PROBLEM TO BE SOLVED: To provide a dental prosthesis preparation device which does not require fixing of a dowel pin to a fitting plate by using gypsum.SOLUTION: A fitting plate 11 for fitting a tooth-shaped block 40 to a top surface thereof is molded by synthetic resin and a dowel pin 26 is integrally projected and molded in an under surface of the tooth-shaped block 40. Such fitting plate 11 is combined with a pedestal 10 opened upward and downward, gypsum is flown into an area between the fitting plate 11 and the pedestal 10, and thereby a work bench 13 made of gypsum including a dowel pin hole 35 which conforms with the dowel pin 26 is molded.COPYRIGHT: (C)2015,JPO&INPIT【課題】ダウエルピンを取付け板に対して、石膏を用いて固定する必要がないようにした歯科補綴物作成装置を提供する。【解決手段】歯型ブロック40をその上面に取付ける取付け板11を合成樹脂によって成形するとともに、その下面にダウエルピン26を一体に突設して成形しておき、このような取付け板11を上下に開放された受け台10と組合わせ、取付け板11と受け台10との間に石膏を流し込んでダウエルピン26と整合するダウエルピン穴35を備える石膏製の作業台13を成形する。【選択図】図1
