Problems solved by technology

However, since the process of positioning the brackets on the orthodontic model will depend on the doctors involved in the treatment, different doctors may have different bracket positioning results for the same patient, and different positioning results will produce different shifts. Trays, so the accuracy of positioning the brackets on the existing transfer trays is low, and then positioning and bonding the brackets through inaccurate transfer trays will lead to inaccurate orthodontic results

Abstract

The invention discloses a generation method and a generation device of a transfer tray, relating to the medical field of orthodontics, and solving the problem that in the prior art, the indirect adhering manner is adopted, so that the bracket positioning accuracy rate is low by adopting the transfer tray. The main technical scheme is as follows: the generation method comprises the following steps: acquiring a target tooth arrangement three-dimensional model corresponding to dentition needing orthodontics; arranging a bracket on the target tooth arrangement three-dimensional model according to tooth positions and based on the target tooth arrangement three-dimensional model and correcting arch wires; restoring the tooth positions in the target tooth arrangement three-dimensional model provided with the bracket to the positions in the untreated state; generating a transfer tray model according to the restored target tooth arrangement three-dimensional model; and generating a transfer tray according to the transfer tray model, wherein the transfer tray comprises an inner tray body and an outer tray body. The method and the device are mainly used for generating the transfer tray.

Description

technical field [0001] The invention relates to the medical field of orthodontics, in particular to a method and device for generating a transfer tray. 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. The transfer tray is used in orthodontics. The bracket (orthodontic d...
