PROBLEM TO BE SOLVED: To enable a highly-aesthetic dental prosthetic appliance with high strength to be produced depending on a shape of a prosthetic region within the oral cavity.SOLUTION: In a production method for a dental prosthetic appliance, secondary sintering is applied to a primary sintered material after formation of the primary sintered molded object molded by a powder lamination molding method using a laser beam for fine powder of a metal oxide on the basis of three-dimensional data on the dental prosthetic appliance, corrected by a volumetric change value in sintering.COPYRIGHT: (C)2015,JPO&INPIT【課題】審美性が高く、強度が高い歯科補綴物を、口腔内の補綴部位の形状に応じて、製造可能とする。【解決手段】焼結時の容積変化値によって補正された歯科用補綴物3次元データに基づいて金属酸化物の微細粉末に対しレーザ光による粉末積層造形手法で造形した1次焼結造形物を形成した後、当該1次焼結物に2次焼結を行う歯科補綴物の製造方法を提案する。【選択図】図1
