Description

Tooth traction appliance

Technical Field

The utility model belongs to the technical field of oral medical instrument, concretely relates to tooth pulls and rescues ware.

Background

With the development and progress of the society, in the department of stomatology, the buried impacted teeth, the low dislocation position teeth and the subgingival broken root (hereinafter referred to as target teeth) all need to be pulled to reach the ideal position. One of the most important aspects of clinical treatment is to use a rational method to achieve both the desired position of the target tooth and to minimize the change in position of the anchorage tooth (the adjacent tooth that is used to support the counteracting force against the movement of the target tooth). The traditional method for moving the target tooth is to realize the movement of the target tooth by adopting a method that an arch wire ligated in an orthodontic fixed appliance (namely an orthodontic bracket) deforms to generate traction force, and comprises the following specific steps: firstly, the orthodontic fixing appliance (namely bracket) is bonded on the acid-etched target tooth and all the anchorage teeth one by one, then the orthodontic arch wire is ligated on the orthodontic bracket, and finally the target tooth is pulled by the traction force generated after the arch wire ligated on the orthodontic bracket is deformed, thereby gradually realizing the movement until reaching the ideal position. The problems that exist at present will now be described in detail separately as follows: 1. a plurality of healthy anchorage teeth need to be etched by acid, and later healthy tooth enamel surface demineralization, discoloration, dentin hypersensitivity and the like can occur. 2. The correcting device is fixed in the oral cavity, the patient can not take and wear the device by himself, the oral cavity is difficult to maintain in a sanitary way, the food intake is limited, and the comfort of the patient is obviously reduced. 3. Because the force is generated by the deformation of the arch wire, the magnitude of the force applied by the arch wire is not easy to control. 4. The orthodontic device is fixed on the surface of the teeth, particularly in the front tooth American area, and the oral cavity of a patient obviously sees the existence of the orthodontic device all the time in the orthodontic process, thereby influencing the beauty. 5. The traditional fixed correction method has few options of the anchorage tooth, so the anchorage tooth adjacent to the anchorage tooth is easy to lose anchorage (the adjacent anchorage tooth has position shift which is not wanted to be seen clinically). 6. The method has the defects that the resin bonded on the tooth surface cannot be completely ground and is easy to damage the healthy tooth surface, so that technical personnel in the field strive to develop a tooth movement correction appliance which is easy to master by a doctor, easy to popularize quickly and comfortable and attractive to wear by a patient.
