PROBLEM TO BE SOLVED: To simply provide a sophisticated artificial tooth without sacrificing any molding precision. SOLUTION: This method uses a means which injects or pours resin showing flexible viscosity at a temperature average or higher than this into an elastic impression mold which never loose flexibility at its cooling curing temperature without changing its normal state, cools the resin, releases the cooled and cured resin from the elastic impression mold, and thereafter polymerizes and cures the resin. As the resin, photopolymerization type resin is used. After pouring etc. the photopolymerization type resin to the side of a releasing surface of the elastic impression mold with a desired thickness, core material consisting of another material is supplied to its residual part. In addition, when force-fitting the core material, the elastic impression mold is heated from outside to soften the photopolymerization type resin. Consequently, sophisticated artificial tooth can be produced with techniques of a comparatively small-scale. COPYRIGHT: (C)2004,JPO&NCIPI
