Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to an orthodontic traction device for complex impacted teeth. Background Technology

[0002] The basic principle of impacted tooth traction is to implant a metal or ceramic device in the patient's mouth, connecting it to the patient's teeth or jawbone. This device applies a continuous, gentle force to gradually move the target tooth or expand the bone space, allowing it to move into the correct position. A common method is to place an archwire around a normal tooth, and then place a tension component or traction wire between the archwire and the impacted tooth to achieve the traction purpose.

[0003] Existing impacted tooth traction devices typically use traction ropes to directly pull and traction the impacted tooth. During the traction process, it is difficult to adjust the traction angle, making it difficult for the impacted tooth to grow at the required angle. Furthermore, once the impacted tooth shifts, it will affect the patient's biting ability.

[0004] Therefore, this invention provides an orthodontic traction device for complex impacted teeth to solve the above problems. Utility Model Content

[0013] (III) Beneficial Effects

[0014] 1. This orthodontic traction device for complex impacted teeth comprises brackets, archwires, a moving frame, a first universal joint, a second universal joint, a threaded rod, and a threaded sleeve. During use, rotating the threaded rod, which is threadedly connected to the threaded sleeve, causes the rod to extend or retract along the sleeve. This extension or retraction moves the moving frame along the archwire. Simultaneously, the first and second universal joints can be adjusted at any time to regulate the angle of movement. This allows the traction device to adjust the angle of impacted tooth correction, preventing displacement of the impacted tooth due to direct traction during correction. It also prevents a decrease in occlusal force caused by tooth displacement. Furthermore, the self-locking threads of the threaded rod and sleeve ensure stable correction after the impacted tooth is corrected.

[0015] 2. This orthodontic traction device for complex impacted teeth, by setting up a traction rope, connecting frame, movable frame and fixed seat, allows the position of the impacted tooth to be adjusted by the traction rope when the movable frame moves. At the same time, the cooperation between the movable frame and the connecting frame allows for secondary fine adjustment of the position of the impacted tooth at any time, ensuring the accuracy of the movement of the impacted tooth during orthodontic treatment.

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides an orthodontic traction device for complex impacted teeth, including an impacted tooth 1, with several teeth 2 arranged at the bottom of the impacted tooth 1, and each tooth 2 having a bracket 3 fixedly connected to one end. The brackets 3 are connected by a single archwire 4. Two movable frames 5 are movably connected to the outer wall of the archwire 4. A first universal joint 6 is fixedly connected to the side of each movable frame 5 that is far apart from the other. The first universal joint 6 is rotatably connected to a second universal joint 7. A threaded rod 8 is provided at one end of the second universal joint 7. The outer wall of the threaded rod 8 is threadedly connected to the inner wall of a threaded sleeve 9. One end of the threaded sleeve 9 is connected to the corresponding end of a bracket 3. The device utilizes the bracket 3, archwire 4, movable frames 5, first universal joint 6, second universal joint 7, threaded rod 8, and... In use, the threaded sleeve 9 is rotated by rotating the threaded rod 8. Since the threaded rod 8 and the threaded sleeve 9 are connected by threads, rotating the threaded rod 8 causes the threaded rod 8 to extend or retract along the threaded sleeve 9. During the extension or retraction of the threaded rod 8, the moving frame 5 will move along the archwire 4. At the same time, the first universal joint 6 and the second universal joint 7 can adjust the angle of movement at any time. This allows the traction device to adjust the angle of the impacted tooth 1 during use, avoiding the impacted tooth 1 from shifting due to direct traction during the correction process. It also avoids the impacted tooth 1 shifting and causing a decrease in the patient's biting force. Furthermore, the self-locking of the threads of the threaded rod 8 and the threaded sleeve 9 ensures the stability of the correction after the impacted tooth 1 is corrected.

[0024] The outer wall of the archwire 4 is provided with a first positioning ring 10, and one end of the impacted tooth 1 is fixedly connected to a connecting seat 11. The inner wall of the connecting seat 11 is fixedly connected with a second positioning ring 12. The first positioning ring 10 and the second positioning ring 12 are connected by a traction chain 13. By setting the first positioning ring 10, the second positioning ring 12 and the traction chain 13, the initial position of the impacted tooth 1 and the archwire 4 can be positioned. At the same time, it can play an auxiliary support role in the adjustment of the impacted tooth 1, so as to ensure the stability of the orthodontic treatment of the impacted tooth 1.

[0025] Two fixed seats 14 are fixedly connected to one end of the impacted tooth 1. The two fixed seats 14 are rotatably connected to two movable frames 15 through rotating rods. The movable frames 15 are hinged to two connecting frames 16 through pins. The same first connecting member 17 is fixedly connected to the opposite end of the two connecting frames 16. The movable frame 5 has a groove 18 inside. The inner wall of the groove 18 is fixedly connected to the second connecting member 19 through a connecting shaft. The first connecting member 17 and the second connecting member 19 are connected by a traction rope 20. By setting up the traction rope 20, connecting frames 16, movable frames 15 and fixed seats 14, the position of the impacted tooth 1 can be adjusted by the traction rope 20 when the movable frame 5 moves. At the same time, the cooperation between the movable frame 15 and the connecting frame 16 allows for secondary fine-tuning of the position of the impacted tooth 1 at any time, ensuring the accuracy of the movement of the impacted tooth 1 during correction.

[0026] The movable frame 5 has an internal movable hole 21, which is used in conjunction with the bow wire 4. The inner diameter of the movable hole 21 is larger than the outer diameter of the bow wire 4.

[0027] Working principle:

[0028] In use, rotating the threaded rod 8 causes it to extend or retract along the threaded sleeve 9, as the threaded rod 8 and the threaded sleeve 9 are connected by threads. During the extension or retraction of the threaded rod 8, the moving frame 5 moves along the bow wire 4. At the same time, the first universal joint 6 and the second universal joint 7 can adjust the angle of movement at any time. When the moving frame 5 moves, it will drive the connecting frame 16, the movable frame 15 and the fixed seat 14 to move through the traction rope 20, thereby moving the embedded tooth 1 and thus correcting the position of the embedded tooth 1.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
