Abstract

This study aimed at comparing the shear bond strength between high-impact injection-molded denture base and ridge lap surface-treated PMMA teeth. A total of 51 samples were scribed with a black line 1mm above the ridge lap area. Samples were grouped into Group A  as the control group, Group B sandblasted ridge lap samples, and Group C  with diatoric cavity ridge lap samples. Then, the samples were placed in a mold of dimension 7.5×7.5mm. The wax patterns were processed through injection molding and the retrieved samples were subjected to shear bond strength assessment in a Universal testing machine.

The mean shear bond strength of Groups A, B, and C was 991.29, 1038.71, & 1187.41, respectively with a p-value of 0.010. A statistically significant difference was observed between Group C and Group A (P>0.05). The obtained values were analyzed statistically with post hoc and one-way ANOVA tests using SPSS statistical software 17. This study concluded that the samples of Group C exhibited higher shear bond strength because the surface area of the ridge lap portion increases with diatoric cavity preparation.
