Problems solved by technology

The belt ring is easy to loosen, and it is also easy to shift during the movement of the canines, which affects the effect of the canine movement; the welding between the traction device and the belt ring is easy to cause desoldering, and the traction device is not strong enough, which will affect the movement of the canines. Easily deformed during the process
Therefore,

Embodiment Construction

[0024] The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings.

[0025] see Figure 1~2 , the present invention includes two pairs of corresponding canine crowns 1 and molar crowns 3, the palatal sides of the two molar crowns 3 are connected by a palatal bar 4, the molar crowns 3 and the palatal bar 4 are integrally cast, and the two traction The device 2 is laser welded on the buccal side of each pair of canine crowns 1 and molar crowns 3 respectively, and the laser welding positions on the canine crowns 1 and molar crowns 3 are at the same level, and the laser welding positions are preferably the canine crowns 1 and 3. Molar crown 3 median.

[0026] see image 3 , a kind of traction device of the present invention is made up of guide rod 2.1 on both sides, middle screw rod 2.2 and fixing groove 2.3 at both ends, and fixing groove 2.3 is provided with three through holes, and these three through holes ar...

Abstract

The invention discloses a retractor for rapid and distal movement of cuspids. The retractor comprises a pair of cuspid crowns and a pair of molar crowns which correspond to each other; a connecting part is connected with the palatal side of each molar crown; the molar crowns and the connecting parts are cast in an integrated manner; and a retracting device is fixed at the cheek side of each pair of cuspid crown and molar crown respectively. According to the retractor for the rapid and distal movement of the cuspids, the crowns are used for replacing bands, and the crowns and the connecting parts are cast in the integrated manner, so that the crowns and the connecting parts are connected more firmly and attached on teeth better, and the foreign body sensation in the oral cavity of a user is greatly reduced; and in addition, the crowns are used for replacing the bands, so that the crowns are unlikely to be loosened or displaced in the orthodontic process and smooth therapeutic process can be guaranteed.

Description

[0001] technical field [0002] The invention belongs to the technical field of orthodontics, and in particular relates to a retractor for rapid and distal movement of canines. Background technique [0003] The distal movement of canines is a key step in orthodontic treatment of type II malocclusion. The canine rapid distal movement retractor is a clinically applied canine distal rapid movement device based on the theory of periodontal ligament traction osteogenesis. . The theory of periodontal ligament distraction ossification holds that the periodontal ligament is similar to the bone suture between the tooth and the alveolar bone, and the periodontal ligament distraction ossification in the process of orthodontics just utilizes the similarity with the rapid expansion of the maxillary suture. The rapid traction of the periodontal ligament achieves the rapid distal movement of the canines, saves the anchorage of the posterior teeth, and does not cause adverse reactions such...
