Description

Technical Field

[0001] The utility model relates to the technical field of dental implantation, in particular to an anti-rotation base for dental implantation. Background Art

[0002] As people's living standards improve, the requirements for tooth care are getting higher and higher. When teeth are severely damaged and cannot be used, dental implant technology is often used for treatment. Dental implants are also called artificial dental implants. The implant is surgically implanted into the alveolar bone of the edentulous area, and then the abutment is installed on the implant, and finally the crown is installed on the abutment. Since the bottom of the existing abutment is cylindrical, it is easy for the abutment to rotate relative to the implant when it is installed in the implant, which is not conducive to later installation.

[0003] The existing patent (Announcement No.: CN209808586U) proposes a dental implant abutment, including an implant and an abutment, the abutment including a lower connecting part connected to the implant and an upper connecting part for connecting to a denture, the top of the implant is provided with a connecting groove that matches the lower connecting part, the upper end surface of the upper connecting part is provided with a through hole, the through hole extends downward and passes through the lower connecting part, the upper connecting part is provided with a screw, the connecting groove is provided with a threaded groove that matches the screw, the screw passes through the through hole and matches the threaded groove. An installation groove is provided on the wall of the connecting groove, an elastic sheet is provided in the installation groove, the elastic sheet initially extends out of the installation groove, the elastic sheet can be retracted into the installation groove under compression, and a groove for the elastic sheet to engage is provided on the connecting part. The utility model has the effect of making the installation of the dental implant abutment more stable.

[0004] The above-mentioned dental implant abutment adopts a technical solution for solving the installation problem that a screw is provided on the upper connecting part, and a threaded groove is provided on the connecting groove to cooperate with the screw. The screw passes through the through hole and cooperates with the threaded groove. Although this solution can solve the installation problem, the bottom of the abutment is columnar, which makes it easy for the abutment to rotate relative to the implant if the threaded column at the bottom of the abutment is not tightly installed with the implant. Therefore, we propose an anti-rotation abutment for dental implants to solve the above problem. Utility Model Content

[0005] The utility model provides an anti-rotation base for dental implantation, which solves the technical problem that the current dental implant base has no anti-rotation effect.

[0006] In order to solve the above technical problems, the utility model provides an anti-rotation abutment for dental implants, including a base body, the base body also including a mounting portion connected to the tooth crown, an anti-rotation portion connected to the bone-level implant, and a fixing portion for fixing the anti-rotation portion in the bone-level implant, the mounting portion and the anti-rotation portion are both provided with a cavity, the cavity extends from the top of the mounting portion to the bottom of the anti-rotation portion, the mounting portion is arranged at the top of the anti-rotation portion and fixedly connected to the anti-rotation portion, the anti-rotation portion is fitted and clamped in the bone-level implant, one end of the fixing portion is arranged in the cavity opened by the anti-rotation portion, and the other end of the fixing portion extends out of the cavity and is fixed in the bone-level implant.

[0007] Preferably, the anti-rotation portion comprises a base, a fixing column is fixed to the bottom of the base, a hexagonal prism is fixed to the bottom of the fixing column, and the fixing column and the hexagonal prism are both cooperated and clamped in the bone level implant.

[0008] The above technical solution is adopted: the anti-rotation part includes a base, a fixing column is fixed at the bottom of the base, a hexagonal prism is fixed at the bottom of the fixing column, and the fixing column and the hexagonal prism are both cooperated and clamped in the bone-level implant. Since each corner of the hexagonal prism conflicts with the clamping part in the bone-level implant, it can effectively prevent the base body from rotating relative to the bone-level implant due to improper tightening when it is fixed in the bone-level implant.

[0009] Preferably, a through hole is provided at the bottom of the anti-rotation portion and along the center direction of the cavity.

[0010] The above-mentioned technical solution is adopted: a through hole is opened through the bottom of the anti-rotation part and along the center direction of the cavity, and the through hole is used to penetrate the fastening part, so that one end of the fastening part is arranged in the cavity opened by the anti-rotation part, and the other end of the fastening part extends out of the cavity and is fixed in the bone-level implant, thereby achieving the fixation of the abutment body in the bone-level implant.

[0011] Preferably, the size of the through hole is smaller than the size of the cross section of the top end of the fixing portion.

[0012] By adopting the above technical solution: the size of the through hole is smaller than the size of the top cross-section of the fixing part, so that the abutment body will not be separated from the fixing part. When the fixing part is firmly fixed in the bone-level implant, the abutment body is also firmly fixed in the bone-level implant.

[0013] Preferably, a through hole is provided at the bottom of the anti-rotation portion, and the mounting portion is provided with a first demarcation groove and a second demarcation groove in sequence from top to bottom, the first demarcation groove is arranged above the second demarcation groove, and threads are provided from the top of the mounting portion to the first demarcation groove, from the first demarcation groove to the second demarcation groove, and from the second demarcation groove to the bottom of the mounting portion.

[0014] The above technical solution is adopted: a through-hole is opened at the bottom of the anti-rotation part, and the first dividing groove and the second dividing groove are opened in sequence from top to bottom on the mounting part, and the first dividing groove is arranged above the second dividing groove. According to the height of the first dividing groove and the second dividing groove arranged on the mounting part, it can be judged whether the mounting part can be completely installed in the crown. Threads are opened from the top of the mounting part to the first dividing groove, from the first dividing groove to the second dividing groove, and from the second dividing groove to the bottom of the mounting part, so as to facilitate the fixation of the crown.

[0015] Preferably, inclined surfaces are provided on both sides of the mounting portion, and equally spaced scale lines are provided on the inclined surfaces.

[0016] The above technical solution is adopted: inclined surfaces are opened on both sides of the installation part, and equally spaced scale lines are arranged on the inclined surfaces, so that the implantation depth of the crown can be easily known.

[0017] Compared with the related art, the utility model has the following beneficial effects:

[0018] 1. Compared with the traditional dental implant abutment, the utility model is provided with an anti-rotation part. When the abutment body is inserted on the bone-level implant, since the bottom of the traditional abutment body is a columnar structure, when the abutment body is fixed, if it is not fastened firmly, it is easy for the abutment body and the bone-level implant to rotate relative to each other, and finally the abutment body and the bone-level implant will shake or even fall off. However, the utility model adopts a hexagonal column structure, so that each corner of the hexagonal column can conflict with the inside of the bone-level implant, so the abutment body will not rotate relative to the bone-level implant. At the same time, it is also very convenient to fix the crown on the abutment body in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment 1

[0026] like Figure 1-Figure 4 As shown, an anti-rotation abutment for dental implantation comprises an abutment body 1, the abutment body 1 further comprises a mounting portion 2 connected with a crown 4, an anti-rotation portion 3 connected with a bone-level implant 6, and a fixing portion 5 fixing the anti-rotation portion 3 in the bone-level implant 6, a cavity 7 is provided in both the mounting portion 2 and the anti-rotation portion 3, the cavity 7 extends from the top of the mounting portion 2 to the bottom of the anti-rotation portion 3, the mounting portion 2 is arranged at the top of the anti-rotation portion 3 and is fixedly connected with the anti-rotation portion 3, the anti-rotation portion 3 is fitted and clamped in the bone-level implant 6, one end of the fixing portion 5 is arranged in the cavity 7 provided in the anti-rotation portion 3, and the other end of the fixing portion 5 extends out of the cavity 7 and is fixed in the bone-level implant 6;

[0027] The base body 1 also includes a mounting portion 2 that is connected to the crown 4, an anti-rotation portion 3 that is connected to the bone-level implant 6, and a fixing portion 5 that fixes the anti-rotation portion 3 in the bone-level implant 6. A cavity 7 is provided in the mounting portion 2 and the anti-rotation portion 3. The cavity 7 extends from the top of the mounting portion 2 to the bottom of the anti-rotation portion 3. The mounting portion 2 is arranged at the top of the anti-rotation portion 3 and is fixedly connected to the anti-rotation portion 3. The anti-rotation portion 3 is fitted in the bone-level implant 6. One end of the fixing portion 5 is arranged in the cavity 7 provided in the anti-rotation portion 3, and the other end of the fixing portion 5 extends out of the cavity 7 and is fixed in the bone-level implant 6. When When the abutment body 1 is inserted on the bone-level implant 6, since the bottom of the traditional abutment body 1 is a columnar structure, when the abutment body 1 is fixed, if it is not fastened firmly, it is easy for the abutment body 1 and the bone-level implant 6 to rotate relative to each other, and finally the abutment body 1 and the bone-level implant 6 to shake or even fall off. The present invention adopts a hexagonal column structure, so that each corner of the hexagonal column can conflict with the inside of the bone-level implant 6. Therefore, the abutment body 1 will not rotate relative to the bone-level implant 6. At the same time, it is also very convenient to fix the crown 4 on the abutment body 1 in the later stage.

[0028] Embodiment 2

[0029] like Figure 1-Figure 4As shown, the anti-rotation part 3 includes a base 21, a fixing column 22 is fixed at the bottom of the base 21, a hexagonal prism 23 is fixed at the bottom of the fixing column 22, the fixing column 22 and the hexagonal prism 23 are both matched and clamped in the bone level implant 6, a through hole 8 is opened at the bottom of the anti-rotation part 3 and along the center direction of the cavity 7, the size of the through hole 8 is smaller than the size of the cross-section of the top end of the fixing part 5, and the through hole 8 is opened at the bottom of the anti-rotation part 3. The mounting part 2 is sequentially opened with a first demarcation groove 33 and a second demarcation groove 34 from top to bottom, the first demarcation groove 33 is arranged above the second demarcation groove 34, and threads 31 are opened from the top of the mounting part 2 to the first demarcation groove 33, from the first demarcation groove 33 to the second demarcation groove 34, and from the second demarcation groove 34 to the bottom of the mounting part 2, and inclined surfaces 32 are opened on both sides of the mounting part, and equally spaced scale lines 35 are arranged on the inclined surfaces 32, so as to conveniently know the implantation depth of the crown 4;

[0030] A fixing column 22 is fixed to the bottom of the base 21, and a hexagonal prism 23 is fixed to the bottom of the fixing column 22. The fixing column 22 and the hexagonal prism 23 are both matched and clamped in the bone-level implant 6. Since each corner of the hexagonal prism 23 is in conflict with the clamping in the bone-level implant 6, it can effectively prevent the abutment body 1 from rotating relative to the bone-level implant 6 due to improper fastening when the abutment body 1 is fixed in the bone-level implant 6.

[0031] The through hole 8 is used to penetrate the fastening part, so that one end of the fastening part is arranged in the cavity 7 opened in the anti-rotation part 3, and the other end of the fastening part extends out of the cavity 7 and is fixed in the bone-level implant 6, thereby fixing the abutment body 1 in the bone-level implant 6. The size of the through hole 8 is smaller than the size of the top cross-section of the fixing part 5, so that the abutment body 1 will not be separated from the fixing part 5. When the fixing part 5 is firmly fixed in the bone-level implant 6, the abutment body 1 is also firmly fixed in the bone-level implant 6.

[0032] Working principle: Figure 1-4 As shown, the bone-level implant 6 is implanted on the alveolar bone, and then the anti-rotation portion 3 in the abutment body 1 is inserted into the bone-level implant 6. By tightening the fixing portion 5, the abutment body 1 is fixed in the bone-level implant 6. At the same time, since there is a hexagonal prism 23 in the anti-rotation portion 3, each corner of the hexagonal prism 23 will conflict with the bone-level implant 6, effectively preventing the abutment body 1 and the bone-level implant 6 from relative rotation. Then the crown 4 is installed on the mounting portion 2 in the abutment body 1 to complete the tooth implantation.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
