Abstract
In accordance with the present invention, there can be provided a denture base for a dental prosthesis comprising a body having an inner surface to be in contact with patient's alveolus ridge; a lining layer covering the inner surface of the body; and an adhesive agent for bonding the lining layer to the inner surface of the body; wherein the body is made of polymethyl methacrylate; the lining layer is made of a rubber-like resilient material comprising an olefin thermoplastic elastomer; and the adhesive agent contains a copolymer comprising an olefin and methyl methacrylate. The denture base has an advantage that adhesive force between the lining layer and the body is strong, and the lining layer has suitable hardness for supporting the dental prosthesis.
