Problems solved by technology

In the traditional ligation method, the friction between the arch wire and the bracket is relatively large, which will affect the movement of the teeth
In order to improve the above situation, self-locking brackets have appeared on the market now. Although the self-locking brackets reduce the friction between the arch wire and the brackets to a certain extent, the components are complicated and the cost is high; and the self-locking brackets The cleat and the arch wire are still in surface contact, and the friction force is not small when the force is added; more importantly, the precise control of the position of the teeth is not enough for the self-ligating bracket

Embodiment 1

[0031] like figure 1 and figure 2 As shown, the bracket for correcting dentognathic deformities on the labial side of the present invention includes a base plate 1 , a bracket body 11 , a working wing 31 and a working wing 32 . The bracket body 11 has an archwire slot 2 , and the working wing 31 and the working wing 32 are respectively located on both sides of the archwire slot 2 . The working wing 31 is provided with a ligating wire positioning groove 41 , and the working wing 32 is provided with a ligating wire positioning groove 42 . The groove bottom centerline oo' of the ligating wire positioning groove 41 and the groove bottom centerline cc' of the ligating wire positioning groove 41 are located on the same straight line. And the same straight line where the centerline oo' and the centerline cc' are located is perpendicular to the archwire slot 2 . Of course, in actual use, the same straight line where the centerline oo' and the centerline cc' are located can also be...

Embodiment 2

[0037] like Figure 9 and Figure 10 As shown, the bracket for correcting lingual deformities of the present invention includes a base plate 1 , a bracket body 11 , a working wing 31 and a working wing 32 . The bracket body 11 has an archwire slot 2 , and the working wing 31 and the working wing 32 are respectively located on both sides of the archwire slot 2 . like Figure 11 As shown, the working wing 31 is provided with a ligating wire positioning groove 41 , and the working wing 32 is provided with a ligating wire positioning groove 42 . The groove bottom centerline of the ligating wire positioning groove 41 and the groove bottom centerline of the ligating wire positioning groove 41 are located on the same straight line. And the center line of the groove bottom of the two ligature wire positioning grooves located on the same straight line is perpendicular to the archwire groove 2 . like Figure 9 As shown, the bracket body 11 is further provided with a ligation hole 5...

Abstract

The invention provides a bracket for correcting dentognathic deformity. The bracket comprises a base plate, a bracket body and two work wings, wherein ligature wire positioning channels are formed below the work wings; an arch wire groove is formed in the bracket body, and the two work wings are located on two sides of the arch wire groove respectively; one ligature wire positioning groove is formed in each work wing on each of two sides of the arch wire groove, and the center lines of the bottoms of the ligature wire positioning grooves in the work wings are located in the same line; and a ligation hole which is perpendicular to the arch wire groove and penetrates through the bracket body is formed in the bracket body, and the perpendicular distance between the bottom surface of the arch wire groove and the upper surface of the base plate is larger than the height of the ligation hole. The bracket has the advantages that the friction force between an arch wire and the bracket can be effectively reduced, the structure is simple, and the operation is convenient; and at the same time, by means of the bracket body and accessories, the friction force between the arch wire and the bracket as well as between the arch wire and a ligature wire can be adjusted through selection of ligation of different parts, so that different correction effects are realized.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a bracket and a lock for correcting dental and jaw deformities. Background technique [0002] Brackets for correcting occlusal deformities are important components in the orthodontic treatment of patients with occlusal deformities. In the traditional ligation method, the friction between the arch wire and the bracket is relatively large, which will affect the movement of the teeth. In order to improve the above situation, self-locking brackets have appeared on the market now. Although the self-locking brackets reduce the friction between the arch wire and the brackets to a certain extent, the components are complicated and the cost is high; and the self-locking brackets There is still surface contact between the cleat and the arch wire, and the friction force is not small when the force is applied; more importantly, the precise control of the position of the teeth by the ...
