Description

Technical Field

[0001] This invention relates to the field of dental implant technology, and more specifically, to a dental implant suitable for immediate implantation and immediate restoration. Background Technology

[0002] Dental implant restoration involves inserting an implant into the alveolar bone to support the upper prosthesis, and it is the preferred method of restoration after tooth loss. Immediate implantation refers to placing the implant into the unhealed alveolar socket immediately after tooth extraction. If the prosthesis is then directly attached to the implant at the same time, it is called immediate restoration. Immediate implantation and restoration after tooth extraction has become a popular dental implant technique in recent years. Because the alveolar socket is immediately empty after tooth extraction, filled only with blood clots, the implant needs to be inserted deep into the alveolar bone at the bottom of the socket. The initial stability of the implant is achieved by screwing the implant's root tip into the alveolar bone, ensuring the implant does not loosen and stably supports the upper prosthesis. However, this procedure is highly sensitive and difficult to control, especially in cases of insufficient alveolar bone volume or osteoporosis, making it difficult to achieve ideal initial implant stability and thus preventing immediate restoration. Summary of the Invention

[0003] In response to the shortcomings of existing technologies, this invention innovatively provides a dental implant suitable for immediate implantation and immediate restoration, which can solve the technical problems of implants being prone to loosening and unable to achieve immediate restoration in existing technologies.

[0004] To achieve the above-mentioned technical objectives, this invention discloses a dental implant suitable for immediate implantation and immediate restoration, comprising:

[0005] An implant, comprising a body and a tip, wherein the body is a cylindrical structure and the tip is disposed at a first end of the body.

[0006] The outer peripheral wall of the body has an external thread, and the interior of the body has a threaded hole extending axially. A connecting groove is formed on the end face of the second end of the body, and the connecting groove communicates with the threaded hole.

[0007] An anchor hole is also formed on the body, the anchor hole is connected to the threaded hole, the anchor hole is an arc-shaped hole, the inlet end is formed in the threaded hole, and the outlet end is formed on the side wall of the body.

[0008] A split bolt includes a connecting block and a bolt rod. The connecting block has a cylindrical structure and external threads formed on its side peripheral wall for connection with a threaded hole. A groove is formed on the end face of the first end of the connecting block, and a connecting piece is rotatably provided on the second end of the connecting block.

[0009] The first end of the bolt is fixedly mounted on the connecting piece, and the second end of the bolt forms a needle tip. The bolt is used to insert into the anchor hole, and the needle tip protrudes from the anchor hole.

[0010] Furthermore, a guide block is provided at the bottom of the threaded hole, and the guide block extends upward from the bottom of the threaded hole along the axis of the threaded hole to guide the bolt rod as it is inserted into the anchor hole.

[0011] Furthermore, the connecting piece is a circular piece, and the diameter of the connecting piece is less than or equal to the end face diameter of the connecting block. The connecting piece and the connecting block are connected by a rotating shaft.

[0012] The first end of the bolt is fixedly mounted on the connecting piece near the edge.

[0013] Furthermore, multiple bolts are provided, and the multiple bolts are evenly distributed along the circumference of the connecting piece.

[0014] Furthermore, the number of anchor holes is the same as the number of bolts, and they are evenly distributed around the guide block.

[0015] Furthermore, the main body of the thimble and the needle tip of the thimble are made of different materials; the main body of the thimble is made of a flexible material, while the needle tip is made of a metal material with a hardness greater than that of the main body.

[0016] Furthermore, the tip is conical, and the free end of the tip includes multiple blades, which are independent of each other, and the edges of the blades are formed with cutting edges.

[0017] Furthermore, the root of the blade is connected to the tip, and the tail of the blade forms the cutting edge, which has an arc-shaped structure.

[0018] Furthermore, the blades are evenly distributed in threes.

[0019] Furthermore, the dental implants suitable for immediate implantation and immediate restoration also include a stabilizer, which comprises a handle and a fixation segment, with an angle formed between the handle and the fixation segment.

[0020] The end of the fixed section forms a fixed block, which is used to be inserted into the connecting groove. The fixed section has a through hole that penetrates the fixed section and communicates with the threaded hole.

[0021] The beneficial effects of this invention are as follows:

[0022] The oral implants suitable for immediate implantation and immediate restoration provided by this invention can be connected and fixed by the sidewalls, tips and split plugs of the implant, thereby improving the reliability of the connection between the implant and the alveolar socket, improving the initial stability of the implant, and achieving the effect of immediate restoration.

[0032] The oral implants applicable to immediate implantation and restoration provided by this invention will be explained and described in detail below with reference to the accompanying drawings.

[0033] The oral implants suitable for immediate implantation and restoration provided by this invention utilize the implant's sidewalls, tip, and split plug to jointly connect and fix the implant, thereby improving the reliability of the implant's connection to the alveolar socket, enhancing the initial stability of the implant, and achieving the effect of immediate restoration. The invention will be described in detail below with reference to specific embodiments:

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown in one embodiment, the present invention provides an oral implant suitable for immediate implantation and immediate restoration, comprising an implant 1 and a split anchor 2. The implant 1 is connected to the alveolar socket via threads, and the split anchor 2 is disposed within the implant 1 and can be fixed to the sidewall of the alveolar socket by a pin tip, which can effectively prevent the implant 1 from loosening and improve the stability of the implant 1. In the accompanying drawings of this application, the internal and external threads formed on the implant 1 and the split anchor 2 are not shown in the figures.

[0035] like Figure 1 , Figure 2 As shown, in this embodiment, the implant 1 includes a body 11 and a tip 12. The body 11 is a cylindrical structure, and the tip 12 is located at the first end of the body 11. External threads are formed on the outer peripheral wall of the body 11, allowing the body 11 to be inserted into the alveolar socket by rotation and connected to the alveolar bone via the external threads. A threaded hole 111 extends axially from the second end of the body 11 towards the first end, and the threaded hole 111 is not connected to the first end of the body 11. A connecting groove 112 is formed on the end face of the second end of the body 11, communicating with the threaded hole 111. Optionally, the axes of the connecting groove 112 and the threaded hole 111 are collinear. Further, the connecting groove 112 can be a polygonal prism groove, meaning the inner wall of the connecting groove 112 is surrounded by multiple planes, allowing the implant 1 to be screwed into the alveolar bone with the help of a wrench.

[0036] An anchor hole 113 is also formed on the body 11, which communicates with the threaded hole 111. The anchor hole 113 is an arc-shaped hole, with its inlet end formed inside the threaded hole 111 and its outlet end formed on the side wall of the body 11. Optionally, the anchor hole 113 is located at the bottom of the threaded hole 111 from its inlet end and is inclined outward from the body 11, with the height of the outlet end lower than the height of the inlet end. Further, the anchor hole 113 is an arc-shaped hole and protrudes towards the side close to the axis of the body 11 to facilitate the installation of the split bolt 2 (described in detail below).

[0037] A guide block 114 is provided at the bottom of the threaded hole 111. The guide block 114 extends upward from the bottom of the threaded hole 111 along the axis of the threaded hole 111 and is used to guide the bolt 23 as it passes through the anchor hole 113. Optionally, the guide block 114 is a tapered structure formed at the bottom of the threaded hole 111, and its axis is collinear with the axis of the threaded hole 111. Further, the outer peripheral wall of the guide block 114 is a concave arc surface, for example, it can be tangent to the inner peripheral wall of the anchor hole 113, which can better play a guiding role.

[0038] The tip 12 is conical, and its free end includes multiple blades 13. These blades 13 are independent of each other, and each blade 13 has a cutting edge. In this embodiment, the root of each blade 13 is connected to the tip 12, and the tail of the blade 13 forms the cutting edge. The cutting edge has an arc-shaped structure, which increases its length and facilitates cutting into the bottom of the alveolar bone. Optionally, the blades 13 are shaped like propeller blades, allowing the cutting edge to extend along the direction of rotation, or the extension direction of the cutting edge can be approximately the same as the direction of rotation, so that the cutting edge can be screwed into the alveolar bone base as the body 11 rotates, tightly engaging with the alveolar bone. Furthermore, the tip of the cutting edge (i.e., the end that first contacts the alveolar bone during rotation) forms a pointed tip, making it easier to insert into the alveolar bone. In this embodiment, three blades 13 are evenly distributed, and the three blades 13 are independent of each other and can be screwed into the alveolar bone simultaneously. In other embodiments, two or five blades 13 can be used; the number of blades 13 is not limited here. The leaf 13 has a thin, sheet-like structure. When it is screwed into the alveolar bone, it can preserve the alveolar bone at the root to the greatest extent, which is conducive to the osseointegration of the implant 1. Moreover, it can be tightly integrated with the alveolar bone, thereby achieving good initial stability of the implant 1.

[0039] In this embodiment, as Figure 2 , Figure 3 As shown, the split bolt 2 includes a connecting block 21 and a bolt rod 23. The connecting block 21 is a cylindrical structure with external threads formed on its sidewall. The connecting block 21 is used for threaded connection with the threaded hole 111, and the length of the connecting block 21 is less than the length of the threaded hole 111. A groove 211 is formed on the end face of the first end of the connecting block 21, which is used to rotate the connecting block 21 with a screwdriver. A connecting piece 22 is rotatably provided on the second end of the connecting block 21. The connecting piece 22 is a circular piece, and its diameter is less than or equal to the end face diameter of the connecting block 21. The connecting piece 22 and the connecting block 21 are connected by a pivot, and the connecting piece 22 can rotate freely relative to the connecting block 21.

[0040] The first end of the stud 23 is fixedly positioned on the connecting piece 22 near its edge and can rotate synchronously with the connecting piece 22 relative to the connecting block 21. The second end of the stud 23 forms a needle tip, which is inserted into the anchor hole 113. The needle tip protrudes from the anchor hole 113 and pushes the stud 23 to move as the connecting block 21 rotates downward, causing the needle tip to insert into the alveolar bone, which can further stabilize the implant 1 in the alveolar socket.

[0041] Optionally, multiple studs 23 are provided, and the multiple studs 23 are evenly distributed along the circumference of the connecting piece 22. In this embodiment, three studs 23 are provided, and the three studs 23 are evenly distributed along the circumference of the connecting piece 22. The number of anchor holes 113 is the same as the number of studs 23, and they are evenly distributed around the guide block 114. Each stud 23 is inserted into an anchor hole 113 and is pushed as the connecting block 21 moves downward, causing the needle tip to pass through the anchor hole 113 and be inserted into the alveolar bone.

[0042] Optionally, the main body 231 and the needle tip 232 of the stud 23 are made of different materials. The main body 231 is made of a flexible material, while the needle tip 232 is made of a metal material with a hardness greater than that of the main body 231. For example, the main body 231 can be made of medical-grade silicone or other materials, which can bend under pressure and thus extend into the arc-shaped anchor hole 113. The needle tip 232 can be made of pure titanium for surgical implants that meets the 13810 standard, which has a certain degree of hardness and can be inserted into the alveolar bone under pressure.

[0043] like Figure 6 , Figure 7 As shown, the dental implants suitable for immediate implantation and immediate restoration also include a stabilizer 3, used to apply pressure to the implant 1 during the installation of the split plug 2, preventing the implant 1 from shaking. The stabilizer 3 includes a handle 32 and a fixing section 31, forming an angle between the handle 32 and the fixing section 31, optionally between 90 and 120 degrees. In this embodiment, the handle 32 and the fixing section 31 are perpendicular, forming a 90-degree angle. The end of the fixing section 31 forms a fixing block 311, which is used to insert into the connecting groove 112. The sidewall shape of the fixing block 311 is the same as the inner sidewall shape of the connecting groove 112, ensuring that the fixing block 311 can be smoothly inserted into the connecting groove 112. The fixing section 31 has a through hole 312, which penetrates the fixing section 31 and communicates with the threaded hole 111. When installing the split plug 2, a screwdriver can be inserted through the through hole 312 into the threaded hole 111 to rotate the connecting block 21. Optionally, the handle 32 is fitted with a non-slip sleeve for easy handholding by medical personnel. In this embodiment, the fixing block 311 and the connecting groove 112 are mutually cooperating polyhedral structures. For example, the fixing block 311 is a hexahedron, and the inner wall of the connecting groove 112 includes six planes. The two cooperate to complete the installation of the implant 1 through a stabilizer.

[0044] The oral implant for immediate implantation and restoration provided by this invention is used by first drilling a hole in the alveolar bone, and then screwing the implant body 11 into the drilled hole. After the implant body 11 is in place, the split plug 2 is inserted into the threaded hole 111, and then the fixing block 311 of the stabilizer 3 is inserted into the connecting groove 112. The medical staff applies pressure to the implant 1 by holding the handle 32 to prevent the implant 1 from shaking. Using a screwdriver, the connecting block 21 of the split plug 2 is rotated through the through hole 312 on the fixing section 31, so that the plug rod 23 enters the anchor hole 113 under the action of the guide block 114. Finally, the needle tip is inserted into the alveolar bone, thus completing the installation of the implant 1.

[0045] This invention relates to an oral implant suitable for immediate implantation and restoration. The implant 1 has blades 13 at its tip 12 on the body 11. After implantation, the blades 13 are arranged and screwed into the alveolar bone, maximizing the preservation of the alveolar bone at the root and facilitating osseointegration. This also ensures close integration with the alveolar bone, resulting in good initial stability. Furthermore, the design of a mid-section fastening pin further secures the implant 1 within the alveolar socket. This invention significantly reduces the technical difficulty of immediate implantation and restoration, offering high operability and expanding its clinical applicability.
