DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 , an implant abutment that is easy to fix in the illustration, including an abutment body 101 and an implant 102, and further including a fixing component arranged on the abutment body 101 for fixing with the implant 102;

[0022] The fixing component includes a mounting frame 201 fixedly connected to one side of the abutment body 101 close to the implant 102. Two opposite side walls of the mounting frame 201 are slidably connected with fixing plates 202. The mounting frame 201 is provided with a pressing component for pressing the two fixing plates 202. An installation hole 203 is opened on one side of the implant 102 close to the abutment body 101, and two fixing holes 204 are opened on the inner wall of the installation hole 203. The two fixing holes 204 are arranged to match the fixing plates 202;

[0023] It should be noted here that: through the setting of the fixing component, under the action of the pressing component, while ensuring the connection stability and safety between the abutment body 101 and the implant 102, the fixing convenience between the abutment body 101 and the implant 102 is improved, and under the action of the driving component and the pushing component, it is convenient to disassemble the connection between the abutment body 101 and the implant 102 in the future.

[0024] It is worth noting that: the connection method between the abutment body 101 and the dental crown is the same as that of the implant 102, and will not be elaborated here.

[0025] Please refer to Figure 3 , on one side of the two fixing plates 202 close to the implant 102, a first inclined surface 205 is opened;

[0026] It should be noted here that: through the setting of the first inclined surface 205, when the fixing plate 202 abuts against the side wall of the installation hole 203, under the mutual acting force of the first inclined surface 205 and the guiding action of the pressing component, the two fixing plates 202 will be pushed to contract into the mounting frame 201.

[0027] Please refer to Figure 4, in the illustrated figure, the extrusion assembly includes an extrusion tube 301 fixedly connected to the inner wall of the mounting frame 201 away from the base body 101. An extrusion rod 304 is slidably connected to the extrusion tube 301. One end of the extrusion rod 304 close to the base body 101 is fixedly connected to an extrusion plate 303. The extrusion plate 303 is provided with a driving assembly for driving the two fixing plates 202. The other end of the extrusion rod 304 away from the extrusion plate 303 is located inside the extrusion tube 301 and is fixedly connected to an extrusion circular plate 305. A spring 306 is sleeved on the inner side wall of the extrusion rod 304 inside the extrusion tube 301. Two ends of the spring 306 are respectively connected to the extrusion circular plate 305 and the inner wall of the extrusion tube 301;

[0028] It should be noted here that: through the setting of the extrusion assembly, while providing guidance and reset functions for the movement of the two fixing plates 202, the two fixing plates 202 maintain a constant extrusion force on the implant 102 under the elastic extrusion action of the extrusion assembly.

[0029] Please refer to Figure 4 , in the illustrated figure, the driving assembly includes two rotating plates 401 rotatably connected to the side of the extrusion plate 303 close to the extrusion tube 301. The other ends of the two rotating plates 401 are rotatably connected to the fixing plate 202. A driving plate 402 is fixedly connected to the side of the extrusion plate 303 close to the base body 101. The base body 101 is provided with a pushing assembly for pushing the driving plate 402;

[0030] It should be noted here that: through the setting of the driving assembly, it is convenient to drive the two fixing plates 202 to move closer to each other.

[0031] Working principle: When connecting the base body 101 and the implant 102, first align the mounting frame 201 of the base body 101 with the mounting hole 203 on the implant 102, and then push the base body 101 to move closer to the implant 102, so that the mounting frame 201 is inserted into the mounting hole 203. During the sliding process of the mounting frame 201 in the mounting hole 203, when the fixing plate 202 abuts against the side wall of the mounting hole 203, under the mutual acting force of the first inclined surface 205 and the guiding action of the extrusion assembly, the two fixing plates 202 will be pushed to contract into the mounting frame 201;

[0032] When the abutment body 101 is continuously pushed closer to the implant 102, when the end face of the abutment body 101 abuts against the end face of the implant 102, the two fixing plates 202 will be aligned with the fixing holes 204. At this time, under the elastic action of the pressing assembly, the two fixing plates 202 will be pushed into the fixing holes 204 and abut against the bottom wall of the fixing holes 204. Thus, through the abutting action of the two fixing plates 202, the connection and fixation between the abutment body 101 and the implant 102 are realized. Moreover, under the elastic pressing action of the pressing assembly, the two fixing plates 202 maintain a constant pressing force on the implant 102. Therefore, while ensuring the connection stability and safety between the abutment body 101 and the implant 102, the fixing convenience between the abutment body 101 and the implant 102 is improved. And under the action of the driving assembly and the pushing assembly, it is convenient to disassemble the connection between the abutment body 101 and the implant 102 in the future.

[0033] Embodiment 2

[0034] Please refer to Figure 3 and Figure 4 This embodiment further illustrates Embodiment 1. The pushing assembly shown in the figure includes a pushing cavity 501 opened in the abutment body 101. The inner wall of the pushing cavity 501 is threadedly connected with a threaded rod 502. The side of the driving plate 402 away from the pressing plate 303 is located inside the pushing cavity 501 and is provided with a second inclined surface 503. The end of the threaded rod 502 away from the driving plate 402 penetrates through the abutment body 101 and is provided with a rotation hole 504 arranged in a regular hexagon.

[0035] It should be noted here that when it is necessary to release the fixed connection between the abutment body 101 and the implant 102, the threaded rod 502 is rotated by an inner hexagon wrench. Under the action of threaded meshing transmission, one end of the threaded rod 502 approaches the driving plate 402. When one end of the threaded rod 502 abuts against the second inclined surface 503 on the driving plate 402, under the interaction force and the guiding action of the pressing assembly, the driving plate 402 will be pushed to move away from the mounting frame 201, thereby further driving the pressing plate 303 to move synchronously. During the movement of the pressing plate 303, the rotating plate 401 will be driven to rotate, thereby further driving the two fixing plates 202 to contract into the mounting frame 201.

[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
