[0031] The following is combined with Figure 1 to Figure 5 The utility model is further described in detail, but it is not intended to limit the utility model.

[0032] like Figure 1 and 2 As shown, in one embodiment of the utility model, the orthodontic bracket comprises a base 2, a groove 3, a first locking piece 4, a second locking assembly 5 and at least two bracket wings 1; all the bracket wings 1 are arranged side by side on the base 2, and an assembly gap 101 is provided between two adjacent bracket wings 1; the groove 3 is arranged to pass through the upper ends of all the bracket wings 1, and is used to install an arch wire; the first locking piece 4 is connected to the bracket wing 1, and can extend to the groove 3; and a limiting cavity 12 is provided in the first locking piece 4, and the limiting cavity 12 is communicated with the groove 3; the second locking assembly 5 is connected to the assembly gap 101, and is used to be clamped with the arch wire.

[0033] The technical solution of the utility model can further improve the assembly stability with the arch wire by adopting the dual assembly effects of the limiting cavity of the first locking member to limit the assembly of the arch wire and the clamping limiting effect of the second locking component, reduce the installation shaking and falling off of the arch wire, thereby improving the stability of the structure, ensuring the safety of use, and avoiding damage to the human body caused by the displacement of the arch wire.

[0034] Among them, Figure 1 and 2 As shown, the shape of the bracket wing 1 is a U-shaped structure; the number of the first locking members 4 corresponds to the number of the bracket wings 1; and the first locking member 4 is arranged in the middle of the bracket wing 1, and the limiting cavity 12 is formed between the first locking member 4 and the bracket wing 1. This structure can achieve the limiting effect on multiple parts of the archwire through multiple first locking members 4, thereby improving the stability of the structure.

[0035] Specifically, in some embodiments, Figure 2 As shown, the first locking member 4 is a first locking block, and a concave surface is provided at the bottom of the first locking block, and the limiting cavity 12 is formed between the concave surface and the bracket wing 1. The first locking block is a square locking block. The concave surface can adapt to the limiting effect of archwires of more different sizes, thereby increasing the scope of application.

[0036] Specifically, in some embodiments, Figure 2 As shown, at least one first elastic member 41 is provided at the bottom of the first locking member 4; one end of the first elastic member 41 is connected to the bracket wing 1; and the limiting cavity 12 is formed between the first locking member 4, the first elastic member 41 and the bracket wing 1. This structure can improve the elastic limiting stability of the arch wire through the limiting effect of the elastic stress of the first elastic member, reduce damage to the arch wire, and thus improve the stability of assembly and use.

[0037] Specifically, in some embodiments, Figure 2 and 3 As shown, when the first locking member 4 is not assembled with the arch wire, the volume of the limiting cavity 12 formed between the first elastic member 41 and the bracket wing 1 is S1; when the first locking member 4 is assembled with the arch wire, the volume of the limiting cavity 12 formed between the first elastic member 41 and the bracket wing 1 is S2; and S2 ≥ S1. That is, when the arch wire is installed, the supporting effect of the arch wire increases the volume of the limiting cavity 12 and makes it close to the arch wire, thereby improving the elastic limiting stability of the arch wire, reducing damage to the arch wire, and improving the stability of assembly and use.

[0038] Specifically, in some embodiments, Figure 1 and4 As shown, the second locking assembly 5 includes a first locking cover plate 51 and a second locking cover plate 52; the first locking cover plate 51 is movably connected to the side end surface of the bracket wing 1; the first locking cover plate 51 is provided with a first limiting hole 511, and the first limiting hole 511 is communicated with the groove 3; the second locking cover plate 52 is movably connected to the side end surface of the bracket wing 1; the second locking cover plate 52 is provided with a second limiting hole 521; the second limiting hole 521 is communicated with the groove 3. This structure can achieve the limiting stability of the arch wire through the dual limiting effect of the first limiting hole 511 and the second limiting hole 521, avoid the sliding and dislocation of the arch wire, and thus improve the stability of assembly and use.

[0039] Wherein, in some embodiments, Figure 4 As shown, a first positioning column 513 is provided at the side end of the first locking cover plate 51, and the first positioning column 513 is rotatably connected to the side end surface of the bracket wing 1; a second positioning column 523 is provided at the side end of the second locking cover plate 52; the second positioning column 523 is rotatably connected to the side end surface of the bracket wing 1.

[0040] Wherein, in some embodiments, Figure 4 As shown, a second elastic member 512 is provided at the bottom of the first locking cover plate 51; one end of the second elastic member 512 is connected to the base 2; a third elastic member 522 is provided at the bottom of the second locking cover plate 52; one end of the third elastic member 522 is connected to the base 2. Figure 4 and 5 As shown, when the arch wire is assembled with the first locking cover plate 51 and the second locking cover plate 52 respectively, the first limiting hole 511 and the second limiting hole 521 are arranged to overlap; when the arch wire is not assembled with the first locking cover plate 51 and the second locking cover plate 52 respectively, the projection of the first limiting hole 511 toward the diameter direction of the groove 3 and the projection of the second limiting hole 521 toward the diameter direction of the groove 3 at most partially overlap. That is to say, when the arch wire is not assembled with the first locking cover plate 51 and the second locking cover plate 52 respectively; the first locking cover plate 51 and the second locking cover plate 52 are tilted up under the action of the elastic member, thereby causing the first limiting hole 511 and the second limiting hole 521 to be misaligned; when the arch wire is assembled with the first locking cover plate 51 and the second locking cover plate 52 respectively; the first locking cover plate 51 and the second locking cover plate 52 are both contracted downward to achieve the overlap of the first limiting hole 511 and the second limiting hole 521, thereby ensuring the stability of the arch wire clamping.

[0041] Specifically, in some embodiments, Figure 1 and 2As shown, the bottom of the base 2 is provided with a curved surface 21. Through the fitting effect of the curved surface 21, it is avoided that the inner side of the patient's lips is damaged by placement, and it can better fit the surface of the patient's teeth.

[0042] The utility model also proposes a dental brace, which includes an archwire and an orthodontic bracket, wherein a portion of the archwire is received inside the orthodontic bracket; the specific structure of the orthodontic bracket refers to the above embodiment, and since the dental brace adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The material of the archwire is any one of stainless steel, nickel-titanium alloy, β-titanium alloy and cobalt-chromium alloy.

[0043] Among them, orthodontic appliances (dental braces) are appliances used for professional supervision, guidance and correction of a patient's misaligned teeth. The many benefits of orthodontic treatment include obtaining and maintaining correct bite function, improved facial aesthetics, and easier maintenance of dental hygiene. Orthodontic appliances are arranged to mechanically engage with the patient's teeth and apply gentle mechanical forces that gradually move the teeth toward the correct position to achieve a correct bite (or closure).

[0044] The orthodontic bracket may be made of metal, ceramic, plastic, etc.
