Abstract
An automated method for generating a prosthesis from a 3D scan data, the method includes extracting prep information of a prepared tooth from the 3D scan data, generating a two dimensional (“2D”) projection images by projecting the 3D scan data based on the prep information and generating a 3D prosthesis based on the 2D projection images using a generative adversarial network including a 2D encoder and a 3D decoder.

An automated method for generating a prosthesis from a three dimensional (“3D”) scan data, the method comprising:
- generating a two dimensional (“2D”) projection images by projecting the 3D scan data based on prep information of a prepared tooth from the 3D scan data;
- generating a 3D prosthesis based on the 2D projection images using a network including a 2D encoder and a 3D decoder;
- and
- generating a prosthesis answer data used for training the network,
- wherein generating the prosthesis answer data comprises:
- converting a first answer data corresponding to the prepared tooth into a second answer data having fixed connections using a deformable registration.
A generator for generating a prosthesis from a three dimensional (“3D”) scan data, the generator comprising:
- a two dimensional (“2D”) encoder which receives 2D projection images of a prepared tooth of the 3D scan data;
- and
- a 3D decoder which receives an output of the 2D encoder, and generates coordinates of points forming a 3D prosthesis for the prepared tooth,
- wherein a prosthesis answer data used for training a network including the 2D encoder and the 3D decoder is generated by converting a first answer data corresponding to the prepared tooth into a second answer data having fixed connections using a deformable registration.
