Orthodontic self-ligating bracket

Abstract

The invention relates to a dental orthopaedics self-ligating bracket, and aims to provide a dental orthopaedics self-ligating bracket which is easy to use and can improve the oral health. The bracket comprises a base plate. A bracket body is arranged on the base plate. The bracket is characterized in that an arch wire groove is arranged in the bracket body. A working wing I and a working wing II are arranged at two sides of the arch wire groove. A sliding groove and a stopping groove are arranged on the working wing I. A Locking groove is arranged on the working wing II. A sliding locking plate is arranged at the top of the arch wire groove. A pair of locking hooks and a pair of stopping projections are arranged on the sliding locking plate.

Description

technical field [0001] The invention relates to a tooth appliance, in particular to a tooth orthodontic self-locking bracket. Background technique [0002] At present, the orthodontic treatment mainly uses steel wire ligation or rubber ring ligation. Both of these two ligation methods directly apply force to the orthodontic archwire, which will generate greater pressure on the orthodontic archwire. The reason is that the gap between the archwire and the archwire slot The increased friction hinders the normal movement of the arch wire, which is not conducive to the early alignment of the teeth during the orthodontic process, prolongs the treatment time, and affects the effect of orthodontic treatment. To solve this problem, there is a bracket structure on the market , the length of the ligature wing is shorter than the length of the working groove, so the ligature steel wire or rubber ring no longer directly exerts force on the arch wire, and the arch wire can move normally. ...

Problems solved by technology

[0002] At present, the orthodontic treatment mainly uses steel wire ligation or rubber ring ligation. These two ligation methods directly apply force to the orthodontic archwire, which will generate greater pressure on the orthodontic archwire. The reason is that the gap between the archwire and the archwire slot The increased friction hinders the normal movement of the arch wire, which is not conducive to the early alignment of the teeth during the orthodontic process, prolongs the treatment time, and affects the effect of orthodontic treatment. To solve this problem, there is a bracket structure on the market , the length of the ligature wing is shorter than the length of the working groove, so the ligature steel wire or rubber ring no longer directly exerts force on the arch wire, and the arch wire can move normally

However, the orthodontic brackets with this structure cannot avoid the tedious ligation process of steel wire or rubber ring, and the operation is inconvenient. The lock piece of the self-ligating bracket is turned up due to the correction force of the orthodontic arch wire, which may cause the lock piece to be irritated. oral mucosa

When the doctor puts the orthodontic archwire into the archwire slot of the self-locking bracket and removes it from the archwire slot of the self-ligating bracket, the locking plate of the self-locking bracket covers the archwire slot due to gravity, which makes the operation inconvenient , poor oral hygiene in patients using self-ligating brackets
