[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] Please see Figures 1 to 3 An invisible orthodontic traction device includes an invisible aligner 1, a traction hook 3, a J-hook 4, a traction strap 5, and an elastic band 6. The outer wall of the invisible aligner 1 has a groove 2 for embedding the traction hook 3. The traction hook 3 is placed in the groove 2, and the outer wall of the traction hook 3 and the inner wall of the groove 2 are tightly fitted together.

[0027] The outer wall of the traction hook 3 is snapped to the inner wall of the traction ring 41. The traction ring 41 is fixedly connected to one end of the J-shaped hook 4, and the other end of the J-shaped hook 4 is fixedly connected to the mounting hook 42.

[0028] The traction strap 5 has a hook hole 51 on one side wall at the end, and a mounting cap 52 is provided in the middle of the traction strap 5.

[0029] The J-type hook 4 is connected to one end of the mounting hook 42, which passes through the hook hole 51 and is slidably connected to the mounting cap 52.

[0030] The traction strap 5 is fixedly connected to the elastic band 6 by screws.

[0031] In this embodiment, as Figure 1 As shown, there are two grooves 2, which are located in the anterior tooth area on both sides of the invisible aligner 1. Each groove 2 contains a traction hook 3. When placing the traction hook 3, the orientation of the traction hook 3 can be adjusted by adjusting the embedding direction of the traction hook 3 into the groove 2.

[0032] However, it is important to emphasize that the number and position of the grooves 2 are not limited. Orthodontics is a systematic approach, and there will be different solutions for each user. Each person's bones require different traction angles and forces. Therefore, the grooves 2 can be set in multiple positions and in multiple numbers. Correspondingly, the traction hooks 3 will also be set in different positions and in different numbers. In addition, the orientation of the traction hooks 3 can also be changed according to the different traction angle requirements, such as upward, downward, left, right, forward, backward, etc. It can be set at an angle.

[0033] Furthermore, regarding the shape of the traction hook 3, in this embodiment, the traction hook 3 is J-shaped, but in reality, it can be any of the 26 letters of the English alphabet (AZ), or it can be rectangular, square, circular, triangular, rhomboid, elliptical, etc. Among them, the J-shaped, S-shaped, H-shaped, E-shaped (suitable for dual traction), and O-shaped are more commonly used.

[0034] The connection between the groove 2 and the traction hook 3 can be varied. For example, it can be bonded with chemical adhesive, integrally molded, or threaded. Specifically, the traction hook 3 can have an externally threaded mounting part, and the groove 2 can have an internal thread, with the two connected by threads. It can also be magnetic, or if other materials are used for invisible orthodontic devices in the future, such as metal, it can be welded, etc.

[0035] In this embodiment, as Figure 1 As shown, the traction hook 3 has an overall hook-shaped structure.

[0036] In this embodiment, as Figure 1 As shown, the traction hook 3 and the groove 2 are integrally formed during production.

[0037] In this embodiment, as Figure 4 As shown, the front traction device 7 includes a V-shaped bracket 71, with pads 72 fitted at both the upper and lower ends of the V-shaped bracket 71. A traction bracket 73 is fixedly fitted at the lower end of the V-shaped bracket 71, located between the two pads 72. The traction bracket 73 is connected to the traction hook 3 by an elastic rubber band 74. In use, the V-shaped bracket is attached to the front of the face by two pads that rest against the forehead and jaw respectively. Then, the elastic rubber bands are hung on both sides of the traction bracket, and the elastic rubber bands on both sides are connected to the traction hooks respectively. By adjusting the number of turns of the elastic rubber bands around the traction bracket, the traction force of the front traction device on the invisible aligner can be controlled, thereby achieving the effect of correcting maxillary deformity and preventing the lower jaw from being too long.

[0038] The invisible orthodontic traction device works as follows:

[0039] First, the invisible aligner 1 is worn on the teeth that need to be corrected. Then, the elastic band 6 is worn on the top of the patient's head as a fixation base. The two traction straps 5 are placed on the patient's cheeks on both sides to ensure symmetry. The end of the J-hook 4 with the mounting hook 42 is passed through the hook hole 51 at the end of the traction strap 5 and suspended on the mounting cap 52 in the middle of the traction strap 5 through the mounting hook 42. Then, the traction ring 41 at the other end of the J-hook 4 is suspended on the traction hook 3 on the corresponding side of the invisible aligner 1. The same operation is repeated on the other side to complete the wearing of the device. This orthodontic system transmits the force to the teeth through the invisible aligner 1 for correction by the traction force formed by the traction strap 5 and the J-hook 4. At the same time, it can produce an auxiliary corrective effect on the bones around the teeth. The traction hook 3 is set in the groove 2 on both sides of the anterior tooth area of ​​the invisible aligner 1 and is integrally molded with the aligner. The integral structure makes the device look neat and smooth, significantly improving the wearing comfort and realizing the synergistic effect of tooth correction and jaw adjustment.

[0040] Before the traction hook 3 and the invisible aligner 1 are integrally formed, the insertion direction of the traction hook 3 into the groove 2 can be adjusted to achieve the effect of adjusting the hook orientation of the traction hook 3, thereby adapting to the use of the front traction device 7. When using the front traction device 7, the pads 72 at the upper and lower ends of the V-shaped bracket 71 are placed against the forehead and jaw respectively to attach the front traction device 7 to the front face. Then, two elastic rubber bands 74 are hung on both sides of the traction bracket 73. The elastic rubber bands 74 on both sides are connected to the traction hook 3. By adjusting the number of turns of the elastic rubber bands 74 on the traction bracket 73, the traction force of the front traction device 7 on the invisible aligner 1 can be controlled, thereby achieving the effect of correcting the upper jaw deformity.
