Purpose: The study compared the effect of pre-processed surface treatment such as sand blasting and grinding of ridge lap area of the acrylic teeth on the tensile strength and bond strength of the permanent denture base fabricated with different curing techniques. Materials and methods: Ridge lap surface areas of the acrylic maxillary anterior teeth were treated with sandblasting and grinding procedure. Specimens were fabricated and processed with conventional heat cured, microwave cured and self cured techniques. Specimens were subjected to bond strength and tensile strength testing. Results: Sandblasting in all type of curing possessed higher bond and tensile strength. Grinding method yielded higher bond and tensile strength compared to control groups. Conclusion: It is recommended sandblat the ridge lap area of the acrylic denture teeth prior to denture base processing. KEYWORDS: Bond strength; conventional cure; microwave cure; sand blastin
