title: Comparative bond strengths of light-cured, heat-cured, and autopolymerizing denture resins to denture teeth.
abstract: Standard and interpenetrating polymer network acrylic resin denture teeth were milled into cylinders 8 mm in diameter and processed against cylinders of the three different resins. The specimens were reduced by milling to a diameter of 6 mm in the region of the tooth-resin interface and thermocycled for 24 hours. Specimens were then subjected to tensile loading until fracture. Group means were compared by using the Duncan multiple range test at the 5% level of significance. The strongest bond occurred between the heat-cured resin and the standard acrylic resin teeth. Intermediate strength was achieved with the heat-cured resin to the IPN teeth and the autopolymerizing resin to both types of teeth. Lowest strength was measured with the light-cured resin to both types of teeth.
