Summary: | To provide a method of automatically generating a prosthesis from three-dimensional scan data and a computer-readable recording medium recording a program for causing a computer to perform the same.SOLUTION: A method of automatically generating a prosthesis from three-dimensional scan data includes the following steps of: automatically extracting from the three-dimensional scan data teeth information on each tooth included in the three-dimensional scan data; automatically extracting a margin line with respect to a prepared tooth; generating a plurality of two-dimensional images having the prepared tooth and an adjacent tooth adjacent to the prepared tooth; automatically generating three-dimensional temporary prosthesis data on the basis of the plurality of two-dimensional images; and deforming a single tooth model corresponding to the prepared tooth by using the margin line and the three-dimensional temporary prosthesis data, and generating three-dimensional prosthesis data.SELECTED DRAWING: Figure 1
【課題】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、及びこれをコンピュータで実行させるためのプログラムが記録されたコンピュータ読取り可能な記録媒体を提供する。【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から、前記3次元スキャンデータ内に含まれる各歯牙の歯牙情報を自動で抽出するステップと、調製済み歯に対して、マージンラインを自動で抽出するステップと、前記調製済み歯と、前記調製済み歯に隣接した隣接歯とを有する複数の2次元画像を生成するステップと、前記複数の2次元画像を基に、3次元臨時補綴物データを自動で生成するステップと、前記マージンライン及び前記3次元臨時補綴物データを用いて、前記調製済み歯に対応する単一歯牙モデルを変形して、3次元補綴物データを生成するステップと、を含む。【選択図】図1 |
