Orthodontic bracket for teeth

Abstract

The invention discloses an orthodontic bracket. The orthodontic bracket is characterized in that chutes are symmetrically formed in two sides of a bracket opening; a hinge pin is arranged on a working wing at the left side of an orthodontic groove, and the hinge pin passes through a shaft hole all the times and is stationary relative to a bracket body; the upper end surface of the hinge pin is higher than the bottom surfaces of the chutes; a bracket cover sliding in the chutes are also matched with the hinge pin through a neck in the bottom part; the hinge pin can be blocked into different positions in the neck along with the front and back sliding of the bracket cover; the right end of the bracket can cover or move away from the orthodontic groove, and thus the bracket cover is driven to close or open. According to the orthodontic bracket, the bracket can be locked or unlocked by sliding the bracket cover, rather than overturning the bracket cover; the complicated operation of binding steel wires can be avoided in clinical application; the operation is easy.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a dental orthodontic bracket. Background technique [0002] At present, in the process of orthodontic treatment of oral teeth, the orthodontic bracket is fixed on the tooth surface, and the arch wire passes through the arch wire slot (also known as the square wire slot) on the bracket, and is bound by a rubber ring or a steel wire. The arch wire is directly ligated in the arch wire groove of the bracket, and the correction force of the arch wire is transmitted to the teeth through the bracket, so that the teeth will move as expected, so as to achieve the purpose of correcting the teeth. [0003] Since the currently used ligation rubber ring or ligation steel wire is ligated on the ligation wing of the bracket, it directly exerts force on the arch wire, which produces a large pressure on the arch wire, hinders the normal movement of the arch wire, and thus affects the normal ...

Problems solved by technology

[0003] Since the currently used ligation rubber ring or ligation steel wire is ligated on the ligation wing of the bracket, it directly exerts force on the arch wire, which produces a large pressure on the arch wire, hinders the normal movement of the arch wire, and thus affects the normal alignment of the teeth. distorted effect

At present, there are many kinds of self-locking brackets on the market, including two series of active type and passive type, but the structure is relatively complicated, the manufacture is difficult, the cost is high, the price is expensive, and the operation is difficult.
