N2  - This study aimed to investigate the shear bond strength of PMMA teeth treated with ridge lap surfaces and high-impact injection-molded denture foundations. A black line was drawn 1 mm above the ridge lap area on 51 samples. The samples were divided into three groups: diatoric cavity ridge lap samples (group C), sandblasted ridge lap samples (group B), and the control group (group A). The samples were then placed in a 7.5 x 7.5 mm mold. The shear bond strength of the retrieved samples was evaluated using a universal testing machine, and the wax patterns were created using injection molding. Groups A, B, and C had mean shear bond strengths of 991.29, 1038.71, and 1187.41, respectively, with a P-value of 0.010. There was a statistically significant difference between groups C and A (P-value > 0.05). The results obtained were statistically analyzed using SPSS version 17, especially post hoc tests and one-way ANOVA analysis. This analysis revealed that the samples in group C had a higher shear bond strength due to the preparation of the diatoric cavity, increasing the surface area of the ridge lap section.
