Orthosis for jaw leveling

Abstract

The invention belongs to the technical field of dental medical instruments, and particularly relates to a jaw leveling orthosis which comprises an upper jaw orthosis and a lower jaw orthosis, and the upper jaw orthosis comprises a first linked crown, a second linked crown and a molar distalization device; the first linked crown is mounted on a first molar and a second molar on the same side of the upper jaw; the second united crown is mounted on a second bicuspid, a first bicuspid, canine, lateral incisor and central incisor on the same side of the upper jaw; the first linked crown and the second linked crown are mounted on the left side and the right side of the upper jaw; the molar distalization device comprises a fixing ring, a traction ring, a positioning ring, a boosting bolt and a rubber ring. According to the orthodontic device, the design is scientific, the orthodontic force can be increased by utilizing the boosting bolt according to the orthodontic requirements, then the molar is pushed backwards, a gap is obtained, and the purposes of not extracting teeth (double tips), not removing glaze, not hitting anchorage nails and orthodontic Angle I, II and III functional malocclusion are achieved. The device has the advantages of multiple functions, wide application and low cost, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the technical field of dental medical instruments, and in particular relates to a jaw flat orthosis. Background technique [0002] Distant displacement of molars in adults is a difficult problem in orthodontic work. In the development history of orthodontics, for intraoral fixation, the first molar band was initially used, and the extraoral traction method was used to correct the receding molars in adolescence. In the middle of the year, Greenfield invented the fixed piston appliance. More recently, molar thrusters have been used. [0003] However, the wearing of extraoral anchorage is complicated and difficult for patients to accept. Fixed piston appliances and recent molar pushers often have problems of insufficient anchorage and difficulty in pushing molars far away during use, which cannot meet the requirements of orthodontic treatment, especially when anchorage teeth are missing or loose. In order to overcome the probl...

Problems solved by technology

[0003] However, wearing extraoral anchorage is complicated and difficult for patients to accept

Fixed piston appliances and recent molar pushers often have problems of insufficient anchorage and difficulty in pushing the molars away during use, which cannot meet the requirements of orthodontic treatment, especially when the anchorage teeth are missing or loose

In order to overcome the problem of insufficient anchorage, anchorage screws are often used clinically to strengthen anchorage, but the use of anchorage screws increases the cost of treatment, and the side effects of anchorage screws are relatively large, often causing gingival pain and discomfort
