A metal insert to replace a fractured segment of a mandibular complete denture

When surgical reduction is not possible for edentulous patients with little space between the retromolar pad and the maxillary tuberosity, dentures are most often made quite thin and as such are prone to fracture. When fracture of the lower denture base occurs, the denture is rebased, incorporating a cast metal insert in the region of the previous fracture. Following the impression procedure, a pattern is developed on the master cast of the area to be replaced in metal. A casting is made in silver-palladium alloy and incorporated in the final wax-up. The denture is then processed by joining the metal insert into the denture.
