutments were clinically evaluated. During an average observation period of 15 years and 3 months, detachment occurred in the two abutments of different cases. An interface failure between the tooth and the luting agent was detected in one abutment, whereas recurrent dental caries was observed in the abutment of the other case. It was suggested that the materials and technique employed were clinically reliable as long as enamel surfaces had been properly etched with phosphoric acid.
