AI Technical Summary

Technical Problem

Existing orthodontic traction and fixation devices are prone to problems during wear, such as adhesion failure, unstable traction force, insecure fixation, and discomfort. They also lack effective limiting and support structures, leading to poor treatment results.

Method used

An orthodontic corner traction and fixing device was designed, which includes a corner puller, a hanging mechanism, and a locking component. The device utilizes a crescent-shaped structure to fit the corner of the mouth, combined with the support of the ear and neck hangers. Through structures such as the clamp, positioning post, guide groove, and anti-slip pad, the device achieves stable connection and adjustment of the traction belt, ensuring the accuracy and stability of the traction force direction and angle.

Benefits of technology

It improves the accuracy of traction positioning and the controllability of treatment effects, enhances the continuity and safety of traction force, improves the comfort and stability of wearing, and solves the problems of insecure fixation, slippage and pressure caused by traditional devices.

Abstract

This utility model discloses an orthodontic corner traction and fixation device, belonging to the field of orthodontic auxiliary technology. The device includes a corner traction component and a hanging mechanism. The corner traction component, consisting of a crescent-shaped side plate, a base plate, and a top plate, securely covers the corner of the mouth. The top plate has a locking structure that can be inserted into the locking groove at the end of the traction strap for a stable connection. The hanging mechanism includes ear hooks and neck hooks. The ear hooks are used to hook onto the ears, and the neck hooks provide auxiliary support around the neck. The traction strap connects the corner traction component and the ear hooks, with its end inserted into the groove of the ear hook and wrapped around the positioning post. Guide grooves are provided on both sides of the ear hooks, and a locking component with a guide post and anti-slip pad is installed inside for sliding positioning and locking of the traction strap. This device has a clear traction path, is easy to adjust, comfortable to wear, and possesses good traction stability and orthodontic auxiliary effect.
