Method for correcting class II occlusion malformation

Abstract

The embodiment of the invention discloses a bony class-II malformation correction method which comprises the following steps: quickly aligning teeth by adopting a multi-effect nickel-titanium arch wire, adducting anterior teeth by utilizing an anchorage nail and a constant-force tension spring, distally erecting upper posterior teeth, leveling a lower jaw spee curve, rotating a mandible anticlockwise, stretching a mandible chin forwards, reducing the heights of the upper posterior teeth and the lower posterior teeth, and promoting the mandible to rotate anticlockwise. And the lower anterior teeth are erected on the basal bone and are simultaneously depressed. In the later treatment period, when the upper anterior teeth reach the standard position, the lower mandibular anterior teeth are fully erected in the basal bone, but the anterior teeth cover a large area, a TMA wire is used for bending and raising in cooperation with oblique guiding and (or) the lower mandibular to conduct short-distance II-type traction, a rear tooth occlusion relation is established, the lower mandibular bone is promoted to move forwards, and the face of a II-type patient is improved. According to the invention, complicated operations such as operations are not needed, the orthopedic II-type correction of adults can be completed, and the facial forms of maxillary protrusion and mandibular retrograde can be effectively improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of orthodontics, in particular to a type II malocclusion Methods of deformity correction. Background technique [0002] Skeletal malocclusion mainly refers to the problem of tooth deformity caused by the influence of genetic factors and acquired factors in the growth process. When it comes to the shape and position, there will be problems such as facial deformity, which will seriously affect the external image. Class II 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 skeletal class II malocclusion Deformity correction method to solve skeletal class II malocclusion in the prior art Difficult problems in deformity correction. [0004] In order...
