Description

Technical Field

[0001] This application relates to the technical field of dental implants, and in particular to a turbine-shaped external connection dental implant system. Background Technology

[0002] In the field of dental implantology, implant stability, osseointegration efficiency, and long-term functional maintenance are key factors determining clinical success. Traditional implant systems generally employ smooth or simple threaded designs, which, while achieving basic retention, have the following limitations:

[0003] Insufficient osseointegration: Traditional implant surface treatment techniques (such as mechanical polishing) have limited contact area, low osteoblast attachment efficiency, long bone healing cycle, and anti-rotation ability depends on the mechanical interlocking of the threads and bone, making it prone to bone resorption due to micromovement.

[0004] Connection structure is prone to loosening: Most implants use a single taper or screw fixation connection, lacking anti-rotation limiting design. Under long-term chewing load, micro-movement or loosening is likely to occur, leading to decreased stability of the prosthesis and even mechanical complications.

[0005] Inconvenient maintenance: Most existing structures are integrated or complex assembly structures. Disassembly requires damaging the connection interface, making modular maintenance difficult and increasing the complexity of clinical operations and patient costs.

[0006] To address the aforementioned issues, this invention proposes a turbine-shaped external dental implant system. This system expands the bone contact interface through a turbine structure, enhances connection stability through multiple self-locking mechanisms, and incorporates a detachable modular design to improve usability. Utility Model Content

[0007] In order to solve the problems existing in the background art, this utility model proposes a turbine-shaped external connection dental implant system.

[0008] The turbine-shaped external dental implant system provided in this application adopts the following technical solution:

[0009] A turbine-shaped external dental implant system includes a dental implant, which comprises an implant body and an articulator. The implant body is for implantation in a dental implant cavity. The implant body is a turbine-shaped cylinder. An articulator is integrally formed on the top of the implant body. The articulator is an upper conical cylinder.

[0010] An external connector includes a hollow connector body, which is a lower conical hollow cylinder. A hollow connector portion is provided on the bottom surface of the hollow connector body. The hollow connector portion and the connector frame are connected and locked together. A hexagonal connector body is integrally formed on the top surface of the hollow connector body. The hexagonal connector body is an upper conical hexagonal structure. A screw fixing hole is provided in the center of the top surface of the hexagonal connector body. The screw fixing hole is connected to the top surface of the hollow connector portion.

[0011] The outer connector is a hollow cylindrical body with an upper conical shape. A hollow hexagonal connecting part is provided in the middle of the bottom surface of the outer connector. The hexagonal connecting part is a hollow hexagonal structure with an upper conical shape. A screw mounting hole is provided in the middle of the upper end of the outer connector. The screw mounting hole and the hexagonal connecting part are connected through a screw through hole.

[0012] The center screw is detachably installed inside the screw mounting hole, and the lower end of the center screw passes through the screw through hole and connects to the screw retaining hole.

[0013] Dentures, which are detachably installed on the external connecting body wall.

[0014] Furthermore, the implant includes turbine blades and a central shaft, with turbine blades uniformly mounted circumferentially on the outer surface of the central shaft.

[0015] Furthermore, the turbine blade is an arc-shaped rectangular plate structure.

[0016] Furthermore, the outer wall of the connector frame is a Morse taper male cone portion, and the inner wall of the hollow connector portion is a Morse taper female cone portion, with the connector frame and the hollow connector portion engaging in a plug-in fit.

[0017] Furthermore, U-shaped pins are evenly arranged on the outer periphery of the plug frame, and U-shaped slots that cooperate with the U-shaped pins are evenly arranged at the lower end of the hollow plug body.

[0018] Furthermore, the outer wall of the hexagonal connector is a male Morse taper portion, and the inner wall of the hexagonal connector is a female Morse taper portion, with the hexagonal connector and the hexagonal connector being inserted into each other.

[0019] Furthermore, the denture has a hollow slot at the bottom, the outer wall of the outer connecting body is a male Morse taper, and the inner wall of the hollow slot is a female Morse taper. The denture is inserted and fitted into the outer wall of the outer connecting body through the hollow slot.

[0020] Beneficial effects

[0021] Compared with the prior art, this utility model provides a turbine-shaped external connection dental implant system, which has the following beneficial effects:

[0022] 1. In this utility model, the turbine blades of the implant are evenly distributed to form a multi-level bone contact interface, which expands the surface area with the bone tissue, promotes the three-dimensional adhesion of osteoblasts, accelerates the bone regeneration and osseointegration process, and forms a mechanical interlock between the gaps between the turbine blades and the bone tissue. Combined with the overall cylindrical turbine shape of the implant, it provides strong resistance to torsional load and reduces the risk of bone resorption caused by micromotion.

[0023] 2. In this utility model, the plug-in frame and the external plug-in body achieve a gapless connection through Morse taper self-locking. At the same time, the U-shaped pin and the slot restrict the degree of rotational freedom and ensure axial stability. The taper matching of the hexagonal connector and the external connector, combined with the pre-tightening force of the central screw, eliminates micro-movement gaps and withstands long-term chewing cycle loads. The hexagonal symmetrical structure evenly distributes the biting force to the implant and surrounding bone tissue, avoiding local stress concentration, reducing the risk of mechanical fatigue fracture, and extending the service life of the system.

[0024] 3. In this utility model, the external connector, external connector and denture can all be disassembled independently. When it is necessary to adjust the shape of the prosthesis or replace damaged parts during or after the operation, there is no need to remove the implant, which reduces the trauma of secondary surgery. The Morse taper insertion combined with the mechanical limiting structure simplifies the clinical operation process, achieves precise alignment between components and shortens the operation time.

[0034] 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.

[0035] Please see Figure 1-7 This utility model provides a turbine-shaped external connection dental implant system, including a dental implant 1, which includes an implant body 11 and a connector 12. The implant body 11 is used for implantation in the dental implant cavity and is a turbine-shaped cylinder. The connector 12 is integrally formed on the top of the implant body 11 and is an upper conical cylinder. The external connector 2 includes a hollow connector 21, which is a lower conical hollow cylinder. A hollow connector portion 22 is provided on the bottom surface of the hollow connector 21. The hollow connector portion 22 is inserted and locked with the connector 12. A hexagonal connector 23 is integrally formed on the top surface of the hollow connector 21 and is an upper conical hexagon. The structure includes a hexagonal connector 23 with a screw retaining hole 24 at the center of its top surface, which communicates with the top surface of the hollow insertion part 22; an outer connector 3 is an upper conical hollow cylinder with a hollow hexagonal connector 31 at the center of its bottom surface, the hexagonal connector 31 being an upper conical hollow hexagonal structure, and a screw mounting hole 32 at the center of the upper end of the outer connector 3, the screw mounting hole 32 and the hexagonal connector 31 being connected through a screw through hole 33; a central screw 4 is detachably installed inside the screw mounting hole 32, the lower end of the central screw 4 passing through the screw through hole 33 and connecting to the screw retaining hole 24; and a denture 5 is detachably installed on the outer wall of the outer connector 3.

[0036] In the above technical solution, the implant 11 is used to be implanted in the dental implant socket. After bone healing, the implant 11 can integrate with the bone. The implant 11 is a turbine-shaped cylinder, which enables the implant 11 to obtain strong retention force and anti-rotation force, thereby improving the stability of the dental implant. The external connector 2 is installed on the connector frame 12 by plugging. The external connector 3 is installed on the hexagonal connector 23 by plugging. The external connector 2 and the external connector 3 are locked and fixed by the central screw 4. The denture 5 is detachably installed on the outer wall of the external connector 3, which facilitates the installation, removal and maintenance of the external connector 2, the external connector 3 and the denture 5, improves the convenience of use and enhances the aesthetics.

[0037] See Figures 1-4As shown, as a preferred technical solution of this embodiment, the implant 11 includes turbine blades 13 and a central shaft 14, and turbine blades 13 are uniformly installed on the outer side of the central shaft 14 along its circumference.

[0038] See Figures 1-4 As shown, as a preferred technical solution in this embodiment, the turbine blade 13 is an arc-shaped rectangular plate structure. The turbine blade 13 is made of biocompatible materials, such as titanium and its alloys, which have excellent biocompatibility and low rejection reaction. The surface of the turbine blade 13 has a certain roughness. Moderate roughness (such as sandblasting, acid etching, SLA, or anodizing) increases the contact area and can promote osteoblast attachment.

[0039] In the above technical solution, the turbine blades 13 are evenly arranged on the outside of the central shaft 14. After the turbine blades 13 are implanted in the dental implant cavity, the turbine blades 13 can facilitate the attachment of osteoblasts. The osteoblasts in the gaps between adjacent turbine blades 13 guide regeneration, and the surface of each turbine blade 13 combines with the osteoblasts, thereby enabling the entire dental implant 1 to obtain strong retention and anti-rotation force.

[0040] See Figures 4-6 As shown, in this preferred embodiment, the outer wall of the plug-in frame 12 is a Morse taper male cone portion, and the inner wall of the hollow plug-in portion 22 is a Morse taper female cone portion. The plug-in frame 12 and the hollow plug-in portion 22 are plugged into each other.

[0041] See Figures 4-6 As shown, in this preferred embodiment, U-shaped pins 15 are evenly arranged on the outer periphery of the plug frame 12, and U-shaped slots 25 that cooperate with the U-shaped pins 15 are evenly arranged at the lower end of the hollow plug body 21.

[0042] In the above technical solution, after the plug-in frame 12 and the hollow plug-in part 22 are plugged in, they fit together and can achieve Morse taper self-locking connection and fixation. At the same time, through the one-to-one correspondence and mutual fit between the U-shaped slot 25 and the U-shaped pin 15, after the outer plug-in body 2 and the plug-in frame 12 are self-locked and fixed, a sliding connection and limit braking can be achieved. That is, the outer plug-in body 2 can only slide up and down along the plug-in frame 12, and there will be no relative rotation between the outer plug-in body 2 and the plug-in frame 12.

[0043] See Figure 6 As shown, in this preferred embodiment, the outer wall of the hexagonal connector 23 is a Morse taper male cone portion, the inner wall of the hexagonal connector 31 is a Morse taper female cone portion, and the hexagonal connector 23 and the hexagonal connector 31 are inserted into each other.

[0044] In the above technical solution, the hexagonal connector 23 and the hexagonal connector 31 fit together after insertion, which can achieve Morse taper self-locking connection and fixation. No micro-movement will occur between the hexagonal connector 23 and the hexagonal connector 31. After they fit together, under the locking bone screw of the central screw 4, they can achieve Morse taper connection and fixation, ensuring the stability of the connection and avoiding gaps between the hexagonal connector 23 and the hexagonal connector 31, preventing foreign objects from entering the gap. At the same time, the stress distribution between the hexagonal connector 23 and the hexagonal connector 31 is uniform and the tolerance is high.

[0045] See Figure 1 As shown, in this preferred embodiment, the denture 5 has a hollow slot 51 at its bottom, the outer wall of the outer connector 3 is a male Morse taper, and the inner wall of the hollow slot 51 is a female Morse taper. The denture 5 is inserted into the outer wall of the outer connector 3 through the hollow slot 51.

[0046] In the above technical solution, when the denture 5 is installed on the outer wall of the outer connector 3, the denture 5 and the outer connector 3 can achieve a Morse taper self-locking connection and fixation. No micro-movement will occur between the denture 5 and the outer connector 3. The denture 5 can be detached, which facilitates the installation, removal and maintenance of the denture 5.

[0047] The working principle of this utility model is as follows:

[0048] S1: Implant fixation and osseointegration

[0049] The turbine-shaped implant 11 is inserted into the dental implant cavity. The turbine pieces 13 are evenly distributed on the outside of the central axis 14. The turbine-shaped structure expands the contact area with the bone tissue. The gaps between adjacent turbine pieces guide bone cell regeneration and form a three-dimensional bone integration network. After bone healing, the turbine pieces 13 fit tightly with the surrounding bone tissue, providing strong initial mechanical retention and anti-rotation performance, ensuring the long-term stability of the implant 11 in the jawbone.

[0050] S2: External connector self-locking connection and limiting function

[0051] The external connector 2 is inserted into the connector frame 12 via Morse taper matching: the outer wall (male taper) of the connector frame 12 precisely matches the inner wall (female taper) of the hollow connector 22, forming a self-locking fixation; at the same time, the U-shaped pins 15 on the connector frame 12 are inserted one-to-one with the U-shaped slots 25 at the bottom of the hollow connector 21 to achieve sliding limit, preventing relative rotation between the external connector 2 and the implant 1, allowing only axial fine adjustment; this design combines taper self-locking and mechanical limit to ensure stable connection and facilitate precise alignment of subsequent components.

[0052] S3: External Connector Hexagonal Locking and Stress Distribution

[0053] The outer connector 3 is inserted into the hexagonal connector 23 via the hexagonal connector 31: the outer wall (male cone) of the hexagonal connector 23 and the inner wall (female cone) of the hexagonal connector 31 are matched with Morse taper to eliminate micro-movement gaps; then, the center screw 4 is passed through the screw mounting hole 32 and the screw through hole 33, screwed into the screw retaining hole 24 and tightened to generate axial preload, further strengthening the conical surface fit; the symmetrical design of the hexagonal structure makes the interlocking force evenly distributed to the outer connector 2 and the implant 1, avoiding local stress concentration, and improving the system's resistance to lateral loads and long-term durability.

[0054] S4: Modular installation and aesthetic fit of dentures

[0055] The denture 5 is inserted into the outer wall (male cone) of the outer connector 3 through the hollow slot 51 at the bottom, and is firmly fixed by the self-locking of the Morse taper; the denture 5 can be disassembled independently, which is convenient for adjustment or maintenance without disturbing the underlying implant structure; the seamless fit between the tapered outer wall of the outer connector 3 and the inner wall of the denture enhances mechanical stability and ensures a high degree of unity between function and aesthetics.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
