Traction device for mandibular impacted wisdom teeth

Abstract

The invention provides a traction device for mandibular impacted wisdom teeth, which relates to the field of orthodontics. The device comprises a bracket, a first retention part, a second retention part and a traction part, wherein the bracket is used for being fixed on the lingual sides of mandibular first and second molars on the same side of a mandibular impacted wisdom tooth, the first retention part is used for being fixed on the crown side of the mandibular impacted wisdom tooth, the second retention part is used for being fixed on the buccal side of the mandibular impacted wisdom tooth, and the two ends of the traction part are respectively connected with the bracket and the first retention part; and the bracket comprises a rod-shaped main body, connecting heads, a connecting rod and a cross rod, the connecting heads are respectively arranged at the positions on the rod-shaped main body and corresponding to the mandibular first and second molars, a groove and the cross rod are arranged at the positions on the rod-shaped main body and corresponding to the mandibular impacted wisdom tooth, the cross rod and the rod-shaped main body are parallel to each other and are located on the occlusion side of the rod-shaped main body, and the cross rod is connected with the rod-shaped main body by the connecting rod. The traction device provided by the invention can flexibly adjust the traction direction of an impacted wisdom tooth, and effectively draw the impacted wisdom tooth to separate from an alveolar nerve canal in a relatively short period of time so as to facilitate subsequent tooth extraction treatment.

Description

technical field [0001] The invention relates to the field of orthodontic instruments, in particular to a traction device for mandibular impacted wisdom teeth. Background technique [0002] In oral clinic, pericoronitis of mandibular impacted wisdom teeth is relatively common. If such patients have recurrent pericoronitis, extraction of the impacted wisdom tooth is often considered. However, if the mandibular wisdom tooth to be extracted is closely adjacent to the inferior alveolar canal, direct The extraction of impacted wisdom teeth may damage the alveolar nerve canal, cause lower lip numbness, and significantly affect the quality of life of patients. A better way to solve this problem is to combine orthodontic treatment first, and remove the wisdom teeth from the inferior alveolar canal through orthodontic traction, and then extract them. However, the existing orthodontic methods have narrow indications and a long course of treatment. Contents of the invention [0003] ...
