Abstract

The invention discloses an automatic tooth arrangement method and an automatic tooth arrangement device, relating to the medical field of digital orthodontics, and solving the problem that the automatic tooth arrangement is poor in accuracy. The main technical scheme is as follows: the automatic tooth arrangement method comprises the following steps: acquiring three-dimensional data of dentition needing orthodontics and three-dimensional data of craniofacial jaw bone; selecting feature points on the three-dimensional data of the dentition and the three-dimensional data of the craniofacial jaw bone; constructing tooth arrangement planes and dental arch curves according to the selected feature points, wherein the tooth arrangement planes comprise a median sagittal plane, a horizontal plane and a tooth arrangement occlusal plane, and the dental arch curves comprise an upper jaw tooth arrangement curve and a lower jaw tooth arrangement curve; moving teeth in the three-dimensional data of the dentition according to the preset tooth positions, so that a target dentition after orthodontics is formed, and the preset tooth positions comprise the target upper and lower dentition sagittal position, the target upper and lower dentition vertical position, and the target upper jaw and lower jaw among-dentition position. The automatic tooth arrangement method and the automatic tooth arrangement device are mainly used for the tooth arrangement in the orthodontics.

Description

technical field [0001] The invention relates to the medical field of digital orthodontics, in particular to an automatic tooth arrangement method and device. Background technique [0002] Oral disease is a common multiple disease. According to the statistics of the World Health Organization, malocclusion has become one of the three major oral diseases (dental caries, periodontal disease and malocclusion). Dental deformities have a great impact on oral health, oral function, development and appearance of maxillofacial bones. Orthodontics has been recognized as an essential and important part of oral health care. Automatic teeth arrangement refers to the use of 3D digital imaging technology and three-dimensional modeling technology to obtain accurate three-dimensional dentition model images; Carry out automatic tooth arrangement, so as to provide prediction and evaluation for the actual tooth arrangement plan. [0003] At present, the existing automatic tooth arrangement d...
