Embodiment Construction
[0024] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings, but this patent is not limited to these embodiments.
[0025] The present invention is a personalized bottom plate lingual bracket for orthodontics. The bracket includes a base plate 2 structural part and a bracket body 1 part with an archwire groove on the base plate. The base plate part is designed according to the shape of the lingual surface of the patient’s teeth through computer three-dimensional software, and a personalized base plate plus a guide rod structure is produced by 3D printing; the bracket body part is cast by injecting high-pressure metal powder into the mold, including brackets The slot connection part 6, the archwire groove part 5, the first working wing 3 and the second working wing 4, the first and second working wings are respectively located on both sides of the archwire groove, and the archwire groove 5 is Vertically o...

The invention discloses a method for preparing an inserting type personalized tongue-side orthodontic bracket. The method comprises the following steps: building a three-dimensional model of a bracket body; building a three-dimensional model of a base plate; selecting a positioning groove positioned on a certain place of the bottom of the bracket body in a virtual combination of three-dimensional computer software of the bracket body and the base plate; determining a space position relation between a guiding rod and the base plate according to the direction of the positioning groove, and simultaneously increasing a three-dimensional model of the guiding rod through the three-dimensional computer software in the three-dimensional model of the base plate according to the determined space positioning relation; assembling the prepared bracket body and the base plate together to obtain the personalized tongue-side orthodontic bracket. According to the method, an integral casting or integral printing mode of the traditional personalized tongue-side bracket is changed into a mode that a groove ditch part of the bracket plays a role in casting, the base plate part of the bracket plays a role in 3D printing, and finally, both of the two parts are inserted with one other and are welded and molded, so that the manufacturing cost is reduced; meanwhile, a combination angle of the bracket body and the base plate part is more accurate.
Description
technical field [0001] The invention relates to the field of orthodontics, in particular to a spliced-in personalized orthodontic bracket. Background technique [0002] In orthodontic treatment, more and more adults not only pursue the "beauty of results" of orthodontics, but also require "beauty of process" in the process of orthodontic treatment. Lingual orthodontic treatment means that the brackets that control the movement of the teeth are bonded to the lingual side of the patient's teeth, so that the lip side is truly invisible. Therefore, lingual brackets are currently receiving extensive attention and research. At present, lingual brackets can be mainly divided into the following three categories: 1. Non-personalized lingual brackets. Because the bottom plate of this type of bracket is not personalized, it is usually difficult to completely match the lingual surface of the patient's teeth, which is likely to bring adverse effects on the treatment. 2. Casting persona...
