Protocols of improvements for PMMA denture base resin: An overview

Polymethyl methacrylate (PMMA) is a polymer that expansively employed in denture base construction due to its low cost, aesthetics, lightweight, reparability, and processability. Nevertheless, this material not ideal fulfill the mechanical physical characteristics of dental restorations. Despite popularity thermal polymerization method, main shortcoming prolonged curing period. Thus, correctly selecting cycle post-polymerization treatment needed achieve promising outcomes. In autoclave polymerization, pressure plays crucial function accelerating initial as well decreasing pores remaining monomer level, thereby improving flexural strength. Besides, ultrasound can speed up conventional chemical reactions by generating intensive local heating, higher pressures, very short periods. This article reviews currently protocols for enhancing PMMA polymers discusses properties modified acrylic materials. Moreover, work explores effects treatment, process, ultrasonic gamma irradiation on performance, positive influence these treatments functional clinical longevity.
