Bonding Auto-Polymerising Acrylic Resin to Acrylic Denture Teeth

Abstract - This study investigated the effect of surface treatments on the shear bond strength of an auto-polymerising acrylic resin cured to acrylic denture teeth. The surface treatments included a combination of grit-blasting and/or wetting the surface with monomer. Samples were prepared and then stored in water prior to shear testing. The results indicated that the application of monomer to the surface prior to bonding did not influence the bond strength. Grit blasting was found to significantly increase the bond strength.

KEY WORDS: Acrylic teeth, surface preparation, shear bond strength, grit blasting
