Reducing the need to maintain fixed complete dentures by providing gold occlusal surfaces: A clinical report

Abstract

The excessive occlusal wear of complete-arch implant-supported prostheses made with metal and acrylic resin is a clinical complication that can require repeated maintenance in certain patients. A patient who presented with moderate occlusal wear of the prosthetic teeth and substantial fracture of the maxillary anterior acrylic resin base only 2 years after a previous replacement of the acrylic resin base and denture teeth is described. Because of the patient's history and existing wear, both the maxillary and mandibular prostheses were repaired by replacing the acrylic resin bases and resin denture teeth but with the addition of cast gold occlusal surfaces on the posterior prosthetic teeth. The provided treatment helped this patient, who was likely to need more frequent maintenance visits in the future because of his history of accelerated occlusal wear and increased occlusal force.
