Unilateral posterior tooth reverse occlusion orthodontic apparatus

Abstract

The invention provides a unilateral posterior tooth reverse occlusion orthodontic apparatus which comprises a jaw pad, a base bracket, a spiral expander, a first anti-crack component, a second anti-crack component, adjacent hooks, an outward pushing assembly, a cheek screen and at least two jaw crossing steel wires. Two ends of the spiral expander are connected with the first anti-crack component and the second anti-crack component, the first anti-crack component is arranged in the jaw pad, the second anti-crack component is arranged in the base bracket, each jaw crossing steel wire comprises a jaw-direction portion and a cheek-direction portion, one end of each jaw-direction portion is arranged in the base bracket, the other end of the each jaw-direction portion crosses the sulcus vestibularis of a corresponding reverse occlusion tooth to be connected with the corresponding cheek-direction portion, each cheek-direction portion is arranged on a cheek side of the corresponding reverse occlusion tooth and is arranged in the cheek screen, and the outward pushing assembly comprises more than one hyperbolic tongue spring for providing outward thrust for the reverse occlusion teeth. The unilateral posterior tooth reverse occlusion orthodontic apparatus has the advantages that effective and quick orthodontic treatment can be carried out on the reverse occlusion teeth by the aid of the unilateral posterior tooth reverse occlusion orthodontic apparatus, and the orthodontic time can be shortened to a great extent, can be shortened from the existing orthodontic time of 4-6 months and is 1-2 months.

Description

technical field [0001] The invention relates to a unilateral posterior crossbite corrector. Background technique [0002] Unilateral posterior crossbite is a relatively common malocclusion in clinical practice. The vast majority of patients are accompanied by unilateral maxillary dental arch narrowing and facial asymmetry, which will seriously affect the growth and development of temporomandibular joints. Early correction of unilateral posterior crossbite is of great significance for correcting the adverse growth and development trend in the horizontal direction of the face and forming a balanced and stable occlusal relationship. [0003] The currently used orthodontic treatment is through the interactive traction of the upper and lower teeth, and the patient cooperates with the elastic band to solve the underbite through the inclined movement of the teeth. In this way, it is easy to cause the occlusal plane to deviate and the posterior teeth to elongate. [0004] In addit...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a unilateral posterior crossbite orthodontic device to solve the problems existing in the prior art that easily cause the occlusal plane to deviate, the posterior teeth are elongated, the correction time is relatively long, and the effect is relatively unsatisfactory.
