Self-locking bracket and orthodontic appliance

Abstract

The invention relates to the technical field of orthodontics, and discloses a self-locking bracket. The self-locking bracket comprises a bottom plate, a bracket body, a self-locking cover and a lock cylinder, wherein the bottom plate is used for being connected to the lip side face or the tongue side face of a tooth; the bracket body is connected to the side face, back to the tooth, of the bottom plate; a groove used for containing an arch wire is formed in the bracket body; the self-locking cover is arranged on the bracket body and used for covering the groove; a sliding groove is formed in the side, facing the bracket body, of the self-locking cover; the lock cylinder is made of an elastic material and comprises a fixed section fixedly connected with the bracket body and a deformation section arranged in the sliding groove; and the middle of the deformation section is hollowed out and forms a gap. The self-locking bracket provided by the invention is simple and reliable in structure, convenient to operate and easy to clean, the self-locking cover does not shake during use, and self-locking performance is stable. The invention also provides an orthodontic appliance which adopts the self-locking bracket. Thus, the orthodontic appliance also has the advantages of simple and reliable structure, convenience in operation, easiness in cleaning, stable self-locking performance and the like.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a self-locking bracket and an orthodontic device. Background technique [0002] Fixed orthodontic treatment is one of the most common methods in orthodontic treatment. It is mainly completed by bracket aligners. In actual operation, the brackets are bonded to the surface of the patient's teeth and matched with the fixed archwires set in the bracket grooves. The orthodontic force is generated by the deformation of the arch wire, and then the teeth are arranged and moved to achieve the purpose of orthodontics. In the prior art, elastic ligature rings or ligature wires are usually used to bind the archwire around the ligature wing to complete the fixation of the archwire. This method tends to increase the friction between the bracket and the archwire, and the corresponding The speed of tooth movement will be reduced, resulting in a longer treatment cycle. In addition, during ...

AI Technical Summary

Problems solved by technology

In the prior art, elastic ligature rings or ligature wires are usually used to bind the archwire around the ligature wing to complete the fixation of the archwire. This method tends to increase the friction between the bracket and the archwire, and the corresponding The speed of tooth movement will become smaller, resulting in a longer treatment cycle

In addition, during the treatment process, the arch wire needs to be replaced regularly according to the progress of the treatment. Every time the arch wire is replaced, the ligature ring or ligature wire needs to be removed, which increases the operation of medical staff and virtually increases the treatment time, which is not conducive to improving the treatment efficiency.

[0003] Of course, in order to improve the efficiency of correction, there are some self-locking brackets that do not require ligature rings or ligature wires in the prior art, but the structure of these self-locking brackets has unreasonable switch lock structure, complex structure, difficult operation, and difficult cleaning. , high manufacturing difficulty, low manufacturing precision and other issues, need to be further optimized
