Orthodontic appliance and orthodontic method

Abstract

The invention relates to an orthodontic appliance. The orthodontic appliance includes orthodontic appliance bodies, a main orthodontic wire and an auxiliary orthodontic wire, and at least two orthodontic appliance bodies are arranged; each orthodontic appliance body includes a bottom plate, a bracket body and an installation member, the bottom plate is used for being fixedly connected to the tongue side surface of a tooth, the bracket body is arranged on the side surface, opposite to the teeth, of the bottom plate, the bracket body is provided with a main groove, the installation member is fixedly connected to one end, far away from gums, of the bracket body, and the installation member, the bracket body and the bottom plate form an auxiliary groove; the main orthodontic wire is stuck in the main groove of each orthodontic appliance body; and the auxiliary orthodontic wire is stuck in the auxiliary groove of each orthodontic body. The orthodontic appliance corrects the teeth through the double orthodontic wires, can effectively control three-dimensional movement of the teeth, and has a rapid correction speed and a good correction effect. The invention also relates to an orthodonticmethod. The method uses the orthodontic appliance and a bracketless invisible correction device to correct the oral problems of a patient, and combines the bracket correction technology with the bracketless correction technology to realize complementary advantages, thereby greatly improving the correction efficiency.

Description

Technical field [0001] The invention relates to the technical field of orthodontics, in particular to an oral appliance. Background technique [0002] With the development of society and the continuous improvement of people's quality of life, people pay more and more attention to the beauty of teeth, and orthodontic treatment technology is rising rapidly. Common orthodontic techniques are divided into bracket-free invisible orthodontics and bracket-type orthodontics. Bracket-free invisible orthodontics is mainly achieved by wearing and regularly replacing transparent aligners to achieve the correction of teeth. It performs well in pushing molars and other aspects; the bracket orthodontic technology uses the interaction force between the orthodontic wire and the bracket with grooves on the patient's tooth surface to move the teeth, which can close the gap and realize the control of the teeth Fine movement. [0003] However, the existing bracket-type braces only have one groove, an...

AI Technical Summary

Problems solved by technology

[0003] However, the existing bracket-type aligners only have one groove, and only one aligning wire can be used. It is difficult to control the three-dimensional movement of the teeth, and it is also difficult to accurately control the movement of the teeth, resulting in the incomplete realization of the expected correction effect. Without brackets Invisible aligners also cannot effectively control the fine movement of teeth
