Correcting bracket

Abstract

The invention discloses a correcting bracket which comprises a bracket body and a bracket cover, wherein a kidney hole is formed in a working wing of the bracket body, and a convex platform is horizontally extended on a bracket body on the left side of an arch wire trough to a direction deviating from the arch wire trough; the bracket cover is composed of a cross edge and vertical edges extending from two ends of the cross edge to the side direction of the cross edge, and shaft holes are formed in the bottom surfaces of the vertical edges of the bracket cover; the width of the bracket body is smaller than that of the bracket cover, and the bracket body is arranged between the two vertical edges of the bracket cover; pin shafts penetrate the kidney holes and the shaft holes; a bent hook is arranged on the bottom surface of the cross edge of the bracket cover and is formed in the way that the margin of the cross edge of the bracket cover is bent down and then is bent in the direction of the shaft holes, and a hook groove is formed in the bent hook; the cross edge of the bracket cover is covered on the convex platform of the left side of the arch wire trough, and the bent hook is matched with the convex platform. The bracket body and the bracket cover are simply manufactured, can adopt wire cutting for one-step forming, and are conveniently operated. Meanwhile, the width of the bracket body is smaller than that of the bracket cover, so that the size of the bracket body is smaller.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an 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 teeth. ortho...
