Abstract


The main acrylic used to manufacture dentures is Polymethylmethacrylate (PMMA). Its mechanical properties have been improved through the incorporation of various particles of both micro and nano size and fibers. This article aims to review mechanical properties of PMMA-based denture materials. Particular attention is paid to the effect of adding fiber, filler, and nanofiller on the mechanical characteristics of PMMA. This review is based on scientific reviews, papers, and abstracts as well as studies published between 1980 and 2020 concerning the effects of surface modification, reinforcing agents, fillers, and fibers on mechanical properties of PMMA as a denture material. Numerous studies show that the addition of fibers and fillers and surface modification can strengthen the mechanical performance of PMMA-based denture materials. The results also show that most studies are limited to in vitro research without bioactivity and clinical consequences.
