Problems solved by technology

[0003] In 2010, Aldoo Macchi proposed the lingual double round wire bracket. The biggest feature of this technology is that it can reduce the orthodontic force, but the disadvantage is that it can only align the front teeth and cannot be used for tooth extraction cases.

Abstract

The invention provides a three-groove bracket correction device and a tooth correction method and relates to the technical field of dental orthodontics. The three-groove bracket correction device comprises a bottom plate, at least one bracket body, a first ligature wing and a second ligature wing, wherein the at least one bracket body is arranged on the bottom plate and extends in the direction away from the bottom plate, and a main groove is formed in the bracket body. The three-groove bracket correction device can be used for correcting teeth and can effectively reduce the risk of dental root resorption in a tooth correction process, meanwhile, the problem that root control is not in place due to clearance between a rectangular wire and grooves is solved, and by means of the ligature wings, a round wire can be accommodated to realize double-wire correction.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to a three-groove bracket orthodontic device and a tooth orthodontic method. Background technique [0002] Root resorption is one of the common complications of orthodontic treatment. Orthodontic root resorption is an inevitable phenomenon accompanying orthodontic treatment. Since the incidence of root resorption after orthodontic treatment is as high as 20%-80%, it has become an urgent problem to be solved. . The root cause of root resorption in orthodontic treatment is related to the excessive concentration of apical stress during orthodontic treatment. At present, it is recognized that the root tip of the tooth is under the greatest stress during root control (torque) movement. The traditional straight wire arch correction technology needs to use a thicker square wire for root control. Excessive correction force during root control is the most important reason for root tip ...
