To provide a method for automatically generating a prosthesis from a three-dimensional scan data by generating an intermediate surface of the prosthesis, generating an inner surface of the prosthesis, generating an outer surface of the prosthesis, and connecting the intermediate surface of the prosthesis and the outer surface of the prosthesis.SOLUTION: A method for automatically generating a prosthesis from a three-dimensional scan data includes: generating an intermediate surface of the prosthesis extending from a margin line of a prepared tooth in the three-dimensional scan data toward an outside of the tooth; generating an inner surface of the prosthesis by setting a gap from a surface of the prepared tooth; generating an outer surface of the prosthesis; and connecting the outer surface of the prosthesis and the intermediate surface of the prosthesis.SELECTED DRAWING: Figure 1 【課題】補綴物の中間面生成、補綴物の内面生成、補綴物の外面生成、及び補綴物の中間面と補綴物の外面を連結するステップにより、３次元スキャンデータから補綴物を自動で生成する方法を提供する。【解決手段】３次元スキャンデータから補綴物を自動で生成する方法は、３次元スキャンデータ内の調製済み歯のマージンラインから歯牙の外部に向かって延在する補綴物の中間面を生成するステップと、前記調製済み歯の表面から間隔を設定して、前記補綴物の内面を生成するステップと、前記補綴物の外面を生成するステップと、前記補綴物の外面及び前記補綴物の中間面を連結するステップとを含む。【選択図】図１
