Conveniently-cleaned passive slip cover self-ligating bracket

Abstract

The invention discloses a conveniently-cleaned passive slip cover self-ligating bracket comprising a bracket net bottom and a bracket wing body, wherein an archwire groove is formed in the bracket wing body; a slip cover covering above the archwire groove is arranged between bracket wings; a limiting groove with two closed ends is formed in the middle of the slip cover; a locating pin sliding in the limiting groove is arranged at a step located at one side between the bracket wings; two ends of the limiting groove are respectively provided with a clamping position for opening and closing the slip cover; each clamping position is internally provided with a locking bulge matched with the locating pin in a clamping way; and a triggering hole for opening the slip cover is formed in the jaw edge of the slip cover. The bracket disclosed by the invention is convenient to clean; the slip cover is good in structural strength and not easy to drop; and the slip cover is convenient to lock and unlock without special tools.

Description

technical field [0001] The invention relates to the technical field of orthodontic equipment, in particular to a convenient and clean passive sliding cover self-locking bracket. Background technique [0002] Appliance is a device for treating malocclusion (additional occlusion), or orthodontic appliance. It can generate force, or use the appliance to change the deformed frontal bone and misplaced teeth through the periodontal support tissue through the functional force of the masticatory muscles and perioral muscles, so as to facilitate the normal growth and development of the maxillofacial teeth. [0003] The bracket is an important part of the fixed appliance. It is directly bonded to the surface of the crown with an adhesive, and the archwire exerts various types of orthodontic force on the tooth through the bracket. Brackets are made of stainless steel, bioceramic or composite resin, and their main function is to fix the arch wire, so that the arch wire can play a bette...

AI Technical Summary

Problems solved by technology

[0008] (1) The limit slot in the middle of the bracket cover is short, which makes it difficult to clean the arch wire slot;

[0009] (2) The limit groove and the buffer groove extend to the side edge of the bracket cover, destroying the overall structure of the bracket cover, resulting in reduced strength, easy deformation, and clinically there is a risk of falling off;

[0010] (3) The bracket cover must be driven by special tools, which is difficult to operate
