ABSTRACT:
A thermally deformable denture base adapted to be fitted to an edentulous ridge and the surrounding tissue surfaces and a method of producing and fitting complete dentures incorporating the thermally deformable denture base. The denture base has an inner surface and an outer surface and is formed by a molding process from a doughy mixture of a plasticized liquid monomer and a methyl methacrylate polymer powder in a 1:3-3.5 ratio. When heated to a temperature above about 135.degree. F., the denture base is malleable and may be molded in the mouth of a patient to attain an approximation of the tissue surfaces. The denture base may be incorporated into a complete denture by curing an unpolymerized resin material denture liner to the inner surface of the denture base and affixing teeth to the outer surface of the denture base.
