Description

Technical Field

[0001] The utility model relates to the technical field of denture implantation, in particular to a composite implantation denture component. Background Art

[0002] Denture implants are also known as denture implants. Denture implants are implants placed in the alveolar bone in the edentulous area of ​​the mouth. After the implant takes hold, a restoration is made on its upper end to complete the restoration of the implant denture. It can significantly improve the patient's chewing function and feel comfortable like real teeth. Denture implants are basically dentures fixed to dental implants. Denture implants also help protect the jawbone. When you are missing a tooth, the jawbone in this area tends to atrophy because there is nothing to hold it, which may affect your bite. Implanted dentures replace the missing tooth roots and fuse the jawbone, which will help your jaw remain unchanged.

[0003] After searching, the applicant found that a Chinese patent disclosed "an implant for improving the comfort of denture implantation", and its publication (announcement) number is "CN217593101U". This patent mainly reduces the upper and lower vibrations of the denture body by setting a first spring, and reduces the left and right vibrations of the denture body to a certain extent through the cooperation of the limit ring, the annular groove and the buffer pad. However, the second threaded rod of the device is prone to slight displacement or rotation due to external forces (such as chewing force, friction, etc.) during long-term use. This continuous small movement will lead to increased friction between the threads and increased wear, which in turn affects the matching accuracy of the threaded rod and the base. For this reason, we propose a composite implant denture component. Utility Model Content

[0004] The purpose of the present utility model is to provide a composite implant denture component to solve the problem proposed in the above-mentioned background technology that the second threaded rod of the device is prone to slight displacement or rotation due to external forces (such as chewing force, friction, etc.) during long-term use. This continuous small movement will lead to increased friction between the threads and increased wear, thereby affecting the matching accuracy of the threaded rod and the base.

The mounting structure 1 is connected to the implant structure 3 through the connecting structure 2. The mounting structure 1 includes a denture 11. The interior of the denture 11 is respectively provided with a first thread groove 12 and a second thread groove 13. The first thread groove 12 and the second thread groove 13 are connected to each other, and the diameter of the second thread groove 13 is smaller than that of the first thread groove 12. A control groove 14 is provided at the end of the denture 11 and at the position where it is connected to the second thread groove 13. A sealing cover 15 can be detachably installed on the control groove 14.

[0023] The connecting structure 2 includes a base 21, a first threaded rod 22 and a second threaded rod 23. The first threaded rod 22 and the second threaded rod 23 are respectively fixedly installed on the top and bottom ends of the base 21. The second threaded rod 23 is threadedly connected to the first thread groove 12. A limiting groove 24 is provided at the middle position of the top end of the first threaded rod 22. A limiting ring groove 25 is provided on the top side wall of the first threaded rod 22 and at the bottom of the limiting groove 24. A limiting hole 26 is provided at the middle position of the bottom end of the second threaded rod 23. A limiting screw 27 is threadedly installed inside the denture 11 and in the second thread groove 13. A turntable is fixedly installed at one end of the limiting screw 27. The turntable is inside the control groove 14, and the end of the limiting screw 27 cooperates with the limiting hole 26.

[0024] Specifically, in the connection structure 2, the limiting screw 27 extends into the second threaded rod 23 for limiting. The two screws interact with each other to balance the force on the denture 11, reduce the possibility of loosening, and improve stability. The limiting screw 27 provides additional fixing torque to effectively prevent the denture 11 from rotating or displacing. It can also position the second threaded rod 23 so that the denture 11 is in close contact with the base 21, ensuring comfort and functionality, and ensuring the good performance of the denture 11 during use.

[0025] Example 2:

[0026] Please see the attached Figure 2 and attached Figure 5The cam 33 is connected to the first screw rod 22 by the internal thread, and the cam 33 is connected to the first screw rod 22 by the internal thread. The top of the cam 33 is fixedly installed with a limit rod 32 and a first spring 33. The first spring 33 is sleeved on the limit rod 32, and one end of the first spring 33 is a free end. A slide groove is provided on the side wall of the cam 33, and the limit cylinder 34 is symmetrically fixed on the outer wall of the cam 31. The limit cylinder 34 is aligned with the slide groove. The inner wall of the cam 31 and the fixing plate 36 are fixedly installed on one side of the limit cylinder 34. A slide rod 35 is slidably installed in the fixing plate 36. The end of the slide rod 35 cooperates with the limiting ring groove 25. The slide rod 35 is fixedly installed on the side away from the fixing plate 36. The slide plate 37 is slidably connected to the slide groove of the implant 31. A second spring 38 is sleeved on the slide rod 35. One end of the second spring 38 is fixedly connected to the fixing plate 36, and the other end of the second spring 38 is fixedly connected to the slide plate 37.

[0027] Specifically, in the planting structure 3, when the first threaded rod 22 moves, the slide rod 35 automatically extends into the limiting ring groove 25 under the elastic force of the second spring 38 to limit it. This can prevent the first threaded rod 22 from excessive rotation or movement during installation, ensure that the installation position is accurate and stable, and will not be excessively displaced or shaken during use, reduce unnecessary friction and wear between threads, prevent loosening, and thus extend the service life of the threaded connection.

[0028] The working principle of the utility model is a composite implant denture component. First, the implant body 31 is implanted in the tooth root for fixation, and then the first threaded rod 22 is extended into the implant body 31. The rotating base 21 drives the first threaded rod 22 to rotate in the implant body 31, so that the first threaded rod 22 moves in the implant body 31. When the first threaded rod 22 moves, the side wall of the first threaded rod 22 presses the slide rod 35, and the slide rod 35 drives the slide plate 37 to slide in the slide groove, so that the slide rod 35 moves toward the direction of the limiting cylinder 34. At the same time, the slide plate 37 compresses the second spring 38. When the first threaded rod 22 continues to move, the limiting rod 32 will extend into the limiting groove 24 and compress the first spring 33. Wait until the limiting ring groove 2 When the slide rod 35 is aligned with the slide groove in the implant 31, the slide rod 35 automatically resets under the elastic force of the second spring 38, so that the end of the slide rod 35 extends into the limiting ring groove 25, and the first threaded rod 22 is limited by the slide rod 35, making the first threaded rod 22 more stable, and the first threaded groove 12 on the denture 11 is aligned with the second threaded rod 23, thereby fixing the denture 11 and the second threaded rod 23. The turntable is rotated to drive the limiting screw 27 to rotate, and the limiting screw 27 moves inside the denture 11, so that the end of the limiting screw 27 extends into the limiting hole 26, thereby limiting the second threaded rod 23. Finally, the sealing cover 15 is fixedly installed on the control groove 14 to seal the control groove 14.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
