Technical Field

[0001] The utility model relates to the technical field of implant abutments, in particular to a novel implant abutment for dental implantation. Background Art

[0002] In dental implantation surgery, an implant abutment is required to connect an artificial dental crown and an implant. As a key connecting component, the implant abutment can better adapt to the patient's oral condition, improve the accuracy and stability of dental implants, thereby reducing the discomfort of the patient during the implantation surgery, and helping to improve the fusion of the implant with the surrounding bone tissue.

[0003] After retrieval, Chinese Patent Publication No.: CN211381883U discloses a novel implant abutment for dental implantation, including an abutment body. A abutment screw is arranged inside the abutment body. The lower end of the abutment screw is connected to an implant. The upper part of the abutment body is connected to a dental crown. A crown screw is arranged inside the dental crown. The crown screw is connected to the abutment body. The outside of the abutment body and the dental crown is provided with gingiva. The crown screw is inclined, with one end connected to the dental crown and the other end connected to the abutment body.

[0004] In the above technology, the inclined way is adopted to connect one end of the crown screw to the dental crown and the other end to the abutment body, which can avoid the material on the hole of the later plugging from falling off, and improve the tightness and stability of the connection between the dental crown and the abutment body. However, with the long-term use of the dental crown, wear will occur, and the dental crown needs to be disassembled and replaced. It is necessary to disassemble the two inclined screws. During the disassembly and installation process, it is easy to cause a gap between the threaded hole and the screw, and the disassembly and installation process is also more cumbersome, which is likely to affect the subsequent use effect and replacement efficiency of the dental crown. Therefore, a novel implant abutment for dental implantation is proposed to solve the above problems. Summary of the Invention

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Referring to Figure 1-3 , an embodiment provided by the present invention: a new type of implant abutment for dental implant, including an implant body 1, the top of the implant body 1 is fixedly connected with an abutment body 2, the top of the abutment body 2 is provided with a mounting seat 4, the top of the mounting seat 4 is fixedly connected with a dental crown 3, the middle of the abutment body 2 is slidably connected with an abutment screw 6, the abutment screw 6 penetrates through the abutment body 2 and is threadedly connected to the middle of the implant body 1, the bottom of the abutment body 2 is fixedly connected with a positioning block 15, and a positioning groove 17 is opened in the middle of the implant body 1, and the positioning block 15 is slidably connected to the middle of the positioning groove 17.

[0028] During use, first, the implant body 1 and the abutment body 2 can be quickly positioned through the positioning block 15 and the positioning groove 17, so that the two abutment screws 6 sliding in the abutment body 2 can be quickly aligned with the threaded holes on the implant body 1 for installation, thereby improving the installation efficiency and stability of the abutment body 2, so that the dental crown 3 can be installed on the abutment body 2.

[0029] Referring to Figure 1 、 3 and 4, the bottom of the mounting seat 4 is fixedly connected with an insertion block 18, the insertion block 18 is slidably connected to the middle of the abutment body 2, a slot 9 is opened in the middle of the abutment body 2, the insertion block 18 is slidably connected to the middle of the slot 9, a bidirectional threaded rod 12 is rotatably connected to the middle of the abutment body 2, the outer circumference of the bidirectional threaded rod 12 is threadedly connected with a threaded block 13, the top of the threaded block 13 is fixedly connected with a movable block 10, the other end of the movable block 10 is slidably connected to the middle of the insertion block 18, a through groove is provided in the middle of the insertion block 18, the movable block 10 is slidably connected to the middle of the through groove, and an arc edge is provided at one end of the movable block 10 away from the threaded block 13.

[0030] During use, insert the insertion block 18 at the bottom of the mounting base 4 into the middle of the abutment body 2 through the slot 9, then rotate the bidirectional threaded rod 12 to drive the threaded block 13 to move, so that the threaded block 13 drives the two movable blocks 10 to insert into the middle of the insertion block 18. At the same time, under the action of the arc edge, the movable block 10 can pull the insertion block 18 downward, so that the dental crown 3 can be tightly connected to the abutment body 2 through the insertion block 18 at the bottom of the mounting base 4. Similarly, rotating the bidirectional threaded rod 12 in the reverse direction can make the two threaded blocks 13 move towards each other, so that the movable block 10 can be withdrawn from the middle of the insertion block 18, so that the dental crown 3 can be removed from the top of the abutment body 2, thereby improving the convenience of installing and disassembling the dental crown 3. At the same time, after multiple replacements, the precision of the connection between the dental crown 3 and the abutment body 2 can be always maintained under the action of the arc edge of the movable block 10.

[0031] Refer to Figure 4 and 5 As shown in FIGS. 7 and 8, a rotating assembly is installed in the middle of the abutment body 2. The rotating assembly includes a connecting block 16. The connecting block 16 is fixedly connected to one end of the bidirectional threaded rod 12. A sliding rod 11 is fixedly connected to the middle of the abutment body 2. The threaded block 13 is slidably connected to the outer periphery of the sliding rod 11. A cross slot is provided on the side of the connecting block 16 away from the bidirectional threaded rod 12.

[0032] During use, insert a screwdriver into the middle of the abutment body 2 and slide it into the cross slot of the connecting block 16, so that the bidirectional threaded rod 12 can be quickly rotated, and under the action of the sliding rod 11, the threaded block 13 is prevented from rotating together with the bidirectional threaded rod 12, thereby improving the convenience of disassembling and installing the dental crown 3.

[0033] Refer to Figure 1 、 3 As shown in FIGS. 16 and 6, clamping blocks 8 are fixedly connected to the opposite sides of the mounting base 4 and the abutment body 2. Slots 7 are provided on the opposite sides of the mounting base 4 and the abutment body 2. The clamping blocks 8 are slidably connected to the middle of the slots 7. A through hole 5 is provided in the middle of the abutment body 2. A sealing ring 14 is fixedly connected to the outer periphery of the connecting block 16. The sealing ring 14 is rotatably connected to the middle of the inner wall of the through hole 5.

[0034] During use, after aligning the insertion block 18 with the slot 9 and inserting it into the abutment body 2, the clamping blocks 8 at the bottom of the mounting base 4 and the top of the abutment body 2 will respectively insert into the slots 7 in the middle of the mounting base 4 and the abutment body 2, thereby improving the sealing performance at the connection between the mounting base 4 and the abutment body 2, reducing the infiltration of moisture from the connection into the middle of the abutment body 2. At the same time, under the action of the sealing ring 14, it can be avoided that moisture seeps into the interior of the abutment body 2 from the through hole 5 when the connecting block 16 rotates, thereby reducing the erosion of the middle of the abutment body 2 by moisture and prolonging the service life of the abutment body 2.

[0035] Working principle: Insert the screwdriver through the through hole 5 to contact the connecting block 16, so that the screwdriver can drive the bidirectional threaded rod 12 to rotate, facilitating the bidirectional threaded rod 12 to drive the two threaded blocks 13 to move towards each other. When the threaded block 13 moves, it drives the movable block 10 to move together, thereby pulling out the movable block 10 from the middle of the insertion block 18. Conversely, the movable block 10 can be inserted into the middle of the insertion block 18, improving the convenience of installing and disassembling the dental crown 3.

[0036] When the screwdriver drives the connecting block 16 to rotate, it drives the sealing ring 14 to rotate together, so as to prevent moisture from entering the middle of the abutment body 2 under the action of the two sealing rings 14. At the same time, after the dental crown 3 is installed, the clamping blocks 8 on the mounting seat 4 and the abutment body 2 will respectively insert between the two clamping grooves 7, thereby improving the sealing performance between the mounting seat 4 and the abutment body 2, preventing the middle of the abutment body 2 from being eroded by moisture, and prolonging the service life of the abutment body 2.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
