Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, specifically to an orthodontic traction structure. Background Technology

[0002] Orthodontic treatment is necessary for dental and jaw deformities caused by congenital or acquired factors. In orthodontics, intermaxillary traction is often required, and the traction hook, as the carrier for applying traction force, is an important component of the orthodontic appliance. The main purpose of the traction hook in orthodontic treatment is to apply corrective force to move the teeth; therefore, a fixed support point is essential during treatment. Clinically, microscrews are often implanted under the maxillary zygomatic bone, in the buccal shelf area of ​​the mandible, or on the alveolar bone between adjacent teeth. Alternatively, a flat bow can be fitted as the support point for the traction hook. A rubber chain or tension spring is then attached between the support point and the traction hook, using elastic traction to move the teeth.

[0003] In existing technologies, conventional orthodontic traction structures cannot apply traction force between adjacent bases through archwires, thus requiring external traction structures to correct the position between adjacent teeth. Traditional rubber chains or tension springs cannot accurately display the traction force, and the traction force is difficult to adjust, making them very inconvenient to use. Utility Model Content

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.

[0020] Please see Figures 1-4 This utility model discloses an orthodontic traction structure, including a base 1. A rectangular cover 2 is fixedly installed on the front side of the base 1, and the left and right sides of the rectangular cover 2 are open structures. A first mounting ring 3 is fixedly installed between the front and rear inner walls of the rectangular cover 2 and the front side of the base 1 near the left and right edges. An adjustment mechanism 4 is installed on the upper side wall of the rectangular cover 2. A second mounting ring 5 is fixedly installed on the lower surface of the adjustment mechanism 4. An archwire 6 is inserted into the first mounting ring 3 and the second mounting ring 5. A traction ring 7 is provided on the archwire 6. A universal ball head 8 is fixedly installed on the upper surface of the traction ring 7. A monitoring mechanism 9 is installed on the upper surface of the universal ball head 8, and a hook head 10 is installed on the upper surface of the monitoring mechanism 9.

[0021] Specifically, the inner walls of both the first mounting ring 3 and the second mounting ring 5 have rounded corners near their left edges.

[0022] In this embodiment, the first mounting ring 3 and the second mounting ring 5 can better meet the bending requirements of the bowwire 6.

[0023] Specifically, the outer surface of the second mounting ring 5 is a rectangular structure, and the front and rear sides of the second mounting ring 5 are movably fitted with the inner wall of the front side of the rectangular cover 2 or the front side of the base 1.

[0024] In this embodiment, the second mounting ring 5 can stably press the front side of the base 1 to move up and down.

[0025] Specifically, the adjustment mechanism 4 includes a first bolt rod 401 and a bearing assembly 402. The first bolt rod 401 is threaded onto the upper side wall of the rectangular cover 2, and the lower surface of the first bolt rod 401 is connected to the bearing assembly 402. The bearing assembly 402 is mounted on the upper surface of the second mounting ring 5.

[0026] In this embodiment, the first bolt rod 401 moves up and down spirally in the upper side wall of the rectangular cover 2, so that the first bolt rod 401 drives the second mounting ring 5 to move up and down through the bearing assembly 402, and the second mounting ring 5 drives the bow wire 6 to move up and down, thereby achieving the effect of adjusting the traction force of the bow wire 6.

[0027] Specifically, the monitoring mechanism 9 includes a mounting cylinder 901, a spring 902, a movable cylinder 903, a second bolt rod 904, an observation window 905, and a scale line 906. The mounting cylinder 901 is fixedly mounted on the upper surface of the universal ball joint 8. The spring 902 is fixedly mounted on the lower inner wall of the mounting cylinder 901. The upper surface of the spring 902 is fixedly connected to the upper inner wall of the movable cylinder 903. The second bolt rod 904 is threaded onto the upper inner wall of the movable cylinder 903, and the upper surface of the second bolt rod 904 is fixedly connected to the lower surface of the hook head 10. An observation window 905 is provided on the front side wall of the mounting cylinder 901, and a scale line 906 is provided on the front side of the mounting cylinder 901 corresponding to the observation window 905.

[0028] In this embodiment, the movable cylinder 903 moves up and down within the mounting cylinder 901 along with the hook head 10. The movable cylinder 903 drives the spring 902 to unfold, and the spring 902 applies a traction force to the hook head 10. The lower surface of the movable cylinder 903 can be viewed through the observation window 905. The traction force on the movable cylinder 903 can be viewed through the markings on the scale line 906. Then, the second bolt rod 904 moves up and down spirally in the upper side wall of the movable cylinder 903 to adjust the height of the hook head 10 and thus adjust the traction force of the hook head 10.

[0029] Specifically, the upper surface of the mounting cylinder 901 is an open structure, the lower surface of the movable cylinder 903 is an open structure, and the inner wall of the mounting cylinder 901 is movably fitted with the outer surface of the movable cylinder 903.

[0030] In this embodiment, the outer surface of the movable cylinder 903 can move stably up and down along the inner wall of the mounting cylinder 901.

[0031] In use, multiple bases 1 are glued to the teeth. The archwire 6 is then sequentially installed in the first mounting ring 3 and the second mounting ring 5 on the front side of the base 1. The first bolt rod 401 in the adjusting mechanism 4 moves spirally up and down in the upper side wall of the rectangular cover 2, causing the first bolt rod 401 to drive the second mounting ring 5 up and down via the bearing assembly 402. This, in turn, causes the second mounting ring 5 to drive the archwire 6 up and down, thus adjusting the traction force of the archwire 6. The universal ball joint 8 allows the monitoring mechanism 9 and the hook head 10 to face in multiple directions. The hook head 10 is connected to the support point via a rubber chain. The movement is controlled by the movable cylinder 90 in the monitoring mechanism 9. 3. As the hook head 10 moves up and down inside the mounting cylinder 901, the movable cylinder 903 drives the spring 902 to unfold. The spring 902 applies a traction force to the hook head 10, and the lower surface of the movable cylinder 903 can be viewed through the observation window 905. The traction force on the movable cylinder 903 can be checked by the markings on the scale line 906. When it is necessary to adjust the traction force, the rubber chain on the hook head 10 is removed, so that the second bolt rod 904 moves up and down spirally in the upper side wall of the movable cylinder 903 to adjust the height of the hook head 10. Then the rubber chain is put back on to adjust the traction force of the hook head 10 and make the traction effect better.

[0032] In summary, this orthodontic traction structure can adjust the traction force of the archwire 6, thereby correcting the position between adjacent teeth, allowing the hook 10 to face in multiple directions, and monitoring and adjusting the traction force on the hook 10 to achieve better traction results.
