Embodiment

[0029] like Figure 1-Figure 5 As shown, the present invention provides a kind of skeletal class III malocclusion Deformity correction method, and skeletal class III malocclusion The deformity correction method includes the following steps:

[0030] S1. In the stage of dentition alignment, use a multi-performance nickel-titanium arch wire to quickly align the teeth to remove the occlusal obstacle of the anterior teeth;

[0031] S2. After the anterior teeth are aligned, use the mandibular implant anchorage screw 2 and the fixed force tension spring 3 to retract the anterior teeth and release the anterior crossbite

[0032] S3, anterior crossbite After lifting, use TMA wire 4 steps to elevate the upper and lower posterior teeth to quickly establish the occlusal relationship of the posterior teeth and simultaneously establish normal coverage of the anterior teeth;

[0033] S4. Maintain the normal coverage of the front teeth, raise and tilt the back of the mandible clockw...

Abstract

The embodiment of the invention discloses a bony III-class malformation correction method, which comprises the following steps of: quickly aligning teeth by adopting a multi-effect nickel-titanium arch wire, retracting anterior teeth by utilizing an anchorage nail and a constant-force tension spring to remove anterior tooth reverse on the premise of removing anterior tooth occlusion disorder, and after the anterior tooth reverse is removed, lifting upper and lower posterior teeth by using a TMA wire in a step curve manner, quickly establishing a posterior tooth occlusion relationship, stabilizing a new position of retreat of a mandible, removing an anterior tooth occlusion wound, and lifting and clockwise inclining the plane of the rear part of the mandible on the premise of maintaining normal coverage of the anterior teeth so as to promote clockwise rotation of the mandible, retreat of the chin of the mandible and lip inclination of the anterior teeth, and finally adjusting the occlusion stage to observe the condition of a patient. According to the invention, the mandibular prolapse can be effectively improved, and the reverse face type can be improved, so that the non-tooth extraction correction of adult bone mandibular prolapse cases can be completed.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of orthodontics, in particular to a class III malocclusion Methods of deformity correction. Background technique [0002] bone malformation Deformity mainly refers to the problem of tooth deformity caused by the influence of genetic factors and acquired factors during the growth process. The teeth will be unevenly arranged, and there will also be problems of malocclusion, and even affect the shape and position of the mandible. There will be problems such as facial deformities, which will seriously affect the external image. Class III malocclusion is currently recognized in the orthodontic community It is one of the difficulties in orthodontic treatment, and thus lacks suitable treatment methods for treatment. Contents of the invention [0003] For this reason, the embodiment of the present invention provides a kind of skeletal class III malocclusion Deformity correction m...
