Tooth traction appliance

Abstract

The invention discloses a tooth traction appliance. The tooth traction appliance comprises a retractor retention plate, a buckle plate, rubber traction rings and a retention device, wherein the retractor retention plate is provided with a cavity, the cavity is provided with the buckle plate, the upper part of the cavity is provided with a buckle plate retention hole, the lower part of the buckle plate is provided with a buckle plate retention nail, the buckle plate retention nail is connected with the buckle plate retention hole in a nested mode, and the cavity is connected with the buckle plate; rubber ring leading-in holes are formed in the middle of the buckle plate, and rubber ring threading holes are formed in the position, corresponding to the tractor retention plate, of the rubber ring leading-in holes; rubber traction ring hooks are symmetrically arranged on the two sides of each rubber ring leading-in hole; one ends of the rubber traction rings are fixed on the rubber traction ring hooks, and the other ends of the rubber traction rings penetrate through the rubber ring leading-in holes and the rubber ring threading holes to be connected with the retention device on corresponding target teeth. The tooth traction appliance is simple in structure, can be picked off during feeding, and can be used after being cleaned and disinfected; the occurrence rate of gingivitis and periodontitis caused by oral hygiene of a traditional fixed appliance is reduced, and the tooth traction appliance is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of oral medical devices, and in particular relates to a tooth traction appliance. Background technique [0002] With the development and progress of society, in the Department of Stomatology, impacted teeth, low-positioned teeth and broken roots located under the gums (hereinafter referred to as target teeth) all need to use traction to reach the ideal position. In the process of clinical treatment, the most important link is to adopt a reasonable method to achieve the ideal position of the target tooth and minimize the anchorage teeth (used to support the vicinity of the reaction force against the movement of the target tooth) teeth) position changes. Traditionally, the movement of the target tooth is achieved by the deformation of the archwire tied in the orthodontic fixed appliance (that is, the orthodontic bracket) to generate traction. The specific method is as follows: first, the orthodontic fixed app...

AI Technical Summary

Problems solved by technology

The current existing problems are described in detail as follows: 1. Multiple healthy anchorage teeth need to be acid-etched, and demineralization, discoloration, and hypersensitivity of the enamel of healthy teeth will occur later.

2. The orthodontic device is fixed in the oral cavity, and the patient cannot take it off and wear it by himself. It is difficult to maintain oral hygiene, eating is restricted, and the comfort of the patient is significantly reduced.

3. Because the force is generated by the deformation of the arch wire, the magnitude of the added force is not easy to control

4. The orthodontic device is fixed on the surface of the teeth, especially in the aesthetic area of ​​the anterior teeth. During the orthodontic process, it is obvious that the orthodontic appliance always exists in the oral cavity of the patient, which affects the appearance

5. The traditional fixed orthodontic method has few options for anchorage teeth, so the adjacent anchorage teeth are prone to loss of anchorage (the adjacent anchorage teeth have clinically unwilling to see the position shift)

6. It is very difficult to remove the resin used to fix the brackets bonded to the tooth surface. The conventional method is to remove it by grinding. The disadvantage of this method is that the resin bonded to the tooth surface cannot be completely removed, and it is very difficult to remove it. It is easy to damage the healthy tooth surface. Therefore, those skilled in the art are committed to developing a tooth movement orthodontic device that is easy to be grasped by doctors, easy to be quickly promoted, and at the same time comfortable and beautiful for patients to wear.
