Examples

As shown in fig. 1 to 7, the present embodiment discloses an abutting orthodontic active self-ligating bracket. Specifically, as shown in fig. 1, the active self-ligating bracket has the following specific structure: the active self-ligating bracket comprises a bracket body 100, a bottom plate 200 and a locking plate 300, wherein the locking plate 300 is an elastic C-shaped locking plate, as shown in fig. 2 to 4, a sliding groove 110 for the locking plate 300 to slide is arranged between the bracket body 100 and the bottom plate 200, a groove 120 is concavely arranged on the bracket body 100, and a locking plate interface 121 is arranged on the inner wall of one side of the groove 120; as shown in fig. 5, a channel 210 is concavely provided on one side of the base plate 200 close to the sliding groove 110, and a telescopic assembly that is extended and contracted toward the bracket body 100 is disposed in the channel 210.

In the embodiment, by configuring the telescopic assembly, when the locking plate 300 enters the sliding slot 110, the telescopic assembly is forced to generate a restoring force, so as to firmly fix the locking plate 300 in the sliding slot 110. When the side of the locking piece 300 close to the slot 120 is opened, the locking piece 300 in the sliding groove 110 cannot slide out of the sliding groove 110; thereby preventing the locking piece 300 from being separated from the bracket body 100 and from being inserted into the sliding groove 110 again. In addition, as the locking plate 300 is fixed in a telescopic assembly mode, the locking plate 300 is convenient to assemble and disassemble.

In this embodiment, as shown in fig. 7, the locking plate 300 has a specific structure that the locking plate 300 includes a positioning end 310, an arc-shaped connecting portion 320 and a sliding end 330; the end of the positioning end 310 is configured with two positioning portions 311, and the positioning portions 311 are used for being inserted into the locking piece interface 121; the arc-shaped connecting part 320 is of an arc-shaped structure, and is designed to be of an arc-shaped structure, so that the arc-shaped connecting part can be conveniently attached to the outer side of the bracket body 100 better and tightly; the positioning end 310 has an opening hole 340 on a side thereof adjacent to the arc-shaped connecting portion 320. The opening hole 340 has an upper and lower oval structure, and is used for facilitating the opening and closing of the groove by a doctor during the treatment process.

In this embodiment, the material of the locking plate 300 is nickel-cobalt-chromium-molybdenum alloy.

In this embodiment, as shown in fig. 2 and fig. 7, the specific connection manner of the locking plate 300 and the bracket body 100 is as follows: the positioning end 310 is used for covering the slot 120 and inserting into the locking piece interface 121, and the sliding end 330 is inserted into the sliding groove 110; the arc-shaped connecting portion 320 is provided with a first stopper portion 321 protruding inward, and the other outer wall of the groove 120 is provided with a first escape portion 122 for escaping from the first stopper portion 321. The first limiting portion 321 is a reinforcing rib, and the reinforcing rib enables the locking plate 300 to generate a relatively constant force value to act on the tooth arch wire or the orthodontic wire in the orthodontic orthopedic treatment process, so that the orthodontic orthopedic process is completed.

In this embodiment, as shown in fig. 6, the specific structure of the telescopic assembly is as follows: the telescopic assembly includes a plurality of pressure springs 221 fixedly installed along the channel 210, and a pressure plate 222 connected to the plurality of pressure springs 221.

In this embodiment, as shown in fig. 4, in order to further enhance the fixing effect of the sliding end 330 and the bracket body 100, a second escape portion 130 is recessed on the surface of the bracket body 100 close to the sliding groove 110.

In this embodiment, the size relationship between the sliding slot 110 and the sliding end 330 is that the width of the sliding slot 110 is greater than or equal to the width of the sliding end 330.

In this embodiment, the torque angle and the shaft inclination angle of the lock plate 300 are set according to the position of the tooth position. The angle of the pitch angle and the angle of the shaft inclination angle are different according to the position of each tooth, and the angle is used for providing the correct orthodontic correction angle of the tooth position for the corresponding tooth in the orthodontic correction process.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
