This case report describes application of a metal bonding system in fabrication of a composite resin veneered fixed partial denture (FPD) with reduced retentive structure. A four-unit framework was fabricated with a silver- palladium-copper-gold alloy (Castwell M.C.12). The surface to be veneered was air-abraded with alumina, followed by priming with a metal adhesive agent (V-Primer). The framework was then veneered with a light-polymerized composite material (Cesead). The completed FPD was seated with a glass ionomer luting agent (HY-Bond Glass Ionomer). After an observation period of five years and two months, the FPD was functioning satisfactorily. The technique described here is applicable in fabrication of composite veneered restorations for vital abutment teeth. (Asian Pac J Dent 2012; 12: 7-10.)
