Abstract
Objective: This study was oriented to evaluate the effect of different laser surface treatment designs on improving the shear bond strength of the flexible resin to cobalt chromium denture base. Materials and methods: 30 specimens of flexible resin bonded into cobalt chromium denture base material were prepared for this study. They were divided according to the type of surface treatment as follow: Group I without any treatment (control group), Group II was treated with laser in line design. While Group III was treated with laser in a mesh design. The shear bond strength was measured using the Instron testing machine. Results: The results revealed that the highest mean values for the specimens treated with laser in mesh design while lowest mean values for the specimens of laser treated with line design and control group. Data analysis was done using one-way ANOVA and LSD-test at a significant level (p-value ˂0.05). Conclusion: within the limitation of this study, mesh laser surface treatment of CobaltChromium was improved the bond strength.
