Description

Technical Field

[0001] This utility model relates to oral medicine and dental restoration technology, specifically to prefabricated dental implants. Background Technology

[0002] Currently, most dental implant structures involve pre-embedding an implant in the alveolar bone, then installing an abutment on top, which protrudes from the alveolar bone surface, and finally attaching a corresponding implant crown to achieve prosthetic restoration. However, the connections between implant components are not tight and stable enough, and the seal is poor, making it easy for bone fragments and soft tissue to fall into the gaps between them. After prolonged use, this not only causes wear but also leads to loosening and detachment of the connections, resulting in a short lifespan. Furthermore, most implants are closed structures, making it difficult to add other bioactive molecules or other beneficial substances once implanted. In addition, they are susceptible to loosening and detachment under alternating forces. Especially if they loosen and shift during installation, they cannot spring back to their original position or be retightened, resulting in significant waste. These technical problems directly affect the clinical application results and have become technical bottlenecks that need to be overcome. Utility Model Content

[0003] The technical problem this invention aims to solve is that traditional dental implant systems often suffer from insufficient stability in osseointegration with the alveolar bone and inadequate connection between the crown and the abutment. This solution improves existing dental implant systems to enhance their stability and lifespan.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: prefabricated dental implant, comprising:

[0005] Implants are pre-installed on the alveolar bone. The implant has threaded holes inside and a hollow cavity between the outer and inner walls. Spiral tubing is machined from top to bottom inside the cavity, and liquid nozzles that communicate with the inner cavity of the tubing are integrally formed at equal intervals on the tubing.

[0006] The column base has a threaded column with a specification that matches the threaded hole, which is integrally formed at the bottom. The threaded column and the threaded hole are assembled and connected. A vertically set partition is machined on the upper part of the column base. A triangular block-shaped clip is connected to each end of the partition by a spring.

[0007] The base has a slot machined inside, which matches the specifications of the clips. When the upper part of the column is connected to the slot, the two clips contact the slot opening and press the spring two towards the partition until the two clips are locked in the slot. The upper part of the base is a tooth crown machined in one piece.

[0008] The advantages of this invention compared to existing technologies are as follows: the spiral tubing and liquid nozzle within the abutment enable uniform distribution of bioactive substances, enhancing the stability of osseointegration; simultaneously, the adaptive connection structure between the post and the abutment ensures a tight connection between the crown and the implant; furthermore, the design of the spring and sealing sleeve improves the comfort and lifespan of the implant crown.

[0009] Furthermore, the end of the tubing is equipped with a liquid inlet. Bioactive substances are injected into the inner cavity of the tubing through the liquid inlet and flow downwards while flowing out from liquid nozzles at different positions. This evenly fills the micro-gap between the implant and the alveolar bone, increases the stability of the connection between the implant and the alveolar bone, and promotes the flow of bone fragments and soft tissues in the implant cavity, enabling them to form a good osseointegration with the pre-implanted implant.

[0010] Furthermore, a spring is fitted on the upper part of the abutment, and the lower end of the spring is set on the abutment. The upper end of the spring contacts the crown. The spring is used to counteract the alternating stress generated when the crown contacts food.

[0011] Furthermore, the base is fitted with a matching sealing sleeve, which is a hollow, oral silicone rubber bushing structure. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Example 1

[0022] In this implementation, such as Figures 1 to 7 As shown, a prefabricated dental implant solution is provided, which structurally includes:

[0023] Implant 3: Pre-implanted into the alveolar bone, with threaded holes 9 and spiral tubing 4 machined inside. Multiple liquid nozzles 5, which communicate with the internal cavity, are integrally machined at equal intervals on the tubing 4.

[0024] Column 15: The lower part is integrally formed with a threaded column 8 whose specifications are compatible with the threaded hole 9. The upper part of the column 15 is machined with a vertically set partition 12, and the two ends of the partition 12 are respectively connected to a triangular block-shaped clip 13 by spring 2 14.

[0025] Base 7: Internally machined with a slot 11 that matches the specifications of the clip 13. The upper part of the base 7 is a one-piece molded crown 1.

[0026] Spring 10: It is fitted on the upper end of the base 7, with the lower end set on the base 7 and the upper end in contact with the crown 1, and is used to resist the alternating stress generated when the crown 1 comes into contact with food.

[0027] Sealing sleeve 2: This is a hollow, oral silicone rubber sleeve structure that is fitted onto the outside of the abutment 7 to keep the implant structure clean and hygienic.

[0028] Example 2

[0029] Based on Embodiment 1, in this embodiment, as follows: Figure 1 , Figure 2 and Figure 3 As shown, implant 3 needs to be placed in a suitable location on the patient's alveolar bone under local anesthesia. An incision is made at the selected location using a scalpel blade to expose the alveolar bone. A hole is drilled in the alveolar bone to ensure the depth and diameter of the cavity are compatible with implant 3. Implant 3 is inserted into the cavity, and a cover screw is tightened into implant 3 using a specialized screwdriver to seal it. The wound is sutured, completing the implant 3 placement.

[0030] Example 3

[0031] Based on Embodiment 2, in this embodiment, as follows: Figure 4 , Figure 5 and Figure 6As shown, when connecting the post 15 to the implant 3, apply an appropriate amount of dental adhesive to the threaded hole 9 of the implant 3. Align the threaded post 8 of the post 15 with the threaded hole 9 of the implant 3, and rotate the post 15 to make it tightly connected to the implant 3. When the upper end of the post 15 contacts the slot 11 of the abutment 7, the two retainers 13 will be squeezed by the opening of the slot 11 and compress the spring 14 towards the partition 12. Continue to rotate the post 15 until the two retainers 13 slide smoothly into the slot 11, achieving a stable connection between the post 15 and the abutment 7.

[0032] Example 4

[0033] Based on Embodiment 3, in this embodiment, as follows: Figure 4 , Figure 5 and Figure 6 As shown, when the crown 1 is installed and connected to the abutment 7, a spring 10 is fitted onto the upper end of the abutment 7, ensuring that the lower end of the spring 10 is tightly attached to the abutment 7. The crown 1 is integrally formed and connected to the upper part of the abutment 7, ensuring that the spring 10 is correctly positioned and in close contact with the crown 1.

[0034] Example 5

[0035] Based on Example 4, in this example, as Figure 1 and Figure 6 As shown, a biological agent needs to be injected into implant 3. Using a syringe, the biological agent is injected into tubing 4 through the inlet 6 of implant 3. Ensure the biological agent evenly fills the weak points and gaps in the bone between implant 3 and the gingiva, increasing the stability of the connection with the bone.

[0036] Example 6

[0037] Based on Example 5, in this example, as Figure 5 As shown, the matching sealing sleeve 2 is fitted onto the outside of the abutment 7, ensuring a tight fit between the sealing sleeve 2 and the abutment 7 and the crown 1, maintaining the cleanliness and hygiene of the dental implant system. The installation of the sealing sleeve 2 needs to be performed before the crown 1 is installed onto the implant 3 through the abutment 7. The sealing sleeve 2 is also placed inside the gum line, effectively preventing food and other debris from entering the gap.

[0038] Example 7

[0039] Based on embodiments one through five, in this embodiment, as follows: Figures 1 to 6As shown, the prefabricated dental implant with the above structure meets the mechanical performance requirements of teeth during use. It allows the newly formed bone tissue, bioactive molecules, bone fragments, and implant 3 to form a stable structural whole, promoting biocompatibility while meeting the mechanical performance requirements of the teeth, improving lifespan and implantation comfort, and increasing the stability and anti-rotation performance of the implant. Furthermore, the spring 10 effectively buffers the alternating stress on the crown 1, effectively solving the problem of displacement and loosening that occurs in traditional dental implant crowns under long-term direct stress.
