Material for denture base, denture base, method of manufacturing the denture base, plate denture, and method of manufacturing the plate denture

A material for a denture base containing a polymer component containing an acrylic resin,

• 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, and
• wherein, when the material for a denture base is formed into a notched test piece having a length of 39 mm, a height of 8 mm, and a width of 4 mm, the test piece exhibits 1.9 MPa·m1/2 or more of maximum stress intensity factor measured by a fracture toughness test in accordance with a flexural test in accordance with JIS T6501 (2012) under a condition of a testing speed of 1 mm/min, and exhibits 900 J/m2 or more of total work of fracture.
