Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental implant technology, and more specifically, to a titanium-free base fixation device for preventing loosening of dental implants. Background Technology
[0002] With the development of oral medicine, dental implant technology has become increasingly sophisticated. A dental implant generally consists of an implant body, an abutment, and a crown. During implantation, the implant is first fixed into the alveolar bone. After it has integrated tightly with the jawbone, the abutment is installed, and finally, the crown is attached to the abutment. Once the implant has integrated firmly with the alveolar bone, the implanted tooth can withstand the chewing forces just like a natural tooth. The connection between the implant and the abutment must be secure; otherwise, the implantation outcome will be affected.
[0003] However, in some existing titanium-free dental implant fixation devices, the implant root and abutment are usually connected by a threaded bolt. However, with only a threaded connection structure, the screw is prone to slight vibration during chewing due to the repeated and continuous load applied in the oral cavity. The amplitude of the vibration gradually increases, which can easily cause rotation and loosening of the thread. This results in a gap between the implant root and the abutment, causing the abutment to wobble and affecting the patient's normal chewing. In actual use, the stability and practicality are poor. In view of this, we propose a titanium-free dental implant fixation device to solve the above problems. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0030] Example 1
[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A non-titanium-based fixation device for preventing loosening of dental implants includes an implant root 1, a slot 2 inside the implant root 1, an abutment 3 inside the slot 2, a threaded protrusion 5 on the inner wall of the slot 2, a threaded groove 6 on the surface of the abutment 3, the abutment 3 being threadedly connected to the inside of the slot 2 through the engagement of the threaded groove 6 and the threaded protrusion 5, an annular groove 4 on the bottom surface of the slot 2, a groove 7 on the bottom surface of the abutment 3, an elastic piece 8 fixedly connected inside the groove 7, the elastic piece 8 being inclined, a first cavity 9 inside the abutment 3, and a connecting component inside the first cavity 9.
[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the surface of the dental implant root 1 is provided with implantation threads 20. The implantation threads 20 are provided so that the dental implant root 1 can be screwed into the alveolar bone.
[0033] Example 2
[0034] The titanium-free dental implant fixation device for preventing loosening provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the connecting assembly includes a pull rope 10, which is located inside the first cavity 9. Both ends of the pull rope 10 slide through the interior of the foundation pile 3, and both ends of the pull rope 10 slide into the grooves 7 on both sides respectively.
[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the two ends of the pull rope 10 are fixedly connected to two elastic plates 8 respectively. By moving the two ends of the pull rope 10, the two elastic plates 8 can be pulled towards the middle. Subsequently, the pull rope 10 can be reset by the elastic force of the elastic plates 8 themselves.
[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a pressure rod 11 is provided inside the first cavity 9. The upper end of the pressure rod 11 slides through the interior of the foundation pile 3. An embedding groove 12 is provided on the lower surface of the pressure rod 11. The embedding groove 12 is adapted to the pull rope 10. The pull rope 10 is embedded into the interior of the embedding groove 12 by moving the pressure rod 11 downward. At this time, the two ends of the pull rope 10 will move towards the middle, thereby pulling the two elastic pieces 8 into the interior of the groove 7 until the elastic pieces 8 are taken into the interior of the groove 7.
[0037] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a second cavity 13 is provided inside the foundation pile 3. The upper end of the pressure rod 11 slides through the interior of the second cavity 13. A circular plate 14 is fixedly connected to one end of the pressure rod 11 inside the second cavity 13. The circular plate 14 is slidably connected inside the second cavity 13. The circular plate 14 can be driven to slide inside the second cavity 13 by moving the pressure rod 11.
[0038] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a compression spring 15 is fixedly connected between the lower surface of the circular plate 14 and the bottom wall of the second cavity 13. The compression spring 15 is movably sleeved on the outside of the pressure rod 11. When the circular plate 14 moves with the pressure rod 11, the compression spring 15 will undergo elastic deformation. Subsequently, the circular plate 14 can be reset by the elastic force of the compression spring 15 itself, which in turn drives the pressure rod 11 to reset.
[0039] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a sliding groove 16 is provided at the top of the foundation pile 3, and a rectangular rod 17 is fixedly connected to the upper surface of the circular plate 14. The upper end of the rectangular rod 17 slides through the interior of the sliding groove 16, and a driving block 18 is fixedly connected to the upper end of the rectangular rod 17. A driving groove 19 is provided on the upper surface of the driving block 18.
[0040] The process of using the titanium-free base fixation device for preventing loosening of dental implants provided by this utility model is as follows:
[0041] When the staff needs to remove the abutment 3 from the inside of the implant root 1, they use an external tool inserted into the drive groove 19 and then press down on the drive block 18. At this time, the drive block 18 will slide inside the sliding groove 16. The drive block 18 will drive the rectangular rod 17 to move downward. The movement of the rectangular rod 17 will drive the circular plate 14 to move. At this time, the circular plate 14 will drive the pressure rod 11 to move downward, and the compressed spring 15 will produce elastic deformation. Subsequently, the downward movement of the pressure rod 11 will cause the pull rope 10 to be embedded in the insertion groove 12. At this time, the two ends of the pull rope 10 will move towards the middle, thereby pulling the two elastic pieces 8 into the groove 7 until the elastic pieces 8 are retracted into the groove 7. Then, the staff uses an external tool to rotate the drive block 18. The rotation of the drive block 18 will drive the rotation of the rectangular rod 17, which will drive the abutment 3 to rotate. At this time, because the threaded protrusion 5 and the threaded groove 6 are threadedly connected, and the elastic pieces 8 are located inside the groove 7, the abutment 3 and the implant root 1 can be removed.
[0042] If the pressing drive block 18 is not operated, the screw will rotate due to the threaded engagement between the threaded protrusion 5 and the threaded groove 6. However, the upper end of the elastic plate 8 and the top wall of the annular groove 4 will abut against each other, so the screw cannot move. This effectively prevents the screw from becoming loose. Only by pressing and rotating simultaneously can the screw move.
