Purpose: The aim of the present study was to evaluate and compare the flexural strength of self-cure and visible light cure denture base resin as repair material using different design of repair. Material and Method:Forty samples of dimensions 65 x 10 x 2.5 mm were made of heat cure acrylic resin and the prepared intact specimens were divided into two equal parts, i.e. 31mm each. Samples in pairs were placed in the mould of dimension 65 x 10 x 2.5 mm with 45° bevel and butt joint design and a gap of 3 mm was created in middle of mould for adhering with self cure and visible light cure repair material. Testing was done for flexural strength on Universal testing machine. Result: Significant differences were found among the groups in terms of repair resin type (P < 0.001). Flexural strength of samples with bevel design and repaired with self cure resin was higher than those repaired with visible light cure resin. Conclusion:The repair design and procedure with self cure acrylic resin exhibited significantly higher flexural strength than that of visible light-cure resins.
