Functional modifications of denture base resin - A review

In the year 1930s, acrylic resins were established. The materials used for denture base are vulcanite, celluloid & phenol-formaldehyde. The limitations were founded those were high coefficient of thermal expansion, thermal shrinkage, poor colour stability of self-cured resins, porosity, crazing, warpage, poor adhesion to metal and porcelain retention. Denture base resins are widely used till date as it has its own significance. But recently there has been much advancement in the denture base resin field to control and to invent a new denture base resin. Methyl methacrylate chemical compound of denture base resins was changed with many monomers to attain higher physicomechanical properties while not compromising the biocompatibility. However, there is not any consensus on the most effective strategy to attain the best changed chemical compound, to identify and evaluate the variations within the properties between typical and changed monomers and to verify the effect of many variables on the properties of dental plate base acrylic. The present review shows the different advancements in the area of denture base resins.
