This denture was seated on the maxillary anterior teeth with minimal tooth preparation. The RBFPD was cast from a silver-palladium alloy (Castwell M.C. 12), and the pontic was veneered with an indirect composite material (Estenia). The retainers were primed with a metal conditioner (V-Primer) and seated with a tri-n-butylborane initiated adhesive resin (Super-Bond C&B). After an observation period of eight years, a fracture occurred in the incisal edge of the central incisor abutment. The fractured area was restored with light-polymerizing composite resin and the anterior guidance was re-adjusted. DISCUSSION: RBFPD abutment teeth with deep vertical overlap should be carefully prepared to avoid abutment tooth fracture. CONCLUSION: The clinical performance of the RBFPD made from a silver-palladium-copper-gold alloy was sufficient when seated with tri-n-butylborane initiated adhesive resin after surface modification using vinyl-thiol primer. CLINICAL SIGNIFICANCE: The use of vinyl-thiol primer and tri-n-butylborane initiated adhesive resin is a clinically reliable bonding system for seating resin-bonded fixed partial denture (RBFPD) made from a silver-palladium-copper-gold alloy. The RBFPD, based on a reliable bonding system, can clinically function for a long time, even if the vertical overlap of the abutment teeth is excessive., Journal of prosthodontic research, 54(3), pp.143-146; 2010}, pages = {143--146}, title = {A nine-year clinical case study of a resin-bonded fixed partial denture seated on the maxillary anterior teeth.}, volume = {54}, year = {2010} }
