Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to a dental implant with an antibacterial structure. Background Technology

[0002] Dental implants, also known as dental implants or artificial tooth roots, are a component of dental implants. They are devices surgically implanted into the alveolar bone to provide support and retention for prostheses. They possess good biocompatibility and corrosion resistance. Their working principle involves providing stable support through osseointegration with the alveolar bone. The surgery is relatively minimally invasive. Post-operative care requires attention to oral hygiene and regular follow-up appointments. While widely applicable, some risks still exist. Patients should communicate fully with their dentist and follow their treatment and care recommendations. They are made from materials such as metals, ceramics, glassy carbon, and acrylics.

[0003] According to Chinese patent CN221888425U, a dental implant with an antibacterial structure includes an implant outer tube. The outer wall of the implant outer tube is fixedly connected with a connecting thread, and the outer wall of the implant outer tube has an outer tube fixing port. The inner wall of the implant outer tube is threadedly connected to an implant inner tube, and the inner wall of the implant inner tube is threadedly connected to a threaded plug. The upper outer surface of the threaded plug has a connecting port. When using this device, the implant inner tube and the threaded plug in the dental implant can cooperate with each other, so that the injection plug connected to the inner wall of the implant inner tube can be pushed out by rotating the threaded plug, thereby further strengthening the connection between the dental implant and the alveolar bone and making it less prone to loosening. Antibacterial drugs can be injected through the injection port and flow out through the outlet port, and then flow into the connection gap between the dental implant and the alveolar bone through the drainage channel. This can effectively prevent the growth of bacteria on the outer wall of the dental implant, thereby affecting the user's health.

[0004] The drug delivery device, consisting of the injection port, dispensing port, drainage groove, and external tube fixing port, is a single-use device. Since the implant is placed on the alveolar bone for a long time and the antibacterial time is uncertain, after a single administration, the crown needs to be removed multiple times for re-administration, which is quite troublesome.

[0005] In addition, the traditional method of implant antibacterial treatment involves inserting a needle into the gum line to add antibiotics to the medication bag pre-installed in the implant, which increases the burden on the patient.

[0006] Therefore, to solve the above problems, a dental implant with an antibacterial structure was designed. Utility Model Content

[0007] The main objective of this invention is to provide a dental implant with an antibacterial structure, thereby solving the problems mentioned in the background section.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] An antibacterial dental implant includes an implant tip and an implant base. A fluid reservoir is provided in the inner cavity of the implant tip. A short rod is provided on the outer wall of the fluid reservoir. A rotating ring is provided at the end of the short rod away from the fluid reservoir. A leakage micropore is formed on the bottom wall of the fluid reservoir. An implant base is integrally formed on the outer bottom of the implant tip.

[0010] Furthermore, the reservoir ring is made of elastic soft rubber, and the reservoir ring is fixed to the inner wall of the implant tip by a fixing tape.

[0011] Furthermore, the upper and lower walls of the rotating ring are provided with sealing layers, and the rotating ring is installed in a sealed manner with the inner wall of the implant end through the sealing layers.

[0012] Furthermore, the leakage micropore has a self-closing structure, and a leakage groove penetrating the end of the implant is provided directly below the leakage micropore.

[0013] Furthermore, a base pile mounting groove is provided at the top center of the implant end, and an injection hole is embedded in the implant end on one side of the base pile mounting groove. The injection hole is made of solid rubber and is integrally connected to the liquid storage ring.

[0014] Furthermore, both the implant tip and the implant base are made of titanium alloy.

[0015] The beneficial technical effects of this utility model are as follows:

[0016] This invention incorporates a liquid reservoir ring with an elastic structure within a traditional implant. The reservoir ring stores antibacterial solution within its inner cavity and has micro-holes at its bottom. The reservoir ring is connected to a rotating ring via a short rod. Rotation of the rotating ring compresses the internal space of the reservoir ring through the short rod, increasing internal pressure and causing the antibacterial solution to flow out through the micro-holes. This solution then evenly covers the threaded structure of the implant along the micro-holes, contacting the surrounding alveolar bone tissue and effectively killing bacteria. Releasing the rotating ring restores the reservoir ring's shape, and the micro-holes automatically close, effectively locking in the solution and achieving a rational distribution of the antibacterial solution.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0025] like Figures 1-5 As shown, this embodiment provides an oral implant with an antibacterial structure, including an implant tip 2 and an implant base 1. A liquid reservoir 5 is provided in the inner cavity of the implant tip 2. A short rod 6 is provided on the outer wall of the liquid reservoir 5. A rotating ring 4 is provided at the end of the short rod 6 away from the liquid reservoir 5. A leakage micropore 9 is formed on the bottom wall of the liquid reservoir 5. The implant base 1 is integrally formed on the outer bottom of the implant tip 2.

[0026] The reservoir ring 5 is made of elastic soft rubber. The reservoir ring 5 is fixed to the inner wall of the implant end 2 by the fixing tape 10. The side wall of the reservoir ring 5 facing the short rod 6 is fixed to the inner wall of the implant end 2 by the fixing tape 10. Therefore, the other side wall can be squeezed by the short rod 6 that rotates around it. After deformation, the internal pressure changes, the micropore structure of the leakage micropore 9 is opened, and the medicine flows out to realize the drug administration. The leakage micropore 9 has the same function as the aeration tube in aerating water and preventing backflow.

[0027] In the above embodiment, the liquid storage ring 5 is a structure similar to a swimming ring or the inner band of a tire. It has the property of elastic deformation. After the short rod 6 is driven by the rotating ring 4, it can squeeze the outer wall of the liquid storage ring 5, causing deformation inside the liquid storage ring 5. As a result, the internal pressure changes, the leakage micropore 9 opens, and the antibacterial liquid seeps out.

[0028] The upper and lower walls of the rotating ring 4 are equipped with sealing layers. The rotating ring 4 is installed in a sealed manner with the inner wall of the implant tip 2 through the sealing layers. The sealing layers prevent oral fluid from entering the implant. The outer wall of the rotating ring 4 fits into the outer wall of the implant tip 2 and is made of the same material. When it is moved into the alveolar bone along with the implant, the implant tip 2 and the rotating ring 4 are wrapped in the gum. The user can rotate it by squeezing the gum. Because the amount of medication is small, the squeezing range of the gum is small, and the burden on the user can be minimized.

[0029] The leakage micropore 9 has a self-closing structure, and a leakage groove 7 that penetrates the implant end 2 is provided directly below the leakage micropore 9.

[0030] A post mounting groove 8 is provided at the center of the top of the implant end 2. An injection hole 3 is embedded in the implant end 2 on one side of the post mounting groove 8. The injection hole 3 is made of solid rubber and is integrally connected with the reservoir ring 5. The injection hole 3 is made of the same material as the rubber bottle mouth of the infusion bottle. It can be injected by puncture and also serves as a seal. When replenishing medication, the abutment and crown need to be removed from the post mounting groove 8.

[0031] Both the implant tip 2 and the implant base 1 are made of titanium alloy.

[0032] The working principle of this device is as follows: When in use, the reservoir ring 5 is sealed inside the implant tip 2 by the fixing tape 10, and the outer ring is connected to the rotating ring 4 by the short rod 6. Antibacterial solution is injected into the reservoir ring 5 through the injection hole 3. Then, a hole is made in the alveolar bone, and the implant base 1 is inserted into the hole. The implant tip 2 is located in the gingiva. Then, the abutment and crown are installed on the abutment mounting slot 8, and the bottom of the abutment is pressed against the injection hole 3.

[0033] In practice, since the gingiva covers the implant tip 2, the rotating ring 4 is also located inside the gingiva. However, the rotating ring 4 can be rotated by squeezing the gingiva, which reduces the burden on the patient compared to direct gingival puncture for medication injection. After rotation, the short rod 6 rotates and surrounds the outer body of the compression reservoir ring 5, causing it to deform. As the internal pressure increases, the leakage micropores 9 at the bottom open outwards, simulating the air outlet of an aeration tube. The antibacterial solution flows out to the bottom of the implant tip 2 and then flows outwards through the leakage channels 7. The leakage channels 7 are evenly distributed at the bottom of the implant tip 2, allowing the solution to flow from all sides into the threads of the implant base 1, covering the surrounding alveolar bone and gingival tissue, thus achieving a more effective bactericidal effect. This method not only saves on the amount of medication used and increases the frequency of using the stored medication, but also reduces the number of times the solution needs to be replenished and reduces the workload of crown removal.

[0034] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
