Abstract

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
