Molar orthodontic device and molar erecting method

Abstract

The invention provides a molar orthodontic device and a molar erecting method. The molar orthodontic device comprises a vertical hook and a belt ring, wherein the vertical hook is used for being adhered to a first tooth, the belt ring comprises a ring body and a spring part arranged on the ring body, the ring body is used for being arranged on a second tooth adjacent to the first tooth, and the spring part is used for contacting the vertical hook to drive the belt ring away from the vertical hook. According to the molar orthodontic device, the belt ring is arranged on the second tooth, the second tooth serves as an anchorage, arrangement of an anchorage nail in the mouth can be avoided, the molar orthodontic device can reduce foreign body sensation in the mouth of a patient, a position of the vertical hook can be adjusted according to an exposure condition of the first tooth, and the molar orthodontic device is suitable for correcting high impacted first tooth, and is also suitable for correcting low impacted first teeth.

Description

technical field [0001] The invention relates to the field of molar orthodontic research, in particular to a molar orthodontic device and a molar vertical method. Background technique [0002] Clinically, the first or second molars are often unable to be preserved due to factors such as caries and fractures, while the adjacent third molars often have normal crowns and well-developed roots. However, with the refinement of human food, Tooth degeneration is later than jaw bone degeneration, and various types of impacted third molars are common in clinical practice. Studies have shown that the vertical impacted rate of third molars is 38%, the mesial impacted rate is 43%, the horizontal impacted rate is 3%, and the distal impacted rate is 6%. [0003] At present, scholars at home and abroad agree that it is feasible to replace the first or second molars with healthy second and third molars. Through this method, a complete healthy dentition can be re-established. After treatment...

AI Technical Summary

Problems solved by technology

[0006] The above devices have the following disadvantages. First, in the process of vertical third molars in the above treatment method, the third molars need to be tilted far away first, and then move to the mesial. The treatment cycle is prolonged; second, pushing the third molars or pulling the molars to the distal position will easily cause the occlusal high point in the distal part of the third molars, which will form occlusal interference with the opposing teeth

[0007] In addition, the above-mentioned treatment methods all require additional implantation of anchorage nails as anchorage. The installation of anchorage nails is an invasive operation, which will cause certain damage to the patient. The anchorage nails will also cause foreign body sensation in the patient's mouth.
