Dental materials whose main component is an acrylic resin designed for use in manufacturing and/or repair of denture bases (i.e., denture rebase). These dental materials usually consist of polymethyl methacrylate or dimethacrylate (e.g., urethane dimethacrylate) composite resins, usually obtained by mixing an acrylic monomer liquid with acrylic polymers and mineral fillers. Denture base resins usually resemble natural tissue coloration and have resistance to flexure fatigue and fluids present in the oral environment; they are available in different esthetic shades. Denture-base resins are supplied in bulk packages or single-unit packets. They are used in dental laboratories usually to perform a major repair of a denture base (i.e., replace all the denture plastic material but the teeth).
