Traction device and correction method for impacted anterior teeth

Abstract

The invention is applicable to the technical field of oral cavity correction, and provides a traction device and a correction method for impacted anterior teeth. The traction device for the impacted anterior teeth comprises a base, a first belt ring, a second belt ring and a traction hook, wherein the base is connected with one end of a first connecting rod, one end of a second connecting rod andone end of a third connecting rod; the first belt ring is connected to the other end of the first connecting rod; the second belt ring is connected to the other end of the second connecting rod; and the traction hook is connected to the other end of the third connecting rod, or the traction hook is formed by the other end of the third connecting rod. The traction device for the impacted anterior teeth is simple in structure, convenient in clinical operation and short in chair-side time; inclination of adjacent teeth and narrowing of an edentulous gap can be avoided; the traction force value ofthe impacted anterior teeth can be accurately designed, and the traction efficiency and the treatment success rate of the impacted anterior teeth are greatly improved; the device does not need to beindependently adjusted in each subsequent visit, and the comfort of a patient is improved.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a traction device and a treatment method for impacted upper anterior teeth. Background technique [0002] In recent years, the number of patients with impacted upper anterior teeth has gradually increased in orthodontic clinics. Most of these patients are 7-10 years old, and the clinical manifestations are that the normally replaced maxillary incisors do not erupt in time, and gaps occur at the eruption position, which is manifested as "missing teeth"; imaging examinations show that there are many impacted maxillary incisors It is high sagittal and horizontally impacted, and is often accompanied by abnormal root development. The root is shorter than the normal contralateral tooth of the same name, the apical foramen may not be completely closed, and the apex of the tooth is bent into an angle. For such cases of impacted upper anterior teeth in the replacement pe...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 Shown is the device in the prior art for correcting the impacted upper anterior teeth in the replacement dentition period. The device uses the adjacent teeth as anchorage. Since the patient is in the dentition replacement period, the teeth and alveolar are in the period of growth and change, and the number of adjacent teeth is not enough Form a strong anchorage to pull the impacted upper anterior teeth. Therefore, the traditional traction method of the impacted upper anterior teeth often causes the adjacent teeth to tilt, the eruption space of the impacted upper anterior teeth narrows, and even the risk of root resorption of the adjacent teeth occurs.
