Claims27
A material for a denture base containing a polymer component, the polymer component having a weight average molecular weight of 1,200,000 or more and containing an acrylic resin,
- wherein the acrylic resin is a polymer obtained by polymerizing a monomer component comprising 95% by mass or more of at least one selected from the group consisting of methacrylic acid and methacrylic acid alkyl ester, and
- wherein a content of the acrylic resin is 95% by mass or more based on a total amount of the material for a denture base.
A material for a denture base, wherein:
- when the material for a denture base is formed into a test piece having a length of 80 mm, a width of 10 mm, and a thickness of 4 mm, the test piece exhibits 110 MPa or more of flexural strength measured by a three-point flexural test in accordance with JIS K7171 (2008) under conditions of a testing speed of 2 mm/min and a length of a support span of 64 mm,
- the material for a denture base contains a polymer component that is at least one selected from the group consisting of a sulfone-based resin and an ether ketone resin;
- and
- a content of the polymer component is 90% by mass or more based on a total amount of the material for a denture base.
