Abstract
Background: Since the 1930s, a variety of polymers have been utilized in dental operations to provide restorative dentistry, and their efficacy has been established by their morphological, biochemical, and biological properties. Inadequate design, fabrication, and/or material selection are all common causes of denture breakage. Objective: The study's goal is to test the fatigue and impact bond strength of dentures repaired using light-cured acrylic resins using various chemical solvents such as acetone, monomer, and thinner (in vitro). Materials and procedures: Heat-cure acrylic resin is used, and six sets of specimens are made using specially constructed molds, as directed on the box (5 specimens for each cured polymerization). Specimens were cut in guiding mode with a conventional positioning clamp. The samples' terminals were soaked in several solvents before repairing, including acetone, thinner, and monomer. To evaluate impact strength, silicon sheets with diameters of (50×5×4) mm were created. On an alternative bending fatigue machine, specimens with a diameter of (70× 10 X 2.5) mm were evaluated. Results: The monomer solvent's impact bond strength was found to be higher than that of the thinner solvent and the acetone solvent. Thinner solvents and monomer solvents have a lower fatigue bond strength than acetone. Acetone, thinner, and monomer were utilized as solvents, and the results of all surface treatments revealed substantial changes in mean value. Conclusions: The monomer solvent's impact bond strength was found to be higher than that of the thinner solvent and the acetone solvent. Thinner solvents and monomer solvents have lower fatigue bond strength than acetone. Acetone, thinner, and monomer were utilized as solvents, and the results of all surface treatments revealed substantial changes in mean value.
