title: The bonding of cold-cured acrylic resin to acrylic denture teeth.
abstract: The necessary improvement of the bonding of denture teeth to the base resin has been hampered by inconsistent results and the consequent lack of clear guidance as to the best procedure to use. This state of affairs is in part due to poor experimental design. The tensile strength of notched planar interfaces between acrylic denture tooth material and cold-cured acrylic resin was determined for various treatments under a protocol designed to minimize spurious failures. The tooth material treatment consisting of grinding and exposure to a methyl methacrylate-trichloromethane mixture was, of those treatments, the most reliable in that no interfacial failures were observed. Strength was indistinguishable from that of both tooth and base acrylic under the same conditions.
