Method for generating tooth arrangement deep network, tooth arrangement method and device

Abstract

The invention provides a method for generating a tooth arrangement depth network and a tooth arrangement method and device.Firstly, a tooth sample corresponding to each initial dentition is obtained, and the tooth sample comprises point cloud data of each tooth in the initial dentition and standard orthodontic parameter data corresponding to a target dentition; according to the point cloud data of each tooth in the initial dentition, predicting to obtain predicted tooth arrangement result data; according to a collision loss function, a tooth arrangement loss function and an orthodontic parameter loss function, a tooth arrangement depth network is obtained through training, and the collision loss function is determined based on the collision detection distance between adjacent teeth in the predicted tooth arrangement result data. Compared with the prior art, supervised training is carried out according to the orthodontic parameter loss function, the tooth arrangement loss function and the collision loss function, and the relationship between occlusion and adjacency of adjacent teeth is considered in the process, so that gaps or collision between the adjacent teeth can be reduced, and the precision and accuracy of the tooth arrangement deep network are improved; therefore, automatic tooth arrangement is realized.
