[0025] During specific implementation: the first bracket 2 is used for the first and second tooth positions, that is, the front teeth and the teeth next to the front teeth. When in use, the base 1 is fixed on the teeth, the first locking block 202 is opened, and the first main arch wire is placed in the first arch wire slot 204 or only close to but not completely included in the first arch wire slot 204. The dental arch shape is maintained or adjusted as needed. At the same time, by adding an additional nickel-titanium arch wire in the round hole, the teeth can be aligned faster in the early stage of treatment, so that the first arch wire slots of all tooth brackets can be included in the main arch wire as soon as possible, achieving the purpose of synchronous and rapid movement; the length of the first arch wire slot 204 is shorter than the width of the first mounting block 201 The length of the archwire in the first archwire slot 204 is shorter, which increases the freedom of the first bracket 2 and allows the use of an archwire with greater rigidity earlier to control the dental arch shape while allowing the teeth to tilt and move freely, and the tilting and movement are within a certain controllable range; after a period of time when the teeth are quickly aligned and the gap is basically closed, the second locking block 302 is opened, the first main archwire is removed, and replaced with a second thicker nickel-titanium strip main archwire. The strip main archwire helps the teeth move in a predetermined direction and path by applying continuous and gentle force, thereby achieving the purpose of more precise control of tooth movement.

[0026] Example 2: Reference Figure 1 and Figure 3 A second bracket 3 is provided at the top of the base 1. The second bracket 3 includes a second mounting block 301. The top of the base 1 is fixedly connected to the bottom of the second mounting block 301. The second mounting block 301 facilitates positioning of the arch wire.

[0027] As a further implementation scheme of the above technical solution: a second archwire slot 304 is opened inside the second mounting block 301. The second archwire slot 304 is a square hole. A second locking block 302 is provided at the top of the second mounting block 301. The second archwire slot 304 is convenient for accommodating an archwire.

[0028] As a further implementation scheme of the above technical solution: a second ball handle 303 is fixedly provided on one side of the second mounting block 301, and a second circular hole 305 is opened inside the second mounting block 301. The second circular hole 305 is located on the side of the second archwire slot 304, and the second circular hole 305 is convenient for accommodating additional archwires.

[0029] During specific implementation: the second bracket 3 is used for the third tooth position. When in use, the base 1 is fixed on the tooth, the second locking block 302 is opened, and the first main arch wire is placed in the second arch wire slot 304. Since the length of the first arch wire slot 304 is shorter than the width of the first mounting block 201, the length of the arch wire in the first arch wire slot 304 is shorter, which increases the freedom of the first bracket 2. Combined with the smaller traction force, the tooth can quickly and freely move distally, providing space for the rapid alignment and retraction of the anterior teeth. At the same time, by adding an extra archwire in the circular hole, the teeth with severe misalignment in the early stage of treatment can be aligned as soon as possible, so that the first archwire slot of the bracket can be incorporated into the main archwire as soon as possible; after the teeth are basically aligned and the gap is basically closed, the second locking block 302 is opened, the main archwire is removed, and replaced with a thicker nickel-titanium ribbon main archwire. The length of the second archwire slot 304 is shorter than the width of the second mounting block 301, so that the length of the archwire in the second archwire slot 304 is shorter, so that the freedom of the second bracket 3 is improved. The slot length of the second archwire slot 304 is shorter than the slot width, so that the second archwire slot 304 is more suitable for the ribbon archwire, which is convenient for better matching the wide and flat shape of the ribbon archwire and providing better stability and torque control; the first mounting block 201 and the second mounting block 301 have the same width, and the length of the second archwire slot 304 is less than the width of the second mounting block 301 and longer than the length of the first archwire slot 204, so that the archwire can provide a greater torque to the third tooth position, and the stability of the second bracket 3 can be improved while ensuring that the second bracket 3 has a high degree of freedom. Through the above design, the goal of synchronous and rapid movement of teeth can be achieved, shortening the treatment period while improving the control of the accuracy of tooth position.

At the same time, by adding an additional nickel-titanium arch wire in the round hole, the teeth can be aligned faster in the early stage of treatment, so that the first arch wire slots of all tooth brackets can be included in the main arch wire as soon as possible, and the purpose of synchronous and rapid movement can be achieved; the length of the first arch wire slot 204 is shorter than the width of the first mounting block 201, so that the length of the arch wire in the first arch wire slot 204 is shorter, so that the freedom of the first bracket 2 is improved, and the arch wire with greater rigidity can be used earlier to control the dental arch shape while allowing the teeth to tilt and move freely, and the tilt The oblique movement is within a certain controllable range; after a period of time when the teeth are quickly aligned and the gap is basically closed, the second locking block 302 is opened, the first main arch wire is removed, and replaced with a second thicker nickel-titanium strip main arch wire. The strip main arch wire helps the teeth move in a predetermined direction and path by applying continuous and gentle force, thereby achieving the purpose of more precise control of tooth movement; the first mounting block 201, the second mounting block 301 and the third mounting block 401 have the same width, and the length of the third arch wire slot 403 is less than the width of the third mounting block 401, and longer than the length of the first arch wire slot 204 and the second arch wire slot 304, so that the arch wire can provide a greater torque to the fourth and fifth tooth positions, and the stability of the third bracket 4 can be improved while ensuring that the third bracket 4 has a certain degree of freedom.
