Anterior tilting molar erector with two-way force system

Abstract

The present invention provides a two-way force system forward molar erector, which includes a double-belt ring retention bracket, a three-stage auxiliary bow spring thrust system and a free rod tension system. The double-belt ring retention bracket includes a belt ring on the affected side, Side belt ring, connecting lingual bar, buccal side tube and lingual side tube; the free rod tension system includes a tension bar, a rhombus, a push spring, a multi-finger traction head, a tension chain ring, a mushroom buckle and a ligated arch wire; the present invention can Under the premise of ensuring sufficient orthodontic force, it is not necessary to use implant anchorage screws as the fulcrum of the orthodontic force, which can avoid wounds caused by the use of anchorage nails, reduce patient pain, and save wound recovery time. The present invention respectively provides two-way forces formed by the combination of thrust force and pulling force for the impacted forward molars, realizes the correction of the impacted forward molars, effectively shortens the treatment time, is convenient for adjustment, and ensures the treatment effect.

Description

technical field [0001] The invention relates to a forward tilting molar erector with a two-way force system. [0002] This work was supported by the Medical and Health Application Basic Research Project of Suzhou Science and Technology Bureau (SYS201678). Background technique [0003] Anterior molars are one of the common situations that require orthodontic treatment. Usually, forward molars will produce impaction force on adjacent molars, which is relatively harmful. Existing forward molar erectors are mainly divided into two classes at present. [0004] One is to use the anchorage screw in the jawbone as the fulcrum of the force. In this way, the force is respectively on the anchorage screw and the forward molars. During the whole orthodontic process, no force will be applied to other teeth, so as to avoid other teeth. The displacement of the tooth as the fulcrum of the force avoids adverse effects on other teeth. However, because implant anchorage screws will cause wou...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a kind of antegrade molar erector with two-way force system to solve the problem that the implant anchorage nails in the prior art will cause wounds in the oral cavity, and the patient feels great pain and takes a long time to recover. As the fulcrum of the anti-screw, there are problems such as insufficient anchorage, insufficient force, unsuitable control of the direction of the correction force, long treatment time, unsatisfactory correction effect, and inconvenient clinical adjustment of the correction force during the treatment process.
