Effect of Surface Treatments on the Bond Strength of Cross Linked Acrylic Resin Denture Teeth with Auto-Polymerized Acrylic Resin – An In Vitro Study
Journal Title: Scholars Journal of Dental Sciences - Year 2018, Vol 5, Issue 5
Abstract
Abstract: To evaluate and compare the effects of chemical and mechanical treatment of the ridge lap surface of acrylic teeth on the bond strength of acrylic resin teeth to denture base resins. A total of 40 specimens were acrylized using heat-polymerized acrylic resin with specific dimensions which has a ditch of specific dimension on the superior surface and molar tooth was arranged on the superior surface. The specimens were divided into 4 groups according to the treatment done on the ridge lap area and then subjected to hardness test using universal testing machine. Statistical analysis was done using one way ANOVA test and Tukey HSD post hoc test. Group C showed maximum bond strength and Group A showed the minimum bond strength. Group B & D showed increase in bond strength compared to control group. Sandblasting the ridge lap area and treating it with chemical agents like methyl methacrylate monomer and acetone increases the bond strength with denture base acrylic resin significantly.
