Reinforced Filler in Denture Base Materials

Abstract

Dental prosthesis nowadays fabricated from Poly (methyl methacrylate) (PMMA) due to its easy handling, exceptional appearance. However, this material as an ideal denture base is still restricted by a few limitations such as poor strength and radiopacity. Attempts to improve the mechanical and radiopacity properties of denture base materials through the inclusion of verity of fiber and fillers. A nano-filler modified with the silane coupling agent could improve the dispersiblity of the fillers in polymer matrix. The clinical problem of using silanes in adhesion promotion is bond degradation over time in the oral environment. This chapter presents the fillers as reinforcement agent for improving denture base properties. It reviews different types of fibers and fillers added to PMMA denture base resin and evaluates their effect on the physical and mechanical properties. Comprehensive research in review of literature were carried out included longstanding and update studies in electronic data base including PubMed, Google search, Science Direct and Research Gate. All studies were presented and their finding were discussed. The future of manufacturing applications in 3D printing and CAD/CAM technology of denture base resins with improvement in their properties for 3D printing technology and digital denture base fabrications was also presented.
