Individual lingual bracket appliance and manufacture method thereof

Abstract

The invention relates to an individual lingual bracket appliance and a manufacture method thereof. The method comprises the following steps of: (1) acquiring a digital dentition model; (2) putting a bracket body and a connecting body of the tooth position to the middle of the corresponding tooth lingual side along the track and plane of an arch wire; (3) selecting a long towing hook or short towing hook when a bracket is designed in CAD software, rotating the towing hook to enable the towing hook to be far away from gum; (4) outputting in a STL format and printing to form a wax pattern; (5) embedding the wax pattern, casting a metal part, and assembling the parts to form a complete bracket or molar lingual pipe; (6) manufacturing an individual bracket placement gauge; and (7) drawing an arch wire according to a lingual arch diagram selected during tooth arrangement by a computer, and assembling the arch wire with the individual bracket placement gauge. The operation method is simple and convenient and has high production efficiency, and the manufactured appliance has accurate positioning and excellent treatment effect.

Description

technical field [0001] The invention relates to the field of orthodontic bracket manufacturing, in particular to a personalized lingual bracket appliance and a manufacturing method thereof. Background technique [0002] With the development of orthodontic technology and the gradual improvement of people's requirements for aesthetics, lingual invisible orthodontics has gradually become a hot spot in orthodontics. In traditional labial orthodontics, because the brackets are located on the labial side of the teeth, it affects the aesthetics of patients, so many people give up orthodontic treatment. The lingual bracket appliance is located on the lingual side of the teeth, which can truly be completely invisible, meeting the needs of many adult patients with high aesthetic requirements. [0003] However, due to the great difference in the shape of the lingual surface of each person's teeth, traditional lingual appliances are made by hand-made plaster models, and resin needs to ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the great difference in the shape of the lingual surface of each person's teeth, traditional lingual appliances are made by hand-made plaster models, and resin needs to be filled between the bracket base plate and the tooth surface to form a personalized base plate, which is also relatively thick. The control of the arch wire on the tooth body and the comfort of the tongue body are poor, and the production in the laboratory is more troublesome, and it is easy to fall off. Once it falls off, it is difficult to bond again

In addition, the length and position of the traditional lingual brackets often cause discomfort in the patient's tongue and affect the patient's pronunciation, which is also a major reason why patients give up lingual treatment.
