A resin-bonded silver-palladium-copper-gold alloy overcasting restoration was incorporated with an existing maxillary anterior adjacent metal ceramic gold alloy fixed partial denture using a metal conditioner (Alloy Primer) and an adhesive resin (Super-Bond C&B Ivory). The resin-bonded overcasting restoration had been functioning satisfactorily for more than 5.5 years for the 49-year-old female patient. However, one of the retainers, which was bonded to the palatal surface of the metal ceramic restoration of the adjacent fixed partial denture, lost retention after six years. The resin-bonded overcasting restoration and the adjacent denture were completely removed and then replaced by a new large fixed partial denture with conventional metal ceramic restorations. This case report including a six-year clinical follow-up indicated that mobile abutments and a maxillary anterior location may be negative factors for resin-bonded prostheses.
