Embodiment 1

[0031] see figure 1 , refer to Figure 2-4 , the passive self-ligating bracket for orthodontics of the present invention comprises an orthodontic bracket body 1, a dental arch wire 2, a sliding cover 3, a shrapnel 4, a pin 5, and a net bottom 6;

[0032] The orthodontic bracket body 1 is provided with a groove 9 capable of accommodating the orthodontic arch wire 2, and the two sides of the groove 9 are provided with a first ligation wing 1a and a second ligation wing 1b, wherein the first ligation wing 1a is provided with There is a guide groove 11 where the slide cover 3 slides. The bottom of the guide groove 11 is provided with a hole 10 through which the pin 5 passes and a guide rib groove 12 for sliding positioning and guiding of the slide cover 3. The bottom of the slide cover 3 is provided with a blind hole 13. The slide cover 3 The bottom is provided with positioning guide ribs 14, and the shrapnel 4 is embedded in the blind hole 13 of the sliding cover 3;

Embodiment 2

[0040] see Figure 11 , refer to Figure 12 , the figure shows another embodiment of another passive self-ligating bracket for orthodontics related to the present invention, the passive self-ligating bracket for orthodontics includes an orthodontic bracket body 1, a dental arch wire 2 , sliding cover 3, shrapnel 4, pin 5, net bottom 6;

[0041] Such as Figure 12 As shown, when the slide cover is opened or closed, the interaction between the shrapnel 4 and the pin 5 is as follows, by pushing the front end face 8 of the slide cover 3 with a tool or the fingertips, and pushing in the direction of the arrow, when the slide cover 3 is started and closed, the pin will 5 is gradually in contact with the shrapnel 4. When the sliding cover 3 moves from the position of the pin 5 to the position 5a, the pin 5 and the middle sides 4a and 4b of the shrapnel 4 begin to contact and receive force, and the sliding cover 3 continues to move and close. When the pin 5 When separated from the ...

Abstract

The invention discloses a passive self-ligating bracket for orthodontics. The passive self-ligating bracket comprises an orthodontic bracket body, a slide cover, a dowel, an elastic piece and a net bottom. According to the passive self-ligating bracket for orthodontics, the slide cover is stable during normal work of the bracket, an orthodontic archwire can be well fixed in a groove, slide correction is realized, and correction period is shortened.

Description

technical field [0001] The invention relates to the technical field of orthodontic treatment, in particular to a passive self-locking bracket for orthodontics. Background technique [0002] In recent years, with the popularization and promotion of orthodontics, more and more people have received orthodontic treatment, which has also promoted the rapid development of the orthodontic manufacturing industry. Alignment, especially for orthodontic brackets. Orthodontic brackets include ordinary brackets and self-ligating brackets. Since ordinary brackets are mainly ligated with stainless steel wires or rubber rings, these two kinds of ligations are directly applied to the dental arch wires, which have a large impact on the arch wires and brackets. Friction and arch wire cannot slide freely in the bracket, which greatly prolongs the treatment period, so now major manufacturers are vigorously developing self-ligating brackets, which have the advantages of simple operation and shor...
