Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis technology, and in particular to an implant device for fixed dentures. Background Technology

[0002] Dental implants involve inserting an implant (artificial tooth root) into the alveolar bone in the edentulous area of ​​the mouth. After the implant has taken, a prosthesis is fabricated on top of it to complete the restoration. It can significantly improve the patient's chewing function and feels comfortable, similar to natural teeth. Many difficult clinical cases that are difficult to resolve with conventional dentures can achieve satisfactory results with dental implants. Fixed dentures are prostheses that restore one or more missing teeth in the dentition. They are connected to the prepared abutment teeth or implants on both sides of the missing tooth by adhesives or fixation devices, thereby restoring the anatomical shape and physiological function of the missing tooth. Because patients cannot remove or wear these prostheses themselves, they are simply called fixed dentures.

[0003] Currently, CN222237870U discloses an implant device for fixed dentures, including a denture, a connector, an implant post, and a retaining ring. The connector consists of an insert section and a retaining section connected vertically. The bottom of the insert section has an internal threaded hole for threaded connection of the implant post, and the top of the retaining section has a countersunk hole. A retaining ring is fitted onto the outer side of the retaining section. The bottom of the denture has a retaining groove and an insert groove connected vertically. The insert section is slidably inserted into the insert groove, and the retaining ring is engaged in the retaining groove. After freezing, the retaining ring can be fitted onto the outer side of the retaining section, allowing the denture to be smoothly fitted onto the outer side of the connector. After the retaining ring returns to room temperature, it moves downwards towards the connector, causing the denture to move downwards, thereby effectively reducing the gap between the denture and the gum. After drilling a hole in the denture above the connector, the connector can be unscrewed, and the denture can be easily removed.

[0004] However, although the above-mentioned solution allows for the assembly and disassembly of the denture via connectors, it can cause great inconvenience to the user during actual operation due to the limited space inside the oral cavity. Therefore, we provide an implant device for fixed dentures. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an implant device for fixed dentures, which solves the technical problem that, although the dentures can be disassembled and assembled using connectors, the limited space inside the oral cavity causes great inconvenience to the user during actual operation.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: An implant device for a fixed denture includes a denture with a rectangular groove at the bottom, a rectangular post inside the rectangular groove, a positioning element inside the rectangular post, an implant pin below the rectangular post, and a threaded post fixedly connected to the top of the implant pin.

[0007] Preferably, the rectangular column has a threaded groove at its lower part for connecting with the threaded column.

[0008] Preferably, the size of the rectangular column corresponds to the size of the rectangular groove.

[0009] Preferably, the positioning element includes two positioning rods symmetrically arranged inside the rectangular column, a restoring spring is provided on the outside of the positioning rod, and a limiting piece is fixedly sleeved on the outside of the positioning rod.

[0010] Preferably, the two ends of the restoring spring are fixedly connected to the limiting plate and the inner wall of the rectangular column, respectively.

[0011] Preferably, a compression rod is slidably embedded in the upper part of the rectangular column, and a conical block is fixedly connected below the compression rod. The surface of the conical block has two positioning holes corresponding to the positioning rod.

[0012] Preferably, the center of the threaded groove and the center of the threaded post are located on the same horizontal line.

[0013] (III) Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a positioning component to fit the rectangular groove at the bottom of the denture onto the outside of a rectangular post. During the downward fitting process, the inner wall of the denture pushes the compression rod downward. As the compression rod moves downward, it causes the conical block to press against the positioning rods on both sides. The limiting plate outside the positioning rod compresses the restoring spring, causing the entire denture to move downward until one end of the positioning rod enters the locking holes on both sides of the denture, thus fixing the denture in place. The other end of the positioning rod then enters the positioning hole, effectively fixing the position of the positioning rod and preventing the conical block from moving up and down, thereby enhancing the fixation effect on the denture.

[0016] This application provides an implant device for fixing dentures. The rectangular groove at the bottom of the denture is fitted onto the outside of a rectangular post. During the downward fitting process, the inner wall of the denture pushes the compression rod downward. As the compression rod moves downward, the conical block compresses the positioning rods on both sides. The limiting plate outside the positioning rod compresses the restoring spring. At this time, the entire denture moves downward until one end of the positioning rod enters the locking holes on both sides of the denture, thus fixing the denture. The other end of the positioning rod enters the positioning hole, which can effectively fix the position of the positioning rod and prevent the conical block from moving up and down, thereby enhancing the fixing effect of the denture.

[0017] Example 1 The technical solution in this application embodiment effectively solves the technical problem that, although the above-mentioned solution allows for the assembly and disassembly of the denture via connectors, the limited space inside the oral cavity causes great inconvenience to the user during actual operation. The overall idea is as follows: like Figures 1 to 4 To address the problems existing in the prior art, this utility model provides an implant device for fixed dentures, including a denture 1. A rectangular groove 42 is provided at the bottom of the denture 1. A rectangular post 4 is provided inside the rectangular groove 42. A positioning element 43 is provided inside the rectangular post 4. An implant pin 2 is provided below the rectangular post 4. A threaded post 3 is fixedly connected to the top of the implant pin 2. A threaded groove 41 is provided below the rectangular post 4 for connecting with the threaded post 3. The size of the rectangular post 4 corresponds to the size of the rectangular groove 42. The center of the threaded groove 41 and the center of the threaded post 3 are located on the same horizontal line.

[0018] By adopting the above technical solution, when installing the denture 1, the implant 2 is first connected to the patient using a special tool, and then the threaded post 3 is threadedly connected to the threaded groove 41 below the rectangular post 4. After installation, the rectangular groove 42 at the bottom of the denture 1 is fitted onto the outside of the rectangular post 4.

[0019] Specifically, the positioning component 43 includes two positioning rods 431 symmetrically arranged inside the rectangular column 4. A restoring spring 433 is provided on the outside of the positioning rods 431. A limiting piece 432 is fixedly sleeved on the outside of the positioning rods 431. The two ends of the restoring spring 433 are fixedly connected to the limiting piece 432 and the inner wall of the rectangular column 4, respectively. A pressing rod 434 is slidably embedded in the upper part of the inside of the rectangular column 4. A conical block 435 is fixedly connected below the pressing rod 434. Two positioning holes 436 corresponding to the positioning rods 431 are opened on the surface of the conical block 435.

[0020] By adopting the above technical solution, the rectangular groove 42 at the bottom of the denture 1 is fitted onto the outside of the rectangular post 4. During the downward fitting process, the inner wall of the denture 1 pushes the compression rod 434 downward. As the compression rod 434 moves downward, the conical block 435 presses against the positioning rods 431 on both sides. The limiting piece 432 outside the positioning rod 431 compresses the restoring spring 433. At this time, the denture 1 moves downward as a whole until one end of the positioning rod 431 enters the locking holes on both sides of the denture 1, thus completing the fixation of the denture 1. The other end of the positioning rod 431 enters the positioning hole 436, which can effectively fix the position of the positioning rod 431 and prevent the conical block 435 from moving up and down, thereby enhancing the fixation effect of the denture 1.

[0021] Working principle: During use, when installing denture 1, the implant 2 is first connected to the patient using a special tool. Then, the threaded post 3 is threaded into the threaded groove 41 below the rectangular post 4. After installation, the rectangular groove 42 at the bottom of denture 1 is fitted onto the outside of the rectangular post 4. During the downward fitting process, the inner wall of denture 1 pushes the compression rod 434 downward. As the compression rod 434 moves downward, the conical block 435 compresses the positioning rods 431 on both sides. The limiting piece 432 outside the positioning rod 431 compresses the restoring spring 433. At this time, denture 1 moves downward as a whole until one end of the positioning rod 431 enters the locking holes on both sides of denture 1, thus completing the fixation of denture 1. The other end of the positioning rod 431 enters the positioning hole 436, which can effectively fix the position of the positioning rod 431 and prevent the conical block 435 from moving up and down, thereby enhancing the fixation effect of denture 1.

[0022] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
