A kind of orthodontic bracket for eliminating backlash

Abstract

The invention relates to a clearance-eliminating orthodontic bracket, comprising a bracket body, the bracket body comprising a bottom plate and a base, the base is provided with an upper limit wing and a lower limit wing on the side away from the bottom plate, and the base is far from the bottom plate. One side is provided with an arch wire groove for placing the correction arch wire between the upper limit wing and the lower limit wing, the base is provided with a movable groove which is vertically communicated with the arch wire groove, and a pressing block is slidably connected in the movable groove. A through hole is formed through the base and the bottom plate. The through hole is provided with an elastic limit rod that is inserted into the abutment block. The axis of the limit rod and the sliding direction of the abutment block have an included angle. The distance between the side walls extending into the archwire slot and farther from the archwire slot is smaller than the width of the archwire slot. By adopting the above technical solution, the abutting block reduces the gap between the correction arch wire and the arch wire groove, so that the correction arch wire and the arch wire groove are tightly pressed, thereby improving the torque and correction of the correction arch wire during the correction process. The effect of force expression.

Description

technical field [0001] The invention relates to the technical field of orthodontic brackets, in particular to an orthodontic bracket for eliminating gaps. Background technique [0002] At present, when doctors use orthodontic appliances to carry out oral orthodontic treatment in clinic, the brackets are bonded to the tooth surface, the orthodontic archwires pass through the archwire grooves on the brackets, and steel wires or rubber rings are used to ligate the orthodontic archwires on the tooth surface. In the groove of the bracket, the force of the orthodontic arch wire drives the bracket to apply force to the teeth, so as to achieve the effect of oral orthodontics. [0003] Because a series of sizes of orthodontic archwires are used in the process of orthodontic treatment, usually the section size is small to large, from circular section to square section, so the bracket body will change the size of the archwire groove during the manufacturing process. The setting is lar...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned existing technical solutions have the following defects: in this solution, the elastic pin shaft is plugged and matched with the bracket body, but in daily life, actions such as eating and brushing teeth will exert external force on the bracket, so that the elastic pin shaft is easy to connect with the bracket body. The tank body is separated, causing problems such as causing users to swallow it incorrectly, affecting the torque expression of the orthodontic archwire, and reducing the correction effect, so there is still room for improvement
