Title
(EN) Method for generating tooth restart arrangement scheme for orthodontic treatment
(ZH) 产生牙齿正畸治疗重启排牙方案的方法
Abstract
(EN) The invention provides a method for generating a restart tooth arrangement scheme, and the method comprises the steps: obtaining a first group of M tooth three-dimensional digital models which respectively represent the last M successive tooth layouts in the previous tooth arrangement scheme of a dentition; obtaining a first tooth three-dimensional digital model which represents the tooth layout of the dentition during the re-enlightenment orthodontic treatment; and generating a restart tooth arrangement scheme based on the first tooth three-dimensional digital model and the first set of tooth three-dimensional digital models, where M is a natural number greater than 2, the tooth arrangement scheme comprises a plurality of successive tooth layouts from an initial tooth layout to a target tooth layout, and a path of tooth orthodontic treatment is represented.
(ZH) 本申请的一方面提供了一种产生重启排牙方案的方法,包括:获取第一组M个牙齿三维数字模型,分别表示一牙列前次排牙方案中最后M个逐次的牙齿布局;获取第一牙齿三维数字模型,其表示重启正畸治疗时所述牙列的牙齿布局;以及基于所述第一牙齿三维数字模型和所述第一组牙齿三维数字模型,产生重启排牙方案,其中,M为大于2的自然数,排牙方案包括从初始牙齿布局到目标牙齿布局的多个逐次的牙齿布局,表示牙齿正畸治疗的路径。
