Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, specifically to an orthodontic anchorage screw with a double-ring buffer structure protective sleeve. Background Technology

[0002] Orthodontics is the process of straightening teeth and correcting malocclusions and deformities. Orthodontics can achieve aesthetically pleasing teeth. The duration of orthodontic treatment varies depending on the severity of the malocclusion, but even for children with relatively mild deformities, at least 6 months of treatment is required, while adult orthodontics typically takes 2-3 years. This is because current orthodontic methods use a mechanical means—aligners—that adjust at regular intervals to ultimately achieve a neat and aesthetically pleasing alignment of teeth.

[0003] Currently, when patients use orthodontic anchorage screws for adjunctive therapy, the screw tips are usually made of metal with structural features on the surface. This friction during daily activities such as speaking, chewing, and brushing teeth can cause mucosal ulcers or bleeding. Additionally, the connection between the anchorage screw and the gum can create sores, easily leading to inflammation and ulceration, causing additional pain for the patient. Therefore, this paper proposes an orthodontic anchorage screw with a double-ring buffer structure protective sleeve. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an orthodontic anchorage screw with a double-ring buffer structure protective sleeve, including a protective sleeve body 1 and an anchorage screw 2. The anchorage screw 2 is composed of a threaded rod 3, an anchorage screw head 4, an anchorage screw neck 5, and an anchorage screw nut 6. The lower end of the anchorage screw nut 6 is fixedly connected to the threaded rod 3. The top of the anchorage screw nut 6 is provided with the anchorage screw head 4. The anchorage screw neck 5 is provided between the anchorage screw nut 6 and the anchorage screw head 4. The protective sleeve body 1 is sleeved and connected to the top of the anchorage screw 2. The protective sleeve body 1 includes an outer protective sleeve 7 and an inner protective sleeve 8. The outer protective sleeve 7 covers the surface of the inner protective sleeve 8. The center of the inner protective sleeve 8 is provided with a sleeve hole 9. The surface of the outer protective sleeve 7 is provided with an upper buffer ring 10 and a lower buffer ring 11. The upper buffer ring 10 is located at the top of the outer protective sleeve 7, and the lower buffer ring 11 is located at the bottom of the outer protective sleeve 7.

[0022] Further improvements include a raised fastening ring 12 on the inner wall of the socket 9, which engages with the neck 5 of the anchor nail. By providing a raised fastening ring 12 inside the socket 9, the stability of the connection between the protective sleeve body 1 and the anchor nail 2 is improved.

[0023] Further improvements include a filling cavity 13 inside the lower buffer ring 11, and uniformly distributed capillary pores 14 on the surface of the lower buffer ring 11. By providing a filling cavity 13 inside the lower buffer ring 11, it is convenient to inject anti-inflammatory and antibacterial drugs into the lower buffer ring 11. Combined with the capillary pores 14 on the surface, it is easy for the drugs to slowly overflow, effectively relieving inflammation and ulceration at the implantation site of the anchorage nail 2.

[0024] Further improvements include a smooth transition between the surface of the upper buffer ring 10 and the outer protective sleeve 7, which reduces discomfort from contact between the lip and the anchor pin 2, while preventing excessive friction of the lip during activity that could lead to mucosal ulcers or bleeding.

[0025] Further improvements include annularly distributed slits 15 on the sidewall of the inner protective sleeve 8, and slits 16 corresponding to the slits 15 on the sidewall of the outer protective sleeve 7. By providing slits 15 on the sidewall of the inner protective sleeve 8, deformation is facilitated when disassembling and assembling the protective sleeve body 1, and rubber bands are also easily installed at the neck of the anchor nail, thus improving ease of use.

[0026] Specifically, the inner protective sleeve 8 is made of medical-grade plastic through one-piece injection molding, and the outer protective sleeve 7 is made of silicone. The outer protective sleeve 7 is fixedly connected to the inner protective sleeve 8. By using medical-grade plastic for the inner protective sleeve 8, the stability of the connection with the end of the anchorage screw 2 is improved, preventing it from falling off during use. By using silicone for the outer protective sleeve 7, the comfort of the patient is effectively improved.

[0027] In use, the protective sleeve body 1 is directly sleeved onto the surface of the anchorage nail 2. The inner protective sleeve 8 has a protruding fastening ring 12 that fastens with the neck 5 of the anchorage nail, preventing the protective sleeve body 1 from falling off when the patient speaks, chews, or brushes their teeth. The lower buffer ring 11 at the lower end of the outer protective sleeve 7 wraps around the connection between the anchorage nail 2 and the gum, sealing the wound and reducing the seepage of food or saliva into the area around the wound. Combined with the medication injected inside the lower buffer ring 11, it can continuously reduce inflammation at the wound and alleviate the patient's pain. The upper buffer ring 10 at the upper end of the outer protective sleeve 7 supports the patient's lips, preventing mucosal ulcers or bleeding caused by friction when the patient speaks, chews, or brushes their teeth.

[0028] This invention addresses the problem that when patients use anchorage screws for adjunctive therapy, the screw ends are typically made of metal and have structural features on their surface. Friction during daily activities such as speaking, chewing, and brushing can cause mucosal ulcers or bleeding. Additionally, the connection point between the anchorage screw and the gums can create sores, easily leading to inflammation and ulceration, causing additional pain. This invention addresses this issue by attaching a protective sleeve body 1 to the top of the anchorage screw 2, preventing direct contact between the anchorage screw 2 and the lips. Combined with the upper and lower buffer rings 10 and 11 on the surface of the protective sleeve, it effectively prevents mucosal ulcers or bleeding caused by friction during speaking, chewing, and brushing. Furthermore, it reduces inflammation at the contact point between the anchorage screw 2 and the gums, preventing infection and inflammation at the sores.
