Forward molar erector for bilateral force system

Abstract

The invention provides a forward molar erector for a bilateral force system. The forward molar erector comprises a double-band retainer stent, a three-section type auxiliary arch spring thrust system and a free bar tension system, wherein the double-band retainer stent comprises an affected side band, an opposite side band, a connecting lingual bar, a buccal side tube and a lingual side tube; the free bar tension system comprises a tension bar, a diamond bend, a push spring, a multi-finger traction head, a tension chain loop, a mushroom fastener I and a ligating arch wire. According to the forward molar erector disclosed by the invention, anchorage implant does not need to serve as a supporting point of orthopedic force under the condition that the orthopedic acting force is sufficient, a wound produced by use of the anchorage implant can be avoided, pain of patients is relieved, and the wound recovery time is avoided. According to the forward molar erector disclosed by the invention, the bilateral force formed by combining the thrust and tension is respectively provided for forward impacted molar, orthodontic treatment of the forward impacted molar is realized, the orthodontic treatment time is effectively shortened, the forward molar erector is convenient to adjust, and the orthodontic treatment effect is achieved.

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.
