Novel self-locking bracket for orthodontics

Abstract

The invention discloses a novel self-locking bracket for orthodontics. The self-locking bracket comprises a net bottom, a main bracket body, a cover piece, a draw hook and elastic columns, wherein thenet bottom and the draw hook are welded on the main bracket body, the cover piece slides on the main bracket body, a spring piece is welded on the contact surface of the cover piece and the main bracket body, one end of the spring piece keeps a certain interval from the cover piece, the cover piece drives the spring piece to move synchronously, the elastic columns are mounted between the cover piece and the main bracket body, two ends of each elastic column are fixed on the cover piece and in the corresponding elastic column mounting hole respectively, a bracket is arranged on the main bracket body, and an arch wire is arranged in the bracket. Passive self-locking of the arch wire by the cover piece is completed by elasticity of the elastic columns, active self-locking of the arch wire iscompleted by mounting completion of the spring piece, automatic self-locking is realized, the cover piece after self-locking cannot get loose or fall, and the structure is stable.

Description

technical field [0001] The invention relates to a novel self-locking bracket used for orthodontics. Background technique [0002] Teeth are an important part of the human body, and dental health affects people's lives; especially for those who love beauty, a pair of beautiful and tidy teeth can increase the external beauty, improve personal temperament and self-confidence; however, teeth are affected during the growth process. The influence of a variety of external environments makes the arrangement of the teeth not neat enough, and there is a phenomenon of crookedness; in order to solve this problem, people usually correct the position of the teeth by wearing dental brackets for a long time, so that the teeth are arranged neatly; During the installation of the bracket, the orthodontic force on the teeth is formed through the adjustment of the arch wire and the bracket, so that the teeth move slowly in three dimensions and are finally arranged neatly; the bracket needs to be...

[0002] Teeth are an important part of the human body, and dental health affects people's lives; especially for those who love beauty, a pair of beautiful and tidy teeth can increase the external beauty, improve personal temperament and self-confidence; however, teeth are affected during the growth process. The influence of a variety of external environments makes the arrangement of the teeth not neat enough, and there is a phenomenon of crookedness; in order to solve this problem, people usually correct the position of the teeth by wearing dental brackets for a long time, so that the teeth are arranged neatly; During the installation of the bracket, the orthodontic force on the teeth is formed through the adjustment of the arch wire and the bracket, so that the teeth move slowly in three dimensions and are finally arranged neatly; the bracket needs to be fixed during the installation of the bracket to prevent the Slot separation; usually a cover is installed on the bracket to limit the position of the arch wire. The existing self-locking method of the cover is realized by squeezing and occluding. This fixing method of the cover is long-term use It is easy for the cover sheet to loosen and fall off, which will lead to the separation of the arch wire and the bracket. The arch wire and the bracket cannot produce orthodontic force on the teeth, making it difficult to achieve the expected orthodontic effect and affect the implementation of the normal orthodontic plan
