Method and system for automatically generating orthodontic brace model

The embodiment of the invention discloses a method and system for automatically generating an orthodontic brace model. The method comprises the following steps: acquiring a digital initial tooth arrangement model; removing an undercut area included in the initial tooth arrangement model, and determining a middle tooth arrangement model; carrying out nearest point projection on the initial tooth arrangement model based on the middle tooth arrangement model, and determining a target tooth arrangement model; and generating an orthodontic brace model based on the target tooth arrangement model. 本申请实施例公开了一种自动生成矫正牙套模型的方法和系统。所述方法包括：获取数字化的初始排牙模型；对所述初始排牙模型包括的倒凹区域进行移除，确定中间排牙模型；基于所述中间排牙模型在所述初始排牙模型上进行最近点投影，确定目标排牙模型；基于所述目标排牙模型，生成矫正牙套模型。
