This treatment is usually carried out by dentists or orthodontic specialists and is mainly applied to crowded teeth, irregular dental arches, open bite or deep overbite, and aesthetic problems. Most orthodontic methods use metal or ceramic brackets and metal wires to move teeth by gradually adjusting the tension in the brackets.

[0003] In the patent with the publication number CN 216908159 U, a dental orthodontic bracket is disclosed. The utility model can ensure the flexible and close contact between the dental orthodontic bracket and the tooth surface, making the positioning of the dental orthodontic bracket accurate and adjustable; at the same time, the traction wire is restricted inside the installation groove of the correction base through the closed cover, effectively protecting the traction wire and extending the service life of the traction wire.

[0004] Although the above technology uses a flexible material to adhere to the tooth surface, due to the unevenness and concavity-convexity of the tooth surface, its complexity will cause the adhesion area of the orthodontic bracket to be uneven or incomplete, resulting in voids on the adhesion surface, thus affecting the firmness of the bracket. If the bracket is not well adhered to the tooth surface, it may cause the bracket to fall off or shift, affecting the effect and progress of the entire orthodontic process. Therefore, it has certain limitations, so innovation is made on this technology. Summary of the Utility Model

Detailed implementation mode

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the protection scope of the present utility model.

[0021] In orthodontics, an orthodontic bracket needs to be used. An orthodontic bracket provided by the present utility model is specifically used for orthodontic operations. Compared with an orthodontic bracket with the publication number of CN 216908159 U, by adding spring bumps inside the airbag, this device can fill the tiny irregularities on the tooth surface during adhesion, thereby adhering more firmly to the tooth surface and reducing the risk of detachment. Embodiment

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0023] It includes a fixing member 1. An airbag 2 is installed on the front of the fixing member 1. A plurality of spring bumps 4 are fixedly installed on the back of the inner wall of the airbag 2. An air injection port 3 is fixedly penetrated through a corner at the top of the airbag 2. A correction base 5 is fixedly installed on the back of the fixing member 1. An anti-slip pad 7 is fixedly installed at the bottom end of the inner wall of the correction base 5. A steel bar through hole 6 is opened in the middle of the correction base 5. A pressing pad 9 is provided at the top end inside the steel bar through hole 6. An adhesive is coated on the surface of the airbag 2. The airbag 2 is arranged to be expandable and contractible, and can expand and contract during adhesion. Therefore, it can better adapt to the irregularities and concavities on the tooth surface, enabling the filling of voids and providing a more uniform pressure distribution during the adhesion process, thereby enhancing the covering and fitting effect of the adhesive. The sizes between the plurality of spring bumps 4 are all the same, and the gaps between the plurality of spring bumps 4 are all the same.

[0024] In this embodiment, a fastening bolt 8 is threadedly connected to the middle of the top end of the correction base 5. The fastening bolt 8 penetrates through the steel bar through hole 6, and the middle of the bottom end of the fastening bolt 8 is rotationally connected to the middle of the top end of the pressing pad 9 through a provided rotating shaft. The cooperation between the fastening bolt 8 and the pressing pad 9 serves to limit and fix the steel bar inside the steel bar through hole 6, thereby ensuring the stability of the steel bar installation. When necessary, the pressing pad 9 can also be loosened to adjust the steel bar.

[0025] In this embodiment, a knob 10 is fixedly installed at the top end of the fastening bolt 8, and a groove 13 is formed at the top end of the knob 10. An auxiliary wrench 14 is movably inserted into the inner wall of the groove 13. Since the device operates on the tooth surface, the provided auxiliary wrench 14 plays an auxiliary role, enabling better operation within the patient's oral cavity and driving the knob 10 to rotate.

[0026] In this embodiment, a fixing ring 11 is fixedly installed on the outer wall of the knob 10. A clamping block 12 is rotatably installed on the outer wall of the fixing ring 11 through a connecting shaft. A clamping groove 15 is formed in the middle of the top end of the back surface of the correction base 5. The clamping block 12 is movably clamped with the clamping groove 15. After the steel bar is fastened, the clamping block 12 stays at the position of the clamping groove 15. At this time, rotating the clamping block 12 can be limited within the clamping groove 15, thus playing a role in limiting the knob 10.

[0027] In this embodiment, auxiliary clamping grooves 16 are formed on both sides of the top end of the correction base 5. The inner walls of the two auxiliary clamping grooves 16 are provided with serrations. The symmetrical design of the two auxiliary clamping grooves 16 helps medical staff to operate with tweezers. The serrations formed on their surfaces increase the friction with the tweezers, making the operation more convenient.

[0028] Working principle: When in use, first place the fixing member 1 on the tooth surface. Inject air into the airbag 2 through the air injection port 3. After the airbag 2 expands, apply a sufficient amount of adhesive on the airbag 2. After the adhesive is attached to the tooth, discharge the air inside the airbag 2 through the air injection port 3. Then, under the action of its own spring, the spring bump 4 presses the airbag 2, so that the adhesive fills the uneven surface of the tooth, thereby increasing the contact area between the adhesive and the tooth surface. Further, after passing the steel bar through the correction base 5, insert the auxiliary wrench 14 into the groove 13 and rotate it. While driving the fastening bolt 8 to rotate, further drive the pressing pad 9 to press the steel bar on the surface of the anti-slip pad 7 under the cooperation of the rotating shaft, so as to limit and fix the steel bar. At this time, loosen the auxiliary wrench 14 and rotate the clamping block 12 to clamp it into the clamping groove 15 for limiting, thereby realizing the limitation of the fastening bolt 8 and thus realizing the installation of the device.
