Description

Technical Field

[0001] This utility model relates to the technical field of implant nail combined with arch expander, specifically an easily adjustable implant nail combined with arch expander. Background Technology

[0002] With the improvement of living standards, having a set of straight, white teeth has become the pursuit of more and more people. Malocclusion affects appearance and can also impact mental and physical health. Crowded upper teeth are the most common cause of malocclusion, and the direct cause is usually insufficient maxillary development, resulting in an excessively narrow dental arch. An overly narrow dental arch causes teeth to concave forward or inward, or even overlap, preventing them from forming a natural arc shape. Protruding canines are the most common manifestation of crowded teeth. Crowded teeth make brushing difficult, increase cavities, and easily accumulate plaque and tartar. In severe cases, it can lead to gingivitis, periodontitis, and ultimately, tooth loosening and loss. While arch expanders are needed for correction, existing implant-supported expanders are difficult to adjust after implantation, making the procedure inconvenient.

[0003] Therefore, a conveniently adjustable implant-supported expander is needed to improve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a conveniently adjustable implant nail combined with an arch expander to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0024] An easily adjustable implant peg combined with an arch expander includes a left tray 1, a right tray 2 located to the right of the left tray 1, an adjustment component 3 located between the left tray 1 and the right tray 2, a threaded hole 4 located in the middle of the interior of the left tray 1 and the right tray 2, a first sliding hole 5 located on the front side of the interior of the left tray 1 and the right tray 2, and a second sliding hole 6 located on the rear side of the interior of the left tray 1 and the right tray 2, a threaded rod 7 threaded inside the threaded hole 4, a first guide rod 8 slidably located between the two first sliding holes 5, a second guide rod 9 slidably located between the two second sliding holes 6, a first connecting rod 10 symmetrically located on the front side of the bottom of the left tray 1 and the right tray 2, and a second connecting rod 11 symmetrically located on the rear side of the bottom of the left tray 1 and the right tray 2, a first fixing ring 12 located at the upper end of the first connecting rod 10, and a second fixing ring 13 located at the upper end of the second connecting rod 11;

[0025] In this embodiment, the adjustment component 3 includes an adjustment seat 301, a drive worm gear 302 is rotatably disposed on the rear side inside the adjustment seat 301, a drive worm 303 is rotatably disposed on the front side inside the adjustment seat 301, and an adjustment knob 304 is disposed on the front side of the base surface of the adjustment seat 301.

[0026] The drive worm 303 is meshed with the drive worm wheel 302. When the drive worm 303 rotates, it drives the drive worm wheel 302 to rotate. The inner ends of the threaded rod 7 are connected to the left and right ends of the drive worm wheel 302 via connecting shafts. When the drive worm wheel 302 rotates, it drives the threaded rod 7 to rotate. The bottom of the adjusting knob 304 is connected to the upper end of the drive worm 303 via a connecting shaft. The first connecting rod 10 and the second connecting rod 11 are both arc-shaped. The left tray 1 and the right tray 2 have the same structure, allowing for convenient adjustment. The planting nail combined with the bow expander is equipped with an adjustment component 3. During adjustment, only the adjustment knob 304 needs to be turned. When the adjustment knob 304 is turned, the drive worm 303 is rotated. The drive worm 303 drives the drive worm wheel 302 to rotate, which in turn drives the threaded rod 7 to rotate. With the cooperation of the first guide slide 8 and the second guide slide 9, the left tray 1 and the right tray 2 are moved respectively. Therefore, the adjustment is more convenient. The overall device has a simple structure, is easy to operate, and has higher practicality.

[0027] The working process of this utility model is as follows: When using the easily adjustable planting nail combined with arch expander, when adjusting the position of the left tray 1 and the right tray 2, the adjustment knob 304 is rotated. When the adjustment knob 304 rotates, it drives the drive worm gear 303 to rotate. Since the drive worm gear 303 is meshed with the drive worm wheel 302, the drive worm gear 303 drives the drive worm wheel 302 to rotate. When the drive worm wheel 302 rotates, it drives the threaded rod 7 to rotate. Since the threaded rod 7 is threadedly connected to the threaded hole 4, and the first guide slide rod 8 and the second guide slide rod 9 are slidably connected to the first guide slide rod 8 and the second guide slide rod 9 respectively, the left tray 1 and the right tray 2 are moved respectively under the cooperation of the first guide slide rod 8 and the second guide slide rod 9, making it more convenient to adjust.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
