Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, specifically a flexible screw channel screw retention abutment. Background Technology

[0002] Dental implants involve implanting a replacement for natural tooth roots into the jawbone to obtain a restoration similar to tooth retention and support. It is a method of tooth restoration that uses a structure implanted within the bone tissue to support and fix the superstructure. The implant is placed into the alveolar bone and eventually fuses with the surrounding bone tissue to form a stable osseointegration. An abutment is then installed on the implant, and finally, the superstructure is installed on the abutment to restore missing or damaged teeth.

[0003] In the prior art, patent announcement number CN205054475U discloses a highly stable dental implant structure, including an implant that is inserted into the alveolar bone. The implant has a stepped positioning hole, and the lower part of the abutment is inserted into a larger portion above the positioning hole. The abutment has a stepped inner hole. A central bolt is inserted through this stepped inner hole into the lower part of the positioning hole in the implant, forming a threaded engagement. A spring washer is placed between the head of the central bolt and the stepped surface of the stepped inner hole, and the central bolt locks the spring washer and the abutment to the implant.

[0004] The aforementioned device uses a central bolt to lock the spring washer and abutment onto the implant. The bolt and abutment are in rigid contact, which cannot eliminate the risk of crown wear and breakage due to occlusal forces. Furthermore, after prolonged use, crowns accumulate plaque and bacteria in the mouth, but they are difficult to remove quickly for thorough cleaning and maintenance. Therefore, a flexible screw-channel screw-retaining abutment is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an elastic screw channel screw retention base to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible screw channel screw retention abutment, including an implant, an external thread on the outer side of the implant, a mating screw hole on the inner side of the implant, a crown mounted on the top of the implant, an abutment assembly connected to the implant, the abutment assembly including an abutment body connected to the implant, an anti-rotation boss connected to the abutment body, an elastic claw fixedly mounted on the upper end of the anti-rotation boss, and a mating assembly fixedly mounted inside the crown.

[0007] Preferably, the crown has an installation groove, and the docking assembly is installed on the crown through the installation groove.

[0008] Preferably, the crown has an installation groove, and the docking assembly is installed on the crown through the installation groove.

[0009] Preferably, the mounting screw is connected to the implant via a mating screw hole, the abutment body is mounted on the abutment body via the mounting screw, the connecting screw is connected to the abutment body via the abutment screw hole, and the anti-rotation boss is mounted on the abutment body via the connecting screw.

[0010] Preferably, the docking assembly includes a docking seat fixedly installed inside the crown, the docking seat having a docking interface, the inner wall of the docking interface having a limiting groove, the top of the docking interface being fixedly installed with an installation base, the installation base having spaced-out shrinkage grooves, and the installation base having a limiting boss fixedly installed.

[0011] Preferably, the gap between the elastic claws is equal to the width of the limiting boss, and the mating interface is wider at the bottom and narrower at the top.

[0012] Preferably, the anti-rotation boss is connected to the docking seat via a mating interface, the elastic claw is embedded in the docking seat via a limiting slot, and the limiting boss is embedded in the gap between the elastic claws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this application, after precise alignment of the mounting screw and the mating screw hole, the abutment body can be rotated to achieve its installation on the implant. After the abutment body is installed, the connecting screw and the abutment screw hole must be precisely aligned, and then the anti-rotation boss is rotated to complete its installation on the abutment body. Next, the crown is pressed against the anti-rotation boss. After the crown is pressed, the elastic claw will spring open and be fixed in the limiting slot, thereby achieving rapid crown installation. In addition, the user can lift the crown upwards for easy removal and cleaning.

[0015] In this application, during the process of the elastic claw entering the mating joint, it bends into the shrinkage groove, allowing it to smoothly enter the mating joint. When the elastic claw springs open and is fixed in the limiting slot, the limiting boss will embed into the gap between the elastic claws to prevent the crown from rotating and misaligning. Furthermore, the elastic claw has a certain degree of elasticity, ensuring effective retention force while maintaining elastic contact with the mating joint, eliminating the risk of crown wear and breakage due to occlusal forces.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an elastic screw channel screw retention abutment, including an implant 1, an external thread 2 on the outer side of the implant 1, a mating screw hole 3 on the inner side of the implant 1, a crown 4 mounted on the top of the implant 1, an abutment assembly 5 connected to the implant 1, and a mating assembly 6 fixedly mounted inside the crown 4. Through the ingenious cooperation of the carefully designed abutment assembly 5 and mating assembly 6, users can easily remove the crown 4 for thorough cleaning. This design not only improves the cleaning efficiency of the crown 4, but also effectively prevents the crown 4 from rotating or misaligning during reinstallation, ensuring the correct position and stability of the crown 4.

[0023] like Figure 2 and Figure 3As shown, the abutment assembly 5 includes an abutment body 501 connected to the implant 1. An anti-rotation boss 504 is connected to the abutment body 501. An elastic claw 505 is fixedly installed at the upper end of the anti-rotation boss 504. An abutment screw hole 502 is opened on the abutment body 501. A connecting screw 503 is fixedly installed at the bottom of the anti-rotation boss 504. A silicone pad 506 is sleeved on the anti-rotation boss 504. An installation screw 507 is fixedly installed at the bottom of the abutment body 501. An installation groove is opened on the crown 4. The docking assembly 6 is installed on the crown 4 through the installation groove. The abutment body 501 is installed on the abutment body 501 through the installation screw 507. The connecting screw 503 is connected to the abutment body 501 through the abutment screw hole 502. The anti-rotation boss 504 is installed on the abutment body 501 through the connecting screw 503.

[0024] Specifically, during dental restoration surgery, the first step is to precisely align and insert the mounting screw 507 into the docking screw hole 3. Once the mounting screw 507 is correctly aligned with the docking screw hole 3, the next step is to rotate the abutment body 501. By rotating, the abutment body 501 can be installed onto the implant 1. After the abutment body 501 is successfully installed onto the implant 1, the next step is to align the connecting screw 503 with the abutment screw hole 502. When the connecting screw 503 is aligned with the abutment screw hole 502, the anti-rotation boss 504 needs to be rotated so that the anti-rotation boss 504 can be installed onto the abutment body 501. After installation, the crown 4 needs to be pressed onto the anti-rotation boss 504. Once the crown 4 is correctly pressed onto the anti-rotation boss 504, the elastic claw 505 will automatically spring open and be fixed in the limiting slot 602, thus achieving quick installation of the crown 4. In addition, the user can lift the crown 4 upwards when needed for easy removal for cleaning and maintenance.

[0025] like Figure 2 and Figure 4 As shown, the docking assembly 6 includes a docking seat 601 fixedly installed inside the crown 4. The docking seat 601 has a docking interface 603. A limiting groove 602 is provided on the inner wall of the docking interface 603. An installation base 604 is fixedly installed on the top of the docking interface 603. A shrinkage groove 606 is provided on the installation base 604 at intervals. A limiting boss 605 is fixedly installed on the installation base 604. The gap between the elastic claws 505 is equal to the width of the limiting boss 605. The docking interface 603 is wider at the bottom and narrower at the top.

[0026] Specifically, during the process of the elastic claw 505 entering the interface 603, it bends into the shrinkage groove 606, which makes it very easy for the elastic claw 505 to enter the interface 603. When the elastic claw 505 springs back and is fixed in the limiting slot 602, the limiting boss 605 will be embedded in the gap between the elastic claws 505. This mechanism effectively prevents the crown 4 from rotating and misaligning.

[0027] Working principle: First, implant 1 is inserted into the jawbone. Then, the mounting screw 507 is aligned with the docking screw hole 3. After alignment, the abutment body 501 is rotated to install it onto implant 1. Once the abutment body 501 is correctly installed, the next step is to carefully align the connecting screw 503 with the abutment screw hole 502. Once the connecting screw 503 is aligned with the abutment screw hole 502, the next step is to rotate the anti-rotation boss 504. Rotation ensures the anti-rotation boss 504 is securely installed on the abutment body 501. Then, the crown 4 is pressed onto the anti-rotation boss 504. After pressing the crown 4 onto the anti-rotation boss 504, the elastic claw 505 springs open and locks into the limiting slot 602, enabling quick installation of the crown 4. The user can then lift the crown 4 upwards for easy removal and cleaning. During the process of the elastic claw 505 entering the interface 603, it will bend into the shrinkage groove 606, so that the elastic claw 505 can easily enter the interface 603. When the elastic claw 505 springs out and is fixed in the limiting slot 602, the limiting boss 605 will be embedded in the gap between the elastic claws 505 to prevent the crown 4 from rotating and misaligning.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
