Abstract

The invention discloses a design method and a preparation method of a tooth correction system. The design method comprises the following steps: acquiring feature information of a digital dental model; obtaining target correction information; designing a correction plan; the tooth correction system is designed on the basis of a digital tooth jaw model and a correction plan, the tooth correction system comprises a shell-shaped tooth correction device and an auxiliary correction device matched with the shell-shaped tooth correction device, and at least one action part is arranged on the shell-shaped tooth correction device; the acting part penetrates through the inner surface and the outer surface of the shell-shaped tooth appliance; the action part is used for allowing the top of an auxiliary correction device arranged on the surface of a tooth to penetrate outwards from the interior of a cavity of the shell-shaped tooth appliance and guiding the tooth to gradually change from an initial position to a target correction position by utilizing the interaction force of the shell-shaped tooth appliance and the auxiliary correction device. The tooth correction system obtained by the design method can improve the correction effect and shorten the correction period.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a design method and a preparation method of an orthodontic system. Background technique [0002] In recent years, in the field of orthodontics, shell-shaped orthodontic appliances using invisible orthodontic technology have become more and more popular due to their beautiful appearance and convenience when worn. In order to achieve the expected orthodontic effect, shell-shaped dental appliances sometimes need to be used in conjunction with accessories pasted on the tooth surface for orthodontic treatment. The accessories can be made of light-cured resin or directly pasted by prefabricated accessories. To assist the movement of teeth and the retention of orthodontic appliances. [0003] Existing shell-shaped dental appliances used in conjunction with accessories are usually all-inclusive appliances for accessories. Specifically, shell-shaped dental appliances are...
