Description

Technical Field

[0001] The utility model relates to the technical field of dental implants, in particular to an anti - detachment dental implant. Background Art

[0002] Dental implants refer to a class of medical devices that are surgically implanted into the jawbone or placed on the jawbone to fix and support dentures, which can be gingiva - penetrating or completely buried under the gingiva;

[0003] After the existing implants are implanted, when people chew food, they will press down the implants through their teeth, and only rely on the threads on the surface of the implants to achieve the connection between the implants and the implant sockets. Over time, the implants will move downward continuously. In addition, the main stress part of the implant is at the root of the implant, which easily causes the implant sockets to become loose and atrophic, and then leads to the falling off of the installed teeth. Therefore, an anti - detachment dental implant is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art, and propose an anti - detachment dental implant.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti - detachment dental implant includes a base. A threaded installation groove is opened at the top end of the base. An implant post is threadedly arranged inside the threaded implantation groove. A plurality of strip - shaped grooves distributed circumferentially are opened on the inner wall of the base. An anti - loosening component is arranged inside the strip - shaped grooves. A hemispherical seat for relieving the root pressure is fixedly connected to the bottom end of the base.

[0007] Preferably, a fixing ring is fixedly connected to the side wall of the implant post, and a plurality of through holes are distributed circumferentially on the surface of the fixing ring.

[0008] Preferably, a plurality of threaded installation grooves distributed circumferentially are opened on the top end face of the base, and fixing bolts threadedly connected to the threaded installation grooves are arranged inside the through holes.

[0009] Preferably, a telescopic hole communicating with the strip - shaped groove is opened on the side wall of the base. The anti - loosening component includes a pushing plate slidably arranged inside the strip - shaped groove, and a pushing inclined surface is arranged at the top end of the pushing plate.

[0010] Preferably, a sliding column slidably connected to the telescopic hole is fixedly connected to one side surface of the pushing plate, and a limiting thorn is fixedly connected to one end of the sliding column.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. This solution is provided with an anti-loosening component. When the implant post enters the threaded installation groove, it will push the push plate around, thereby driving the sliding post and the limiting thorn to move, so that the limiting thorn penetrates into the inner wall of the planting groove, which can prevent the implant from rotating and avoid the implant from moving downward, providing the stability of the implant. The limiting thorn penetrates into the inner wall of the planting groove, plays a traction role on the inner wall of the planting groove, and plays a stabilizing role on the planting groove, making the planting groove not easy to collapse, thereby further improving the stability of the implant.

[0013] 2. This solution sets a hemispherical seat at the bottom end of the base. The hemispherical seat can increase the contact area between the bottom end of the base and the bottom end of the planting groove, play a role in relieving the pressure generated during chewing, and further relieve the atrophy degree of the planting groove caused by the pressure.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1-5, an anti-loosening dental implant, including a base 1. A threaded installation groove is opened at the top end of the base 1. An implant post 2 is threadedly arranged inside the threaded implantation groove. A plurality of strip-shaped grooves 102 distributed in a circumferential manner are opened on the inner wall of the base 1. An anti-loosening component is arranged inside the strip-shaped grooves 102. A telescopic hole 101 communicating with the strip-shaped grooves 102 is opened on the side wall of the base 1. The anti-loosening component includes a push plate 7 slidably arranged inside the strip-shaped grooves 102. A push inclined surface is arranged at the top end of the push plate 7. A sliding column 6 slidably connected with the telescopic hole 101 is fixedly connected to one side surface of the push plate 7. A limiting thorn 5 is fixedly connected to one end of the sliding column 6.

[0022] It should be noted that when the implant post 2 is screwed into the inside of the threaded installation groove, the implant post 2 will push against the inclined surface of the push plate 7, thereby realizing pushing the push plate 7 in all directions. The push plate 7 drives the limiting thorn 5 to move through the sliding column 6, so that the limiting thorn 5 pierces into the inner wall of the planting groove;

[0023] When the limiting thorn 5 pierces into the inner wall of the planting groove, it can prevent the implant from rotating, and at the same time can avoid the implant from moving downward, providing the stability of the implant. When the limiting thorn 5 pierces into the inner wall of the planting groove, it plays a traction role on the inner wall of the planting groove and plays a stabilizing role on the planting groove, making the planting groove not easy to collapse, thereby further improving the stability of the implant.

[0024] A hemispherical seat 4 for relieving the root pressure is fixedly connected to the bottom end of the base 1. The hemispherical seat 4 can increase the contact area between the bottom end of the base 1 and the bottom end of the planting groove, playing a role in relieving the pressure generated during chewing and further relieving the atrophy degree of the planting groove caused by the pressure.

[0025] A fixing ring 3 is fixedly connected to the side wall of the implant post 2. A plurality of through holes are distributed in a circumferential manner on the surface of the fixing ring 3. A plurality of threaded installation grooves distributed in a circumferential manner are opened on the top end face of the base 1. Fixing bolts threadedly connected with the threaded installation grooves are arranged inside the through holes.

[0026] It should be noted that by connecting the fixing bolts with the threaded installation grooves, the rotation of the implant post 2 can be avoided.

[0027] When the present utility model is in use, first implant the base 1 into the inside of the planting groove, and then screw the implant post 2 into the inside of the threaded implantation groove. During the downward movement of the implant post 2, it will push against the inclined surface of the push plate 7, thereby realizing pushing the push plate 7 in all directions. The push plate 7 drives the limiting thorn 5 to move through the sliding column 6, so that the limiting thorn 5 pierces into the inner wall of the planting groove. When the limiting thorn 5 pierces into the inner wall of the planting groove, it can prevent the implant from rotating, and at the same time can avoid the implant from moving downward, providing the stability of the implant. When the limiting thorn 5 pierces into the inner wall of the planting groove, it plays a traction role on the inner wall of the planting groove and plays a stabilizing role on the planting groove, making the planting groove not easy to collapse, thereby further improving the stability of the implant;

[0028] The hemispherical seat 4 at the bottom end of the implant can increase the contact area between the base 1 and the bottom of the planting groove, thereby reducing the extrusion force of the base 1 on the planting groove and reducing the degree of atrophy of the planting groove caused by the pressure.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
