Traction device, shell-shaped dental appliance with traction device, system and set

Abstract

The invention discloses a traction device, a shell-shaped dental appliance with the traction device, a system and a set appliance. The traction device comprises a traction component, wherein the traction component comprises a traction part for traction, a connecting part and a mounting part provided with a force dispersion component; the traction part is arranged at one end of the connecting part; the mounting part is arranged at the other end of the connecting part; the traction device is fixedly connected with the shell-shaped dental appliance through the mounting part; and when the traction part is pulled, the mounting part disperses the force generated by traction to the shell-shaped dental appliance through the force dispersion component. The traction device, the shell-shaped dental appliance with the traction device, the system and the set provided by the invention have small deformation and are difficult to break when pulled.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and more precisely relates to a traction device, a shell-shaped orthodontic device with the traction device, a system and a set. Background technique [0002] Traditional orthodontic techniques usually use brackets and wires to move teeth to correct malocclusion. However, such brackets and steel wires are too many and too obvious, which greatly affects the appearance, and may cause oral damage such as gingival inflammation, tooth demineralization and discoloration. On this basis, the invisible orthodontic system came into being, which uses an invisible shell-shaped orthodontic device made of elastic transparent polymer materials to realize the movement of teeth. The whole orthodontic process hardly affects daily life and social interaction. At the same time, because patients can take off and wear it by themselves, it is convenient for daily oral health maintenance, which also makes the whol...

Problems solved by technology

[0004] In the prior art, by prefabricating openings on shell-shaped orthodontics or cutting openings on shell-shaped orthodontics, the traction device is pasted on the teeth through the prefabricated opening or the traction member is directly suspended through the cut opening, but the shell-shaped teeth Prefabricated or cut openings on the aligner will destroy the structure of the shell-shaped aligner, making the fit of the aligner worse and the correction strength of the aligner insufficient

[0005] In the prior art, it is also possible to directly paste the traction device on the surface of the shell-shaped orthodontic appliance, but when the force generated during traction is concentrated and distributed on the shell-shaped orthodontic appliance, not only will the deformation of the shell-shaped orthodontic appliance be serious, It may even cause the fracture of the shell-shaped dental aligner, and the application provides a technical solution to solve the above problems
