    摘要: The present invention provides a lining material for a polymerized methylmethacrylate denture restoration which consists essentially of an admixture of approximately 40% of methylmethacrylate polymer, approximately 10% of methylmethacrylate monomer, and approximately 50% of butyl phthalyl butyl glycolate. The denture liner material is semi-cured for approximately 5 minutes at a temperature of about 160.degree.F. into a soft, tacky material having no inherent rigidity and which can be manually shaped to conform to an irregular object. The denture liner material can also be semi-cured for approximately 15 minutes at a temperature of 160.degree.F. into a somewhat hard material which is capable of being softened by application of heat and pressure. Both the soft semi-cured liner material and the somewhat hard semi-cured liner material are capable of being finally cured with a polymerized methylmethacrylate denture and adhered thereto to provide a soft liner therefor. The invention also provides methods for preparing the liner material and for adhering it to a polymerized methylmethacrylate denture.
