Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to an implant abutment. Background Technology

[0002] In the field of dental implantology, the implant abutment, as a key component connecting the implant and the superstructure, directly affects the outcome of implant restoration and the patient's comfort.

[0003] Traditional implant abutments typically use a threaded connection between the implant body and the abutment body. However, this connection method has several drawbacks in clinical practice. Since the implant is also connected to the jawbone via threads, when the abutment is screwed into the implant: the abutment applies torque to the implant. If the direction of this torque is the same as the direction of the threads connecting the implant and the jawbone, it can easily cause the abutment to deform or break. If the direction of the torque is opposite to the direction of the threads, rotating the abutment can easily cause the implant to rotate, loosening the connection between the implant and the jawbone, which also affects the implantation outcome. Utility Model Content

[0004] The main purpose of this invention is to propose an implant abutment that aims to solve the problem that the spiral connection between the abutment and the implant in existing implant abutments has an adverse effect on the planting effect and the abutment itself.

[0005] To address the aforementioned issues, this utility model proposes an implant abutment, comprising an abutment body for connecting an artificial crown and an implant body for connecting to the jawbone. The implant body is mounted on the bottom end of the abutment body, and the bottom end of the abutment body is provided with a locking block for connecting the implant body and the abutment body. The locking block is embedded in the inner wall of a slot, the slot is formed on the inner wall of an installation groove, and the installation groove is formed at the top end of the implant body.

[0006] In one embodiment, the card blocks are evenly distributed in a circular array at the bottom end of the base body;

[0007] The card block is slidably installed on the inner wall of the slide groove, which is located at the bottom of the base body.

[0008] In one embodiment, a push rod is fixedly installed on one side of the card block, and the push rod passes through a groove and is placed on the inner wall of the base body.

[0009] In one embodiment, the push rod abuts against the fixed rod, and the fixed rod is slidably mounted on the inner wall of the base body.

[0010] In one embodiment, a vertical rod for positioning and guidance is fixedly installed at the bottom end of the base body. The vertical rod is embedded in the inner wall of the fixing groove, which is opened at the top of the implant body. An annular groove is provided at the opening of the fixing groove.

[0011] In one embodiment, the end of the push rod is inclined, and the inclined surface has the same inclination angle as the inclined surface at the bottom end of the fixed rod.

[0012] In one embodiment, the maximum length of the push rod to the side wall of the block is equal to the length between the two sides of the inner wall of the groove.

[0013] In one embodiment, the outer wall of the push rod is roughened.

[0014] Beneficial effects: The technical solution of this utility model changes the connection method between the implant body and the abutment body, which will not damage the abutment, reduces the risk of mechanical damage to the gingival tissue around the implant, reduces the operation difficulty for medical staff, and will not cause the implant to rotate during the operation, thus effectively improving the implantation effect.

[0027] This utility model proposes an implant abutment with a locking block 8 and a locking groove 10, which can directly insert the abutment body 2 into the implant body 1 for fixation. This prevents the implant body 1 from rotating during installation, thus affecting the connection between the implant body 1 and the gum, thereby reducing the risk of mechanical damage to the gingival tissue around the implant.

[0028] In this embodiment, the structure of the dental implant is as follows: Figures 1-4 As shown, where Figures 1-4Only a portion of the dental implant is shown, primarily highlighting the parts relevant to this invention. The dental implant of this invention comprises an implant body 1 and an abutment body 2.

[0029] like Figures 2-4 As shown, the implant abutment includes an abutment body 2 for connecting to the artificial crown and an implant body 1 for connecting to the jawbone. The implant body 1 is installed at the bottom of the abutment body 2. The bottom of the abutment body 2 has a retaining block 8 for connecting the implant body 1 and the abutment body 2. The retaining block 8 is embedded in a retaining groove 10, which is located on the inner wall of a mounting groove 13, which is located at the top of the implant body 1. Clearly, because the implant and jawbone are connected by threads, and the existing abutment and implant are also connected by threads, when the abutment is screwed into the implant, the abutment applies torque to the implant. If the direction of the torque is the same as the direction of the thread, it can easily lead to deformation and breakage of the abutment. Deformation of the abutment will affect the placement and stability of the restoration, thus affecting aesthetics and function. If the direction of the torque is opposite to the direction of the thread, rotating the abutment can easily cause the implant to rotate, leading to loosening of the connection between the implant and the jawbone. The connection method proposed in this embodiment only applies compressive force to the implant during installation, without applying torsional force, thereby improving the stability of the connection between the implant and the jawbone.

[0030] In this embodiment, as Figures 2-4 As shown, the locking blocks 8 are evenly distributed in a circular array at the bottom of the base body 2. The locking blocks 8 are slidably installed on the inner wall of the sliding groove 12, which is located at the bottom of the base body 2. This design allows the position of the locking blocks 8 to be changed. During installation, the distance between the locking blocks 8 can be adjusted to make it easier to embed the locking blocks 8 into the mounting groove 13. After the locking blocks 8 are embedded in the designated position, the locking blocks 8 are opened by the fixing rod 3, thereby controlling the locking blocks 8 to be embedded into the interior of the mounting groove 13, thus connecting the implant body 1 and the base body 2 together. This allows medical personnel to easily embed the locking blocks 8 into the interior of the mounting groove 13 and to tightly connect the implant body 1 and the base body 2 together by simple compression, making the operation more convenient.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, a push rod 11 is fixedly installed on one side of the locking block 8. The push rod 11 passes through the slide groove 12 and is placed on the inner wall of the base body 2. This design can control the locking block 8 to slide on the inner wall of the slide groove 12. At the same time, the design of the push rod 11 can also control the movement of the locking block 8 by installing the fixing rod 3, thereby achieving fixation. Compared with directly setting the locking block 8 in a fixed position, the locking block 8 can be embedded into the inner wall of the mounting groove 13 by squeezing, which can reduce the squeezing force and facilitate the installation of the base.

[0032] Furthermore, the push rod 11 abuts against the fixing rod 3, and the fixing rod 3 is slidably installed on the inner wall of the base body 2. With this design, the push rod 11 can be pushed by the compression of the fixing rod 3, thereby controlling the opening of the locking block 8, thus realizing the fixation of the implant body 1 and the base body 2.

[0033] In this embodiment, the end of the push rod 11 is inclined, and the inclined surface has the same inclination angle as the inclined surface at the bottom of the fixed rod 3. This design allows for smoother insertion into the inner wall of the base body 2, preventing the locking block 8 from not moving to the designated position and causing the fixed rod 3 to get stuck on the inner wall of the base body 2.

[0034] In this embodiment, the maximum length of the push rod 11 to the side wall of the locking block 8 is equal to the length between the two sides of the inner wall of the slide groove 12. When the locking block 8 is moved to one side of the slide groove 12, the locking block 8 and the push rod 11 can be disassembled from the inner wall of the slide groove 12, so that the one-piece part can be transformed into two parts during production, reducing the production difficulty of the product.

[0035] In this embodiment, the outer wall of the push rod 11 is roughened. This design ensures that the position of the locking block 8 will not change after the position of the moving locking block 8 is moved without additional force. This avoids the situation where the position of the locking block 8 changes during installation, preventing the locking block 8 from being unable to embed into the inner wall of the mounting groove 13 and requiring readjustment of the locking block 8, which would necessitate repeated operations by medical personnel.

[0036] In this embodiment, a vertical rod 5 for positioning and guidance is fixedly installed at the bottom of the base body 2. The vertical rod 5 is embedded in the inner wall of the fixing groove 6. The fixing groove 6 is opened at the top of the implant body 1. An annular groove 7 is opened at the opening of the fixing groove 6. The cross-sectional shape of the vertical rod 5 can be various, as long as the vertical rod 5 is vertical. At the same time, the shape of the fixing groove 6 changes with the shape of the vertical rod 5. As long as the two match, the design can be such that when the base body 2 is installed, the vertical rod 5 is embedded in the inner wall of the annular groove 7. Then, the base body 2 is rotated so that the vertical rod 5 is embedded in the inner wall of the fixing groove 6. The position of the locking block 8 can be determined. So that after the locking block 8 is embedded in the inner wall of the installation groove 13, when the locking block 8 is opened, the locking block 8 can be embedded in the inner wall of the locking groove 10.

[0037] This utility model adopts a structure in which the card block 8 and the card slot 10 are engaged, and the vertical rod 5 and the fixing slot 6 are positioned and matched to achieve the connection between the base body 2 and the implant body 1. In the whole operation process, it is much more convenient than the spiral in the prior art, and does not have the series of problems caused by the spiral.

[0038] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
