Title:
ORTHODONTIC AUTOMATIC TOOTH ARRANGEMENT METHOD AND SYSTEM BASED ON MESH FEATURE DEEP LEARNING
Document Type and Number:
WIPO Patent Application WO/2024/082284
Kind Code:
A1
Abstract:
An orthodontic automatic tooth arrangement method and system based on mesh feature deep learning. The method comprises: acquiring a tooth triangular mesh three-dimensional model for tooth arrangement; and inputting the tooth triangular mesh model into a pre-trained deep learning model, so as to obtain a predicted tooth position of a tooth arrangement result. The deep learning model comprises a first feature encoder, a second feature encoder, and a feature decoding and mapper, wherein the first feature encoder takes a tooth triangular mesh three-dimensional model as an input, so as to obtain a tooth shape feature, the second feature encoder takes a dentition point cloud as an input, so as to obtain a global dentition feature, and the feature decoding and mapper obtains a predicted tooth arrangement result on the basis of the tooth shape feature and the global dentition feature.
