Customized lingual side fixed retainer and preparation method thereof

Abstract

The invention discloses a customized lingual side fixed retainer which can provide continuous and stable retentiveness, shorten a patient treatment cycle and realize personalized treatment, and a preparation method thereof; the customized lingual side fixed retainer includes a fixed retainer main body which is molded by one time through three-dimensional stereoscopic printing, and the fixed retainer main body is made of an alloy material, and is pasted and fixed with patient teeth through resin. The invention provides the customized lingual side fixed retainer and the preparation method thereof; the customized lingual side fixed retainer made of the alloy material having a shape memory function has a personalized shape matched with arraying of patient own teeth; through self positioning with a fixed retaining structure which is safely fitted to the hook shape of the surface of each tooth, fast pasting is achieved, an indirect pasting guide plate for positioning has no need of additional design, and the difficulty and intensity of doctor clinical operation are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a custom-made lingual fixation retainer and a manufacturing method thereof. Background technique [0002] Oral fixed retainer is aimed at teeth that need to be worn for a long time after orthodontic treatment to maintain the therapeutic effect. It mainly uses a retainer composed of arch wire and resin to apply mechanical retaining force and torque to the teeth; Maintain orthodontic treatment effect after maintenance. [0003] At present, the application of arch wire and resin support to fix the retainer has become the mainstream technology of oral machine. The key is to use the arch wire and resin with specific parameters corresponding to different tooth positions to maintain the size between each tooth and the occlusal line difference. Our country did not introduce the technology of removable retainer until the 1980s. There are only hundreds of thousands of orthodontic...

Problems solved by technology

The recently developed guide plate for indirect bonding of brackets through computational aided design and 3D printing can help doctors quickly find the correct position of the tooth surface on the brackets, greatly reducing the labor intensity of doctors, but the design process is complicated and the accuracy Difficult to guarantee

However, during the course of one to two years of correction, patients need to return for regular return visits to replace the arch wire, causing inconvenience to patients and increasing treatment costs
