Abstract

The invention discloses a bracket-free invisible orthodontic vertical control device used after an orthognathic operation. The device comprises an upper jaw appliance, a lower jaw appliance and a plurality of cushion blocks; and the plurality of cushion blocks are positioned on the opposite sides of the upper jaw appliance and the lower jaw appliance, so that an occlusion gap is formed between the upper jaw appliance and the lower jaw appliance. At least one cushion block is provided with a correction guide structure in the occlusion direction, and the correction guide structure is used for keeping the upper jaw appliance and the lower jaw appliance at preset relative positions in an occlusion state. On one hand, direct contact between the upper jaw appliance and the lower jaw appliance can be blocked by arranging the cushion blocks, so that instable occlusion of upper and lower jawbones due to fulcrum tilting formed by contact of individual teeth is avoided; and on the other hand, when the upper and lower dentitions are in the rest position, the upper and lower occlusion relationship is unique, so that the influence on the jaw stability due to local stress application of the appliance to the teeth is reduced. In addition, during use, small displacement of the upper and lower jawbones due to intermaxillary traction can be avoided, and the aim of consolidating the orthognathic treatment effect is achieved.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a vertical control device for invisible correction without brackets after orthognathic surgery. Background technique

[0002] Bracketless invisible aligner is a computer-aided design and production of transparent elastic material movable orthodontic device. It is a series of continuous orthodontic devices, and achieves the purpose of orthodontics through continuous small-scale tooth movement. The appliance can not only control the size of the corrective force, but also control the time of the corrective force. In different stages, only certain teeth can be moved, while other teeth are used as anchorages to complete the correction of the teeth.

[0003] In the prior art, auxiliary orthodontic treatment is required after orthognathic surgery. The orthodontic treatment at this stage has the following difficulties: 1. After the jaw is broken, it is in the process of fixed he...
