Description

Technical Field

[0001] The utility model relates to the field of short implants, in particular to a short dental implant with a locking mechanism. Background Art

[0002] Dental implants are a surgical procedure that inserts artificial tooth roots, also called short implants, into the jawbone to replace missing teeth. Dentures are then placed on the artificial roots to restore the function and aesthetics of the missing teeth.

[0003] Short implants are usually made of columnar titanium metal material, and the outside of the columnar short implant has side protrusions to improve the stability of the short implant implanted in the jawbone. However, in order to reduce the damage caused by the short implant to the tissues and nerves inside the jawbone, the length of the short implant is designed to be shorter.

[0004] Since the short implant is short, and a denture is installed on the short implant, and the denture is subjected to force, the denture and the short implant may be separated from the jawbone. In addition, when the short implant is implanted, a vertical hole is opened on the jawbone, and then the short implant is fixed with a thread. Fixing bumps directly on both sides of the short implant increases the stability of the short implant installation, which will affect the installation of the short implant and thus have certain defects.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The utility model provides Figure 1-3 The short dental implant with a locking mechanism shown in the figure includes a short implant 1, a locking assembly 2 is provided inside the short implant 1, the locking assembly 2 includes a locking block 21, a connecting assembly 24 and an adjusting assembly 25, a mounting groove 22 is provided on the top of the short implant 1, a mounting hole 23 matching the locking block 21 is provided at the bottom of the inner wall of the mounting groove 22, and a threaded groove matching the short implant 1 is provided on one side of the locking block 21. When the short implant 1 is installed in the vertical hole groove opened on the jaw, the locking blocks 21 on both sides of the short implant 1 are in a vertical storage state, so that the short implant 1 and the locking block 21 can be spirally rotated and installed in the vertical hole groove opened on the jaw The connecting component 24 is arranged at the bottom of the inner cavity of the installation groove 22, and the locking block 21 is rotatably connected to the short implant 1 through the connecting component 24. The adjusting component 25 is arranged inside the installation groove 22. The adjusting component 25 is used to drive the locking block 21 to rotate and protrude. When the short implant 1 is installed, the adjusting component 25 drives the locking block 21 to rotate through the connecting component 24, so that the locking blocks 21 on both sides of the short implant 1 can be rotated and protruded, thereby increasing the cross-street area of ​​the short implant 1 inside the jaw, and the inclined locking block 21 can limit the short implant 1 to ensure the stability of the installation of the short implant 1, so as to facilitate the later installation of the fixing seat and denture on the short implant 1.

[0032] The locking plate 21 is fixed to the support 241 by the support 242, and the locking plate 21 is fixed to the support 241 by the support 242.

[0033] Furthermore, the connecting assembly 24 also includes an elastic member 245, a fixing screw 246 and an inner screw 247. The elastic member 245 is fixedly connected to the side of the support block 241 away from the locking block 21 by the fixing screw 246. The elastic member 245 can provide a supporting force to the fixing plate 242, so that when the short implant 1 is installed, the locking block 21 is in a stable storage state, thereby preventing the locking block 21 from protruding and affecting the installation of the short implant 1 when the short implant 1 is installed. The bottom of the inner wall of the installation groove 22 is symmetrically provided with a groove matching the support block 241. The support block 241 is fixedly connected to the short implant 1 by the inner screw 247, and the inner screw 247 is installed from the bottom of the short implant 1, thereby ensuring the stability of the installation of the support block 241.

[0034] The screw threaded rod 251 is screwed into the groove 22, and the hemisphere 252 is fixedly connected to the bottom of the screw threaded rod 251. The inner wall of the groove 22 is provided with an internal thread matching the screw threaded rod 251. The top of the screw threaded rod 251 is provided with a rectangular groove 253. The hemisphere 252 is located at the top of the fixing plate 242. After the short implant 1 is installed, a rectangular rod-shaped object is used to dock with the rectangular groove 253, and the screw threaded rod 251 is rotated so that the hemisphere 252 at the bottom of the screw threaded rod 251 squeezes the fixing plate 242 away from one end of the locking block 21. The fixing plate 242 can drive the locking block 21 to rotate around the shaft 243, so that the locking block 21 part protrudes relative to the short implant 1, and then the locking block 21 protrudes and is engaged in the jawbone, thereby improving the stability of the installation of the short implant 1.

[0035] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
