    Background: Wear and fracture are a frequent phenomenon observed in complete dentures. With the improper arrangement of teeth, asymmetrical arch form and in single complete denture cases where the force exerted by the natural teeth on the opposing complete denture is of centrifugal pattern, fracture along the midline is a frequently encountered mishap. Repair of the fractured denture base is a frequently performed clinical procedure. Aim: The aim of the study was to evaluate the fracture resistance of the denture base repaired with three variants in fracture site preparation. Methodology: A total of 30 rectangular specimens (50 mm × 10 mm × 1 mm) were fabricated with DPI heat cure acrylic resin, cut into two equal halves using a carborundum disc and the site of fracture was prepared with three designs: Slots placed at same level - S (Group A), slots placed at alternate level - A (Group B), and slots placed at alternate level along with surface preparation - AL (Group C). The samples were then repaired with self-cure resin, subject to three-point bending test and the fracture resistance was evaluated. Statistical Analysis: A one-way ANOVA to compare mean compressive strength values between the interventions and a Tukey HSD post hoc test for multiple comparison was performed. Results: From the statistical analysis, it is evident that preparation of fractured site with slots at alternating levels, accompanied by cameo surface preparation had greater fracture resistance than the other two groups and it was statistically significant. The Group C had the highest fracture resistance value of 13.06 ± 0.24 MPa as compared to Group B (12.49 ± 0.11 MPa) and Group A (12.37 ± 0.15 MPa). A statistically significant mean difference between slots placed at an alternate level along with surface preparation and the other two groups were observed (F = 42.176, P < 0.001). Conclusion: Denture base whose fracture site is prepared with slots placed at alternate level accompanied by surface preparation showed better fracture resistance than the other groups
