Title:
ARTIFICIAL INTELLIGENCE-BASED METHOD AND APPLICATION FOR MANUFACTURING 3D PROSTHESIS FOR TOOTH RESTORATION
Document Type and Number:
WIPO Patent Application WO/2022/177095
Kind Code:
A1
Abstract:
The present invention relates to an artificial intelligence-based method for manufacturing a 3D prothesis for tooth restoration, the method comprising: step (a) of obtaining an image of arrangement of teeth including an abutment and a 3D modeling image of a crown which is a prosthesis; step (b) of preprocessing the 3D modeling image of the abutment and the 3D modeling image of the crown into a 2D image so as to establish a learning data set; step (c) of performing a first artificial intelligence learning by using an artificial intelligence image conversion algorithm on the basis of the abutment image and the crown image having been established into the learning data set, as reference data, and a crown image generated appropriately to be intubated into the abutment considering a shape and a size of a peripheral tooth of the abutment, as a correct answer data; and step (d) of performing a second artificial intelligence learning for extracting a 3D learning image of a crown in which a volume is assigned to the 2D learning image of the crown by using an artificial intelligence image conversion algorithm on the basis of shape information and depth information of the 2D learning image of the crown and the 2D learning image of the abutment extracted by the first artificial intelligence learning.
