Peel bond strength between a silicone-based soft liner and a heat-cured acrylic resin denture base reinforced with three concentrations of metal oxide nanoparticles

Purpose: To evaluate the effect of incorporation 0.1%, 0.3%, and 0.5% concentrations titanium oxide, aluminum silica nanoparticles in heat-cured acrylic resin denture base on peel bond strength to a silicone liner. Methods: A total number 100 samples were prepared classified into control group three groups according type nanoparticle. Each was subgroups concentration nanoparticle (n=10). Silicone based-soft liner added over specimens, measured using peeling test at an angle 90°. Statistical analysis done Two-way ANOVA for interactions between different materials their concentrations. Results: showed that did not affect strength. Conclusion: The this study effective increasing studied
