Abstract

The purpose of this investigation was to study the Knoop hardness test, absorption and solubilityin MMA, and filler contents of the commercially available several cross-linked plastic denture teeth.<BR>In addition, tensile bonding strength of three denture base resins, heat-cured resin, heat-shock resin, andauto-cured resin, bonded to the artificial teeth was measured. Four cross-linked plastic denture teeth and oneconventional acrylic denture tooth were studied.<BR>Knoop hardness in the enamel of the specimens was as hard as the commercially available compositeresins for crown and bridge.<BR>The enamel contained 25-45% filler. The enamel had high cross-linked polymer, so the rates of swellingand solubility in MMA of the enamel were lower than the body of the specimens and the enamel and body ofplastic denture teeth.<BR>The body and dentin of the specimens showed better tensile bond strength than the enamel. Tensile bondstrength of the heat-cured resin and the heat-shock resin bonded to the body was better than the auto-curedresin bonded to the body.<BR>There was no difference in results between the body and the conventional acrylic tooth in all examinations.
