Horizontal high impacted central incisor traction device

Abstract

The invention provides a horizontal high impacted central incisor traction device which comprises a traction splint, a fixed appliance and an orthodontic elastic traction piece, the side edge of the traction splint is provided with a notch part used for being bonded and clamped on the labio-lingual side tooth surface of a central incisor needing to be corrected, the notch part is matched with the labio-lingual side tooth surface of the central incisor in shape; the contact surface between the traction splint and the mucous membrane on the inner side of the upper lip is a flat smooth cambered surface, a plurality of traction holes are formed in the traction splint in the flat smooth cambered surface from the lingual side to the labial side, the fixed appliance is adhered and fixed on natural teeth adjacent to impacted central incisor teeth, a main arch wire of the fixed appliance is fixedly connected with a traction hook, one end of the orthodontic elastic traction piece is hooked with the traction hook, and the other end of the orthodontic elastic traction piece is sequentially wound with each traction hole in the lingual and labial sides of the traction splint along with downward movement of the central incisor tooth crown. The size and direction of traction force can be changed by gradually adjusting the connection positions of the orthodontic elastic traction piece and the traction points where the traction holes in the traction splint are located, operation is easy, and the comfort level of a patient can be improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a traction device for horizontal high-position impacted central incisors. Background technique [0002] Impacted teeth are a common clinical disease in orthodontics, especially the high incidence of impacted maxillary central incisors in the population. Impacted teeth can cause dental arch deformities, affecting the patient's masticatory function and facial appearance. Therefore, the treatment of impacted teeth is very necessary for both health and aesthetics. The orthodontic treatment of impacted central incisors is mainly fenestration and traction to aid eruption, including surgical fenestration to expose the crown of the impacted central incisor, bonding accessories on the labial surface of the crown of the impacted central incisor, and cooperating with traction to apply force. The device pulls the impacted central incisors to erupt from the alveolar bone, thereby aligning th...

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
