Method and device for manufacturing orthodontic bracket

Abstract

The invention discloses a method and device for manufacturing an orthodontic bracket and relates to the technical field of orthodontic bracket manufacturing, by means of the method and device for manufacturing the orthodontic bracket, the personalized orthodontic bracket can be manufactured according to the unique tooth three-dimensional anatomical structure of each patient, and the effect and efficiency of orthodontic treatment can be improved.The method includes the steps that firstly, an original three-dimensional tooth column model before orthodontic treatment is obtained; then, digital virtual orthodontic tooth arrangement is conducted on the original three-dimensional tooth column model according to the preset head shadow measurement value range of normal people and preset mark points, and a three-dimensional model of a normal tooth column state is constructed; smooth maxillary arch wires and mandibular arch wires are constructed according to the lip buccal side tooth crown state in the three-dimensional model; finally, a bracket gutter corresponding to the orthodontic bracket is constructed according to the tooth position information in the three-dimensional model and the states of the maxillary arch wires and mandibular arch wires, and a bracket bottom plate corresponding to the orthodontic bracket is constructed according to the dental crown surface form in the three-dimensional model.The method and device are suitable for processing the orthodontic bracket.

Description

technical field [0001] The invention relates to the technical field of orthodontic bracket manufacturing, in particular to a method and device for manufacturing an orthodontic bracket. Background technique [0002] With the continuous development of stomatology, orthodontic technology has been widely used. Orthodontics is mainly to adjust the coordination between facial bones, teeth and maxillofacial muscles through various orthodontic devices, and finally achieve the balance, stability and beauty of the oral and jaw system. According to statistics, more than 80% of orthodontic patients currently use traditional fixed orthodontic technology to achieve therapeutic effects, that is, orthodontic brackets are fixed on the tooth surface, and the elastic arch wire passing through the bracket groove is used to transmit the orthodontic force, so that Teeth move as expected. [0003] However, all straight wire arch brackets are pre-set with uniform parameters such as axial inclinat...

AI Technical Summary

Problems solved by technology

[0003] However, all straight wire arch brackets are pre-set with uniform parameters such as axial inclination, torque, and floor thickness during design and manufacture, and the design of these parameters comes from the average oral anatomy data of the local population. After the arch wire completes the tooth alignment and leveling stage, there is still a large gap between each tooth and the target position, which makes the final fine adjustment stage take too long
