[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: a combined orthodontic appliance, including an archwire 1, with a plurality of metal brackets 2 on the archwire 1. An adjustable connector consisting of a convex ring 3 and a rotating block 4 is provided on the back side of each metal bracket 2. The convex ring 3 is welded and fixed to the outside of the metal bracket 2. The rotating block 4 is movably disposed inside the convex ring 3, and elastic clips 5 symmetrically distributed vertically are welded and fixed to the outside of the rotating block 4. The gaps between the elastic clips 5 form a locking slot for engaging with the appropriate position on the archwire 1. A fine-tuning mechanism consisting of a micro rack 7 and a micro gear 8 is provided between the upper ends of the convex ring 3 and the rotating block 4. The micro rack 7 has an arc-shaped structure and is bonded and fitted to the inner wall of the upper end of the convex ring 3 through an arc-shaped notch. The micro gear 8 is connected through a rectangular notch... The opening is located inside the upper end of the rotating block 4. When the position of the metal bracket 2 needs adjustment, the doctor can rotate the rotating block 4 inside the convex ring 3, causing the micro-gear 8 and micro-rack 7 inside the rotating block 4 to interact, thus achieving fine-tuning. Furthermore, the elastic locking piece 5 on the outer side of the rotating block 4 can find a suitable position on the archwire 1 and securely engage according to the adjustment requirements, ensuring that each metal bracket 2 can be adjusted independently of other brackets without affecting the stability of the overall structure. This not only improves the independent adjustment capability of each metal bracket 2 but also makes the orthodontic process more flexible and precise, solving the problem in existing technologies where adjusting a single bracket affects the entire orthodontic appliance, avoiding the complication of the correction process and the potential prolongation of the correction period. Furthermore, this design allows doctors to flexibly adjust treatment plans according to individual patient differences, improving both the orthodontic effect and patient comfort, simplifying installation and maintenance, and increasing treatment efficiency. Both sides of the convex ring 3 are welded with arc-shaped sliders 6, and the inner edges of both sides of the rotating block 4 are provided with arc-shaped grooves that cooperate with the structure of the arc-shaped sliders 6. When adjusting the position of the metal bracket 2, the convex ring 3 can drive the arc-shaped sliders 6 to slide along the arc-shaped grooves inside the rotating block 4, ensuring that the rotating block 4 maintains stable axial positioning during fine-tuning and preventing unnecessary lateral displacement. This not only provides precise limiting function, ensuring that the rotating block 4 can only rotate as intended, but also enhances the overall adjustability. To ensure the stability of the connector, both ends of the archwire 1 are equipped with movable segmented sections 9, and one end of the segmented section 9 connected to the archwire 1 is equipped with a pull-out post 10. Both ends of the archwire 1 are equipped with pull-out holes 11 that mate with the pull-out post 10. When slight adjustments to the length of the archwire 1 or overall fine-tuning are needed, the doctor can slightly pull the segmented section 9, causing the pull-out post 10 to slide within the pull-out hole 11. This allows the segmented section 9 and its metal bracket 2 to adjust synchronously, ensuring the flexibility and adaptability of the entire orthodontic appliance. By adjusting the position of the segmented section 9, the overall length and tension of the archwire 1 can be precisely controlled without disassembling or reinstalling the orthodontic appliance, simplifying the adjustment process and improving efficiency. Several damping strips 13 are arranged around the inner wall of the pull-out hole 11.Furthermore, the outer wall of the pull post 10 is provided with several sliding grooves that are adapted to the damping strip 13, and sealing rings 12 are provided at both ends of the archwire 1 at the edges of the pull hole 11. When the segmented part 9 is slightly pulled for adjustment, the damping strip 13 interacts with the sliding grooves on the pull post 10 to provide appropriate resistance, ensuring the smooth movement and precise positioning of the pull post 10 within the pull hole 11. This not only prevents positional displacement caused by excessive pulling or accidental movement, but also makes the adjustment process more controllable and smooth. The outer end of the corresponding side of the elastic clip 5 has an arc-shaped chamfer structure, and the interior of the elastic clip 5 is provided with a weight-reducing groove. When the metal bracket 2 is installed on the archwire 1, the elastic clip 5 can slide smoothly into and engage in the appropriate position of the archwire 1, reducing resistance and possible damage during installation. At the same time, the weight-reducing groove inside the elastic clip 5 not only reduces the overall weight of the elastic clip 5 and reduces the pressure of the orthodontic appliance on the teeth, but also maintains sufficient elasticity to ensure its stability. The metal bracket 2 is securely fixed to the archwire 1 and is not easily loosened. The inner side of the metal bracket 2 has a double-layered cushioning element 14. The inner layer of the cushioning element 14 is memory foam, and the outer layer is soft silicone. The memory foam of the cushioning element 14 uses existing temperature-sensitive and slow-rebound materials, typically polyurethane-based, containing countless tiny air bubbles or cells. These cells can adjust their shape according to changes in external pressure and temperature. When pressure is applied, the cells in the memory foam temporarily deform to adapt to the shape of the pressure source and slowly return to their original shape after the pressure is removed. With this structure, when the metal bracket 2 is fixed to the teeth, the inner layer of memory foam can automatically adjust according to the shape of the teeth and the pressure distribution, providing a personalized fit and ensuring that each bracket is firmly attached to the tooth surface while minimizing pressure on the teeth. The outer soft silicone layer further enhances wearing comfort; its smooth and soft texture effectively prevents irritation and damage to the gums and oral soft tissues.

[0019] Working principle: When using this combination orthodontic appliance, the metal bracket 2 is first secured to the archwire 1 by the elastic clip 5. The curved chamfered structure of the elastic clip 5 helps it slide smoothly into place and be fixed in the appropriate position. Subsequently, according to the patient's tooth alignment and treatment needs, the dentist can adjust the overall length and tension of the archwire 1 by slightly pulling the segment 9. When the pull post 10 slides smoothly within the pull hole 11, the damping strip 13 interacts with the sliding groove on the pull post 10 to provide appropriate resistance, ensuring precise positioning. The sealing ring 12 prevents external impurities from entering. Next, for fine-tuning... At the position of the metal bracket 2, the dentist can rotate the rotating block 4 inside the convex ring 3. The precise adjustment is achieved by utilizing the cooperation between the micro gear 8 and the micro rack 7 inside the rotating block 4. During this process, the arc-shaped sliders 6 on both sides of the convex ring 3 slide along the arc-shaped groove inside the rotating block 4, ensuring the stable axial positioning of the rotating block 4 and avoiding unnecessary lateral displacement. Finally, when all adjustments are completed, the metal bracket 2 is tightly attached to the tooth surface through the double-layer buffer 14. The entire process does not require disassembly or reinstallation of the orthodontic appliance, simplifying the adjustment steps and improving operational efficiency, thus completing a series of tasks.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
