[0036] When the patient bites, the patient's lower jaw gradually moves backward to the set position under the guidance of the inclined guide plate 2. Through long-term wearing, the lower jaw will adapt to the new rest position and be fixed to achieve auxiliary correction of the upper and lower jaw position relationship. The operation is simple, while reducing the risk of overcorrection and having high reliability.
[0037] Specifically, the overall shape of the braces 1 is prepared according to the patient's tooth model, and the braces 1 fits firmly on the surface of the patient's lower teeth. The braces 1 includes an inner ring 11 and an outer ring 12. The inner ring 11 is located on the inner side of the lower teeth, and the outer ring 12 is located on the outer side of the lower teeth. The thickness of the inner ring 11 is 1.5-2mm. Since the inner ring 11 is close to the inner side of the mouth, there is a large space, and it is not easy to produce a foreign body sensation when worn. The 1.5-2mm thick inner ring 11 has high structural strength and is not easy to deform, which can play a major supporting and retaining role. The thickness of the outer ring 12 is 0.5-1mm, which is thinner and helps to improve the wearing comfort. At the same time, the 0.5-1mm thick outer ring 12 can be bent and deformed, which is convenient for wearing. The inner ring 11 pulls and fixes the outer ring 12, so that the braces can correct and fix the position of the patient's teeth without the assistance of wires or other devices.
[0038] The bevel guide plate 2 includes an inserting surface 21, a connecting surface 22, and a leading bevel 23. The inserting surface 21 is located at the bottom end of the bevel guide plate 2 and is used for inserting and mating the bevel guide plate 2 with the braces 1.
