[0027] In the description of the embodiments of the present application, it should also be noted that unless otherwise explicitly specified and limited, if the terms "provided", "installed", "connected", "connected" appear, they should be understood in a broad sense, for example, they can be fixedly connected, or can be detachably connected, or integrally connected; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium; can be the communication between two elements inside. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Embodiment 1:

[0029] According to the utility model example, a tooth orthodontic correction bracket, the first bracket part 10 side is provided with two threaded holes, the threaded hole is cooperated with the micro screw bolt 30, the micro screw bolt 30 can push the first push plate 12 when rotating, the push plate is trapezoidal, and can be telescopic in the through slot.

[0030] As Figs. 1 to 4 The trapezoidal lug 11 of the first bracket part 10 and the trapezoidal slot 21 of the second bracket part 20 are matched with each other, so that the first bracket part and the second bracket part can only produce relative sliding in one direction, and then the relative position of the first bracket part and the second bracket part is fixed by the bolt between the first lock hole 14 and the second lock hole, so that the transverse distance of the first bracket part and the second bracket part can be fixed and adjusted.

[0031] According to the utility model example, a tooth orthodontic correction bracket, the first bracket part 10 side is provided with two threaded holes, the threaded hole is cooperated with the micro screw bolt 30, the micro screw bolt 30 can push the first push plate 12 when rotating, the push plate is trapezoidal, and can be telescopic in the through slot.

[0032] According to the utility model example, a tooth orthodontic correction bracket, the second bracket part 20 side bottom is provided with a threaded hole, the threaded hole is cooperated with the micro screw bolt 30, the micro screw bolt 30 can push the second push plate 22 when rotating, the push plate is trapezoidal, and can be telescopic in the second bracket part 20 bottom.

[0033] As Fig. 4As shown, when the archwire 50 loosens during orthodontic treatment, the archwire 50 can be deformed by pushing the first pusher plate 12, thereby lengthening the archwire 50 within the bracket while maintaining the overall length of the archwire 50, effectively tightening it. Since each bracket is adjustable, the overall tightening effect is considerable and highly precise, allowing for adjustment only between two teeth. In practical use, first increase the relative distance between the first bracket portion 10 and the second bracket portion 20, then push and rotate the micro-bolt 30, pushing the first pusher plate 12 and the second pusher plate 22 until sufficient force is applied to the archwire 50, at which point the adjustment stops.

[0034] According to an example of the present invention, a countersunk hole 40 is provided in front of the threaded hole of the first bracket portion 10 and the second bracket portion 20.

[0035] like Fig. 4 As shown, the countersunk hole 40 allows the micro bolt 30 to be entirely inside the correction bracket, preventing any part from being exposed outside the bracket and causing discomfort when worn.

[0036] According to an example of the present invention, an orthodontic bracket is provided with rounded corners for the archwire groove 13, the first push plate 12, and the second push plate 22.

[0037] Rounding the corners where the bowwire passes through prevents the bowwire from breaking due to excessive force applied when the push plate presses against it. It also protects the bowwire from slippage during normal use.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
