Description

Impacted molar upright device

Technical Field

The utility model belongs to the technical field of oral cavity orthopedic equipment, and particularly relates to a impacted molar erecting device.

Background

The primary function of molars is to chew food, and loss of molars will directly affect the chewing function. In clinic, the first lower molar is not cleaned in time or not in place due to the earliest eruption, more pit gaps and fissure gaps, and the patient is younger in age, so that the caries rate is higher. The investigation and research on the tooth loss of children and young people in different age groups shows that the first molar loss rate is the highest and exceeds 30%, and the second molar loss rate of the lower jaw is about 20%. The loss of the lower jaw molars not only causes the reduction of chewing efficiency, but also easily causes a series of problems of tooth jaw extension, adjacent tooth inclination to the gap of the missing teeth and the like.

In the prior art, the method for repairing the mandibular molar loss mainly comprises fixed bridge repair, removable partial denture repair, implant repair and autologous tooth transplantation. Although the chewing function of a patient can be recovered in a short time by adopting the rehabilitation therapy, the long-term treatment effect is poor, and various rehabilitation problems exist.

Meanwhile, clinically, molar occlusion is a serious malocclusion phenomenon. The most common molar occlusion is that of the third molar, with an occlusion rate of up to 69%, with the occlusion rate of the lower third molar being 31% and most common in all types of molar occlusions, near middle molar. The existing vertical near-middle impacted molar technology comprises the steps of implanting a nail to assist vertical impacted molar or removing bones through surgical operation, exposing the buccal surface of the impacted molar and applying force to the vertical impacted molar from the buccal side, wherein certain trauma exists in the two modes.

Based on the above, the upright third molar which is used for replacing the missing first molar or second molar becomes an important way for shaping the malocclusion of the molar. In the existing vertical mode of molar, the mode of implant nail traction, retroversion bending, molar ring welding of a multi-curve arch wire and the like are mostly adopted, and the problem of wound or complex operation exists.

In order to solve the above problems, the inventors have devised an upright device for impacted third molar for correction of the third molar which can correct both impacted third molar and loss of molar.
