Abstract: A computer-implemented geometric processing method generates the design for a model of a dental prosthesis beginning with obtaining a blended prosthesis dataset for dental prostheses including natural tooth data and prosthesis tooth data designed by a technician. This dataset is preprocessed by generating a depth map with preprocessing so that the data is more suitable for deep learning (DL) so as to ensure generation of a smooth surface. An artificial intelligence neural network generation model with tooth feature loss is trained on the preprocessed dataset and is used to form a model of the prosthesis. Then the dental information associated with the dental model of dentition is used to generate a 3D dental prosthesis surface with a post-processing method to meet the requirement of the dental prosthesis. Finally, the rest of the dental prosthesis is completed to meet full function.
