A complete denture replaces the entire dentition and associated structures of the maxilla and mandible. It consists of artificial teeth attached to a denture base, which is composed of denture base resin. There are several types of denture base resins including heat polymerizable, autopolymerizable, thermoplastic blanks, light activated materials, and microwave cured materials. Heat activated denture base resin is commonly used and involves processing the resin in a water bath at temperatures ranging from 74°C to 100°C to induce polymerization. Chemically activated resin polymerizes at room temperature and is often used for temporary or repair work. Processing errors can occur with shrinkage, porosity, crazing or creep depending on the
