Purpose: This study evaluated the bond strength of acrylic resin denture teeth to heat cure denture base resin processed under different curing cycles and after various surface treatments on the bonding surface area of acrylic denture teeth. Materials and Methods: A two-piece metal mold of 35 mm length and 12 mm diameter was fabricated to standardize the attachment of teeth at 45°. Ninety such wax cylinders were obtained and were randomly divided and coded into three groups of 30 samples each: Group “A” – the “Control” group, Group “B” – the “MMM” group, and Group “C” – the “Acetone” group with Subgroup 1 – processing with short curing cycle and Subgroup 2 – processing with long curing cycle in each group. These 90 wax cylinder specimens were then flasked, dewaxed as per the standard protocol and surface treatment of teeth, and curing was done. The samples were tested in a universal testing machine. Results: ANOVA analysis inferred that there was a statistically significant difference between the mean bond strength values among the groups. Conclusion: Analysis of mean bond strength values reveals that the mean bond strength values of acetone were significantly higher (P < 0.05) when compared to the other groups.
