Method and device for manufacturing orthodontic bracket

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.
