Tensile bond strength of heat and self-cured acrylic denture base resins to the inner and outer layers of two-layered acrylic resin denture teeth.

The tensile bond strength of the inner and outer layers of two-layered acrylic resin denture teeth to heat cured and self-curing acrylic resin denture base material was tested. The bond between the heat-cured resin and the inner layer of the denture teeth was significantly stronger than the bond between the heat-cured resin and the outer layer of the denture teeth. The bond between both layers of the denture teeth and the self-curing acrylic resin was significantly weaker than with the heat-cured acrylic resin.
