Problems solved by technology

[0005] 1. Since the width of the cover slides in the chute of the bracket main body, the width of the cover must be smaller than the width of the bracket main body, resulting in a shorter contact length between the cover and the archwire when the bracket is closed, which in turn affects It improves the control of tooth torque in clinical orthodontic treatment;
[0006] 2. The mechanical structure of the prior art makes the outer surface close to the inner wall of the oral cavity not smooth enough, which is easy to cause scratches to the inner wall of the oral cavity;
[0007] 3. The structure is complicated to install, the assembly speed is slow, and the production efficiency is low

Embodiment 1

[0084] Such as Figure 1 to Figure 6 As shown, the embodiment of the present application provides a self-locking appliance, which is characterized in that it includes:

[0085] Bracket bottom 1;

[0086] Bracket main body 2, which is arranged on the top of the bracket mesh bottom 1;

[0087] An arch wire slot 3, which is arranged on the top of the bracket main body 2;

[0088] a cover sheet 4, which is slidably installed on the top of the bracket main body 2;

[0089] A limit mechanism 5, which is used to fix the position of the slid cover sheet 4;

[0090] Wherein, the sliding direction of the cover piece 4 is perpendicular to the extending direction of the archwire groove 3 .

[0091] In the embodiment of the present application, the above-mentioned self-locking appliance is adopted, and the cover piece 4 adopts a full-covering structure, so that the outer surface of the product is round and smooth, and the irritation to the inner wall of the oral cavity is less. The bo...

Embodiment 2

[0093] In this embodiment, in addition to including the structural features of the preceding embodiments, it also includes:

[0094] A chute 9, which is arranged on the top of the bracket main body 2 and extends perpendicularly to the archwire slot 3;

[0095] Slider one 10 is fixedly installed on the bottom of the side wall of the cover sheet 4 and is slidably installed in the slide groove one 9 .

[0096] In this embodiment, due to the adoption of the above-mentioned structure, through the setting of the sliding groove one 9 and the sliding block one 10, the cover plate will not be detached from the top of the bracket main body 2 when it slides in a direction perpendicular to the archwire groove 3 .

Embodiment 3

[0098] In this embodiment, in addition to the structural features of the foregoing embodiments, the limiting mechanism 5 includes:

[0099] first hole 501;

[0100] The second hole 502 has a diameter greater than that of the first hole 501;

[0101] A connecting groove 503, the two ends of which communicate with the first hole 501 and the second hole 502 respectively;

[0102] A through slot 504, which is arranged on the top of the bracket main body 2;

[0103] Elastic stopper 6, one end of which is inserted into the first through groove 504, and the other end extends into the connecting groove 503 to slide and fit with it so as to engage with the second hole 502;

[0104] Wherein, the diameter of the first hole 501 is equal to the width of the connecting groove 503, the first hole 501, the second hole 502 and the connecting groove 503 are all arranged at the bottom of the cover sheet 4 and the connecting groove 503 is perpendicular to the archwire groove 3 set up.

Abstract

The invention discloses a self-locking appliance, which comprises a bracket net bottom, a bracket main body arranged at the top of the bracket net bottom, an arch wire groove arranged at the top of the bracket main body, a cover plate slidably mounted at the top of the bracket main body, and a limiting mechanism used for fixing the position of the cover plate after sliding, wherein the sliding direction of the cover plate is perpendicular to the extending direction of the arch wire groove, the cover plate is of a full-covering structure, so that the outer surface of the product is round and smooth, stimulation to mucosa on the inner wall of an oral cavity is small, and the cover plate is convenient in installation, has a high assembling speed and high production efficiency through arrangement of the limiting mechanism.

Description

technical field [0001] The invention relates to a self-locking appliance. Background technique [0002] In the first century A.D., the Roman physician Celsus taught people to use fingers to push teeth to correct misaligned teeth, which can be regarded as the most primitive orthodontic technique. The development of modern orthodontics began at the end of the 19th century and the beginning of the 20th century. American scholar Angle developed orthodontics as a branch of stomatology. In 1928, he published the square wire appliance, established the orthodontic system of the fixed appliance, and laid the foundation for the development of modern orthodontics and orthodontic technology. With the development of the times, the advancement of technology and the improvement of manufacturing technology, more and more self-locking brackets with complex structures have been used clinically. [0003] At present, self-ligating brackets are widely used in domestic orthodontics as a half-c...
