Abstract

Background:  Poly (methymethacrylate) (PMMA) is still the most predominantly used denture base material because of its many characteristics such ease in processing, stability in oral environment, lightweight, excellent aesthetic properties, low cost, low water sorption and can easily be rechanged and repaired its shape. But, it has certain drawbacks like residual monomer allergy, low modulus of elasticity, low impact strength, low flexural strength, polymerisation shrinkage,porosity, crazing, warpage. This paper reviews reinforcement of poly(methyl methacrylate) (PMMA) acrylic denture base resin. The review is based on scientific reviews, papers, and abstracts, as well as studies concerning the effect of additives, fibers, fillers, and reinforcement materials on PMMA, published between 1974 and 2019. Many studies have reported improvement of PMMA denture base material with the addition of fillers, fibers, nanofiller, and hybrid reinforcement. However, , most of the studies, without bioactivity and clinical implications, were limited to in vitro work. There is no ideal denture base material, but with some modifications, especially with the addition of silanized nanoparticles and a hybrid reinforcement system, the properties of PMMA could be improved.
