“…Low molecular weight PMMA has limited applications because of its poor heat resistance, poor wear resistance, poor organic solvent resistance, low hardness and easy combustion features. It has long been known that the mechanical properties of PMMA largely depend on its molecular weight [8][9][10][11][12]. Consequently, it is of great importance to develop feasible polymerization routes for the synthesis of high molecular weight PMMA.…”

Poly(methyl methacrylate) (PMMA) is widely used in aviation, architecture, medical treatment, optical instruments and other fields because of its good transparency, chemical stability and electrical insulation. However, the application of PMMA largely depends on its physical properties. Mechanical properties such as tensile strength, fracture surface energy, shear modulus and Young’s modulus are increased with the increase in molecular weight. Consequently, it is of great significance to synthesize high molecular weight PMMA. In this article, we review the application of conventional free radical polymerization, atom transfer radical polymerization (ATRP) and coordination polymerization for preparing high molecular weight PMMA. The mechanisms of these polymerizations are discussed. In addition, applications of PMMA are also summarized.

The most commonly used material in dentistry is Poly methyl methacrylate (PMMA) which has excellent properties like physical and mechanical properties but this material is rarely used in pure form as it has relatively poor wear resistance and heat resistance. The ideal properties of fixed partial denture (FPD) base material should have superior surface texture and mechanical properties. The wear resistance of heat cure provisional and CAD-CAM provisional vary greatly based on their properties. The aim of this study was to comparatively evaluate the wear resistance in heat cure provisional and cad-cam provisional fixed partial denture. Eight samples each of heat cure provisional and CAD-CAM milled FPD are prepared. The samples are then run for 8 hours in a brushing simulator with a toothpaste to check for its wear resistance .The pre test and post test measurement of its wear resistance is done using laser scan. The wear resistance is more for the CAD-CAM provisional FPD as compared to the heat cure provisional FPD. Pre treatment and post treatment cuspal thickness shows a vast difference in heat cure provisional. However the pre treatment and post treatment cuspal thickness reduction is minimal in CAD CAM provisional FPD. CAD CAM provisional FPD showed better wear resistance than heat cured provisional FPD. Hence CAD CAM prosthesis should be preferred over the heat cured FPD.
