Embodiment Construction

[0046] The present invention will be further described below through examples and in conjunction with the accompanying drawings, but it is not intended to limit the invention.

[0047] exist figure 1 , 2 In the structure shown, the three-slot variable crown angle straight wire arch bracket designed by the present invention includes a bracket body 1, and the bracket body is respectively provided with an incisal bracket wing 3 and a gingival bracket wing 5, which are used for To correct the ligation of the arch wire, the bracket body is provided with a horizontal groove 4 (the middle groove, the position of which is the same as the groove position of the traditional bracket). The data is consistent, the two side walls of the horizontal groove are designed as full arc side walls 41, and the middle part of the side wall is convex and spreads out to the two ports, so that the two ends of the horizontal groove 4 are funnel-shaped, and the The crown angle is set from the original f...

Abstract

The invention belongs to the field of medical instruments, and relates to a three-groove variable-crown-angle straight wire arch bracket which comprises a bracket body, an incisal end bracket wing and a gingival end bracket wing are arranged on the bracket body, a horizontal groove is formed in the bracket body, an incisal end groove and a gingival end groove are formed below the incisal end bracket wing and the gingival end bracket wing respectively, and the horizontal groove is communicated with the incisal end groove and the gingival end groove. Crown angles and torque angles of the incisal end groove and the gingival end groove are the same as those of the horizontal grooves. By adopting the concept of three grooves and combining with the design of the arc-shaped groove side wall, the contact between the orthodontic arch wire and the bracket side wall is changed from linear contact to point contact, so that the friction force between the orthodontic arch wire and the bracket side wall is reduced, the common problem that the backward moving resistance of teeth is large in the existing straight wire bracket is solved, the mode of the traditional straight wire orthodontic technology is changed, and the orthodontic effect of the orthodontic arch bracket is improved. Correcting control is more accurate, moving resistance is small, moving speed is high, and the correcting treatment course is effectively shortened.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an oral orthodontic component, in particular to a three-slot variable-crown-angle straight wire arch bracket used for fixing an appliance. Background technique [0002] In the orthodontic industry, fixed appliances are the most widely used appliances, which are mainly composed of brackets, belt rings, orthodontic wires, buccal tubes and accessories. Among them, straight wire appliances are the most widely used appliances today. Wide range of appliances. [0003] Straight wire orthodontic technology was born in the 1970s, developed in the 1980s, and matured in the 1990s. In the process of development, many innovations and deformations have been carried out mainly for brackets, and many different systems have emerged, with a variety of different structural forms. The more representative ones are Anderws, Roth, MBT, etc., which are called the first. The second generation straight wire...
