A traction device for horizontal high impacted central incisors

Abstract

The invention provides a traction device for horizontal high-position impacted central incisors, which includes a traction splint, a fixed appliance and an orthodontic elastic traction member. The side of the traction splint is provided with a device for bonding and clamping the labial-lingual tooth surface of the central incisor that needs to be corrected. The notch is adapted to the shape of the labial and lingual tooth surface of the central incisor. The contact surface between the traction splint and the inner mucosa of the upper lip is a flat and smooth arc surface. The traction splint inside the flat and smooth arc surface is equipped with multiple A traction hole, the fixed appliance is bonded and fixed on the natural teeth adjacent to the impacted central incisor, the main arch wire of the fixed appliance is fixedly connected with a traction hook, one end of the orthodontic elastic traction piece is hooked to the traction hook, and the other end As the crown of the central incisor moves down, it is sequentially connected with each traction hole on the lingual side of the traction splint. The application can change the magnitude and direction of the traction force by gradually adjusting the connection position of the orthodontic elastic traction member and the traction point where different traction holes are located on the traction splint, the operation is simple and easy, and the comfort of the patient can be improved.

Description

Technical field [0001] The present invention relates to the field of medical devices, specifically to a horizontal high-level obstruction incisor traction device. Background [0002] Ambushed impacted teeth are a common disease in orthodontic clinics, especially the high level of impacted growth in the upper jaw middle incision teeth has a high incidence in the population. Impacted teeth can cause arch deformities, affecting the patient's chewing function and aesthetic appearance, so the correction of impacted teeth is very necessary for both health and aesthetics. The orthodontic treatment methods of ambushed obstructed middle incisors are mainly window opening and traction assistance, including surgical windowing exposure of the impacted middle incisor crown, bonding attachments on the lip side of the crown of the impacted middle incisor, and pulling the ambushed incisors with traction force devices to erupt from the alveolar bone, thereby arranging the impacted middle incisors...

Problems solved by technology

[0004] In view of the orthodontic treatment of the existing horizontal high impacted central incisors, the adhesive attachment will cause damage to the inner surface of the upper lip mucosa, and the traction point of the orthodontic elastic traction piece is not conducive to the control of the magnitude and direction of the traction force, and with the upper central incisor As the crown moves down, the traction device cannot provide the same continuous force as before, that is, it cannot provide continuous and gentle traction, and the direction of the traction is not easy to adjust, so it is often difficult to obtain better curative effect. The bonding position of the labial surface of the incisor crown can change the traction force, but due to the limitation of the fenestration and the exposed area of ​​the central incisor crown, the movement of the bonding position of the bonding attachment is also limited, and the bonding position of the bonding attachment is also limited. Moving also makes the operation more complicated and difficult, and requires more treatment time, which not only increases the doctor's workload, time-consuming and laborious, reduces the patient's comfort and increases the patient's psychological rejection, but also reduces the level of high steric resistance To solve the technical problem of the success rate of eruption aided by traction of central incisors, the present invention provides a traction device for horizontal high impacted central incisors
