In the past, the ingredients used for the denture bases were formaldehyde of vulcanite, celluloid & phenol. Around 1930's, acrylic resins were brought into dental work. There are other disadvantages of acrylics, such as residual monomer sensitivity, weak mechanical resistance, low fatigue power, fragile on contact, weak heat conductors, low stiffness, strong thermal expansion coefficient, thermal shrinkage, bad color consistency of self-curing resins, porosity, craziness, warpage, poor metal and porcelain adhesion and mechanical retaining criteria. But they are also the most commonly used products of the denture foundation to date. The aim of this literature review was to examine the established works on denture-based resources for the manufacture of full dentures and provide historical context, current status, and potential perspectives on evolving technologies to the reader. The analysis of many dentures provides an overview of the various developments in this field. The polymers, particularly the acrylic resins, are constantly changing and the materials of choice after being in this field more than 65 year.
