Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1-3, the present invention discloses an active bracket, comprising: a base plate 10, a bracket base 20, upper bracket wings 30, and a resilient tab 40. Wherein, one side of the bottom plate 10 is used for being bonded on the tooth surface, and the other side is fixed with a bracket seat 20; a groove 21 for accommodating the arch wire is arranged in the slot support seat 20. The upper bracket wing 30 is connected to the bracket base 20; one end of the elastic sheet 40 is connected to the end of the upper bracket wing 30, and the other end of the elastic sheet 40 is placed in the groove 21. More specifically, the elastic piece 40 is disposed at one end of the slot 21 near one side wall of the slot 21 to make room for accommodating the archwire.

When the bracket is used, the arch wire is pressed into the groove 21, the elastic sheet 40 is extruded and deformed, the acting force is released to tightly abut against the arch wire, and the arch wire is ensured to be always in close contact with the groove 21, so that the correcting force acts on the bracket accurately, the control force on the teeth is enhanced, and the teeth move more accurately. Meanwhile, the elastic sheet 40 is jointed with the upper bracket wings 30, so that the whole connection of the bracket is smoother and simpler, compared with the way that the elastic sheet 40 is directly arranged on the inner wall of the groove 21, the utility model has fewer sections and reduces the risk that the bracket may damage the oral cavity of a patient. In addition, the elastic sheet 40 can adjust the angle according to the correction requirements of each stage, and the bracket and the arch wire can be ensured to be always in an active state due to the inconsistent sizes of the arch wire in each stage, so that the teeth can be more accurately moved.

When the elastic piece 40 needs to exert the maximum acting force on the arch wire, the extending direction of one end of the elastic piece 40 positioned in the groove 21 is preferably parallel to the inner side wall of the groove 21, the component force loss is minimum, and the acting force exerted on the arch wire by the elastic piece 40 is maximum after the elastic piece 40 is reset.

Since the appliance is usually made of metal material, which is easy to scratch the soft oral cavity, in order to reduce this risk, it is preferable that the connecting position of the elastic sheet 40 and the upper bracket wing 30 is a smoothly transiting arc-shaped bent structure, so that the edge of the bracket tends to be smooth, and the oral cavity is not scratched.

Preferably, the active bracket further comprises a lower bracket wing 50. The lower bracket wing 50 is connected to an outer side of the bracket base 20, and the upper bracket wing 30 and the lower bracket wing 50 are respectively located at two opposite outer sides of the bracket base 20. The upper bracket wings 30 and the lower bracket wings 50 cooperate together to provide a secure position for the ligature.

Preferably, a concave hole 31 is formed at the connecting position of the upper bracket wing 30 and the bracket seat 20 for the ligature wire to pass through. By designing the concave hole 31, the upper bracket wing 30 does not need to be additionally provided with the wing-shaped structure 51.

Preferably, the lower bracket wings 50 have two wing-like structures 51 extending outwardly relative to the other end to which the bracket base 20 is attached for providing a location for ligature attachment.

The elastic sheet 40 is preferably made of nitinol, but is not limited thereto, and other known elastic materials are within the scope of the present invention.

Preferably, the base plate 10, the bracket holder 20, the upper bracket wing 30, and the lower bracket wing 50 may be made of a metal material such as nickel-chromium, cobalt-chromium, or stainless steel.

The utility model can have two manufacturing forms: (1) the bracket is integrally manufactured by adopting a 3D printing mode, namely, the bottom plate 10, the bracket seat 20, the upper bracket wings 30, the lower bracket wings 50 and the elastic sheet 40 are integrally formed, and the printing material can be nickel-titanium alloy material; (2) the elastic sheet 40 is welded, the base plate 10, the bracket holder 20, the upper bracket wings 30 and the lower bracket wings 50 can be integrally printed and molded, and the elastic sheet 40 is welded and fixed at the positions of the upper bracket wings 30.
