摘要:
Provided is a molded body for dental use, said molded body being made from a polyester resin which as a material for esthetic dentures exhibits excellent fracture resistance and moderate bendability, and which ensures excellent polishability during denture fabrication, and has an alkali resistance which prevents a denture from fracturing due to denture cleaning. This molded body for dental use is made from a polyester resin which is composed of a dicarboxylic acid component containing a terephthalic acid residue, and a glycol component containing a 2,2,4,4-tetramethyl-1,3-cyclobutanediol residue and a 1,4-cyclohexanedimethanol residue, wherein the proportions of the terephthalic acid residue, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residue and 1,4-cyclohexanedimethanol residue in the polyester resin are 30 to 70 mol %, 5 to 25 mol %, and 25 to 50 mol %, respectively.
