Design method and production method of orthodontic brace

Abstract

The invention provides a design method of an orthodontic brace. The design method of the orthodontic brace comprises the following steps: acquiring an initial digital dental model; designing a digitalupper palatal arch model with characteristic information; and generating a digital dental model with the digital upper palatal arch model, and designing the orthodontic brace. The characteristic information comprises size information of the digital upper palatal arch model and preset position information, and the preset position information of an upper palatal arch is that two ends of the upper palatal arch are arranged in positions of lingual gingiva margins in a backteeth area of the initial digital dental model or positions, close to the gingival margins, on lingual sides in the backteetharea of the initial digital dental model so that when the orthodontic brace acts on teeth, the upper palatal arch can induce buccolingual lateral amplification of maxillary palatal suture bone deposition through deformation, and the teeth in the backteeth area conduct buccolingual lateral movements under the action of the orthodontic brace. A production method of the orthodontic brace is further provided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a design method and a preparation method of a dental orthodontic device. Background technique [0002] Among orthodontists, crowding is a common clinical manifestation, although the current commonly used orthodontic design is tooth extraction, proximal surface deglazing, pushing molars to distal or labially tilting teeth to provide space. But there are still some users, the crowding is mainly manifested as insufficient dental arch width, and the crowding will be improved after the dental arch width is opened. Bow expansion treatment is a common treatment method for dental arch width adjustment. Common expansion methods include fixed expansion device expansion, four-eye spring expansion, knight expansion, implant-assisted expansion, surgical operation-assisted expansion, etc. . Invisible aligners also have a certain ability to expand the arch. Previous studies have shown...

[0003] However, most of the above treatment methods are fixed treatment methods, which not only cause great damage to the user's oral cavity, but also make the user's experience and comfort poor.

In addition, during the operation of the above correction process, it is necessary for the user to insert the wrench into the small hole of the intraoral device to perform the bow expansion operation, which greatly increases the inconvenience of the user's bow expansion, and it is also easy for the small wrench to fall into the mouth during operation. Risk of airway obstruction in the mouth

Traditional four-eye spring expanders often cause discomfort to users because their metal parts are easy to compress mucous membranes

Invisible orthodontic appliances are chosen by more and more people because they are comfortable to wear, detachable, and beautiful. Invisible orthodontic appliances themselves also have a partial arch expansion effect, but due to the small arch expansion force, the arch expansion effect is poor. The molars should be expanded forward and backward in order to prolong the expansion cycle
