Description

Technical Field

[0001] This invention relates to the field of dental implant technology, and more specifically, to a dental implant that is easy to implant. Background Technology

[0002] A dental implant is a type of dental prosthesis. Patients can have dental implants installed and fixed by dental implantation technology. The artificial tooth root is implanted into the alveolar bone at the site of the missing tooth. After it integrates with the bone, a crown that is similar in shape to a natural tooth is then installed.

[0003] A search revealed CN216257514U, which discloses an implant kit for facilitating dental implantation. The kit describes a structure comprising an implant and an abutment. The implant has a groove at its end, the groove extending along the implant's axis. A first limiting step protrudes from the sidewall of the groove, with a gap between the first limiting step and the bottom of the groove. The abutment has a through hole extending along its axis, with a second limiting step protruding from the sidewall of the through hole. The kit also includes a clamping component for fixing the first and second limiting steps together. This implant kit for facilitating dental implantation has a reasonable structure, improves the stability of the connection between the implant and the abutment, prevents loosening over long-term use, and improves the quality and reliability of the dental implant structure.

[0004] The above-mentioned patent still has shortcomings in actual use. When using the existing technology to install the implant, it is necessary to continuously rotate the installation angle of the crown. When fixing the crown, the tooth may shift due to the rotation of the fixing screw. In addition, when replacing a damaged implant, the entire implant needs to be removed from the gum, which is cumbersome and results in a poor patient experience.

[0005] Based on this, this utility model discloses a dental implant that is easy to implant. Utility Model Content

[0006] To address the problems mentioned in the background art, such as the need for constant rotation of the crown during implant placement using existing techniques, tooth misalignment during final fixation, and the cumbersome and unpleasant procedure of removing the entire implant from the gum when replacing a damaged one, this invention provides a convenient dental implant. The implant includes a fastening screw, with an implant base fixedly connected to its top. A crown is mounted on the top of the implant base. A limiting component is installed on both the implant base and the crown. This limiting component includes... The implant base has a rotating groove located at its lower part, and a rotating collar is fitted in the rotating groove. A fixing block is fixed to the outer arc surface of the rotating collar. Both ends of the fixing block have telescopic holes. A limit spring is connected inside each telescopic hole, and a push rod is connected to the end of each limit spring. A limit block is fixed to the end of each push rod. An installation hole is opened through the top of the crown. A limit groove is opened at the lower part of the cavity of the installation hole. Limit holes are symmetrically opened on the top two structural surfaces of the limit groove. A positioning component is installed inside the rotating collar.

[0007] As a further improvement to this technical solution, the positioning component includes a lifting cavity, the bottom end face of the rotating collar is provided with the lifting cavity, the top of the inner wall of the lifting cavity is connected with a telescopic spring, the bottom of the telescopic spring is connected with a lifting block, a card is fixedly attached to the bottom end face of the lifting block, and slots are provided at equal intervals on the bottom end face of the inner wall of the rotating groove.

[0008] As a further improvement to this technical solution, an insertion hole is provided inside the rotating collar at a position slightly lower than the lifting cavity. The opening space of the insertion hole extends through the opening range of the lifting cavity. An insertion rod can be installed inside the insertion hole, and a positioning rod is fixedly connected to the end of the insertion rod.

[0009] As a further improvement to this technical solution, after the insertion rod is fully inserted into the socket, the telescopic spring is in a compressed state, and the bottom of the card is tightly attached to the top of the insertion rod. When the telescopic spring does not deform, the bottom of the card extends out of the opening space of the lifting cavity.

[0010] As a further improvement to this technical solution, the top of the planting base is provided with a threaded hole, and a fastening bolt can be installed on the top of the threaded hole. The diameter of the nut section at the top of the fastening bolt is the same as the diameter of the section at the top of the space where the mounting hole is opened.

[0011] As a further improvement to this technical solution, the limiting spring does not deform when it is not in operation, and at this time the distance between the farthest ends of the two limiting blocks is less than the opening width at the bottom of the limiting groove. When the distance between the two limiting blocks is the closest, the distance between the farthest ends of the two limiting blocks is the same as the opening width at the top of the limiting groove.

[0012] Compared with existing technologies, the beneficial effects of this utility model are:

[0013] 1. In this type of dental implant that is easy to implant, the positioning effect is achieved during the installation of the crown through the cooperation of the limiting component. There is no need to constantly adjust the installation angle of the crown, ensuring that the crown will not shift when it is fixed. When replacing the crown, an opening can be made directly on the crown near the opening position of the limiting slot, so that the limiting block can be disengaged from the limiting hole, which facilitates the subsequent replacement of the crown without replacing the entire implant. The operation is simple and reduces the pain of tooth replacement for patients.

[0014] 2. In this type of dental implant that is easy to implant, the positioning components are designed to automatically adjust the angle during the downward installation of the crown, so as to achieve the effect of pre-positioning the crown during installation. Attached Figure Description

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Therefore, this utility model provides a dental implant that is easy to implant, see [link to relevant documentation]. Figures 1-4 As shown, it includes a fastening screw 1, with an implant base 2 fixedly connected to the top of the fastening screw 1. A crown 3 can be installed on the top of the implant base 2. Limiting components are installed on the implant base 2 and the crown 3. The limiting components include a rotating groove 5. The rotating groove 5 is opened at the lower part of the cone-shaped body of the implant base 2. A rotating collar 6 is fitted in the rotating groove 5. A fixing block 7 is fixedly connected to the outer arc surface of the rotating collar 6. Both ends of the fixing block 7 are provided with telescopic holes 8. A limiting spring 9 is connected inside each telescopic hole 8. A push rod 10 is connected to the end of each limiting spring 9. A limiting block 11 is fixedly connected to the end of each push rod 10. An installation hole 12 is opened through the top of the crown 3. A limiting groove 13 is opened at the lower part of the cavity of the installation hole 12. Limiting holes 14 are symmetrically opened on the top two structural surfaces of the limiting groove 13. A positioning component is installed inside the collar 6. The inclination angle of the rotating collar 6 arc surface is the same as the inclination angle of the conical arc surface of the implant base 2. The diameter of the telescopic hole 8 is slightly larger than the diameter of the push rod 10. The vertical cross-section of the limiting block 11 is a right trapezoid that is narrower at the top and wider at the bottom, and the inclined surface can contact the bottom edge of the inner wall of the limiting groove 13. The vertical cross-section of the cavity of the limiting groove 13 is a trapezoid that is wider at the bottom and narrower at the top. After the limiting block 11 enters the opening space of the limiting groove 13, as the crown 3 moves downward, the limiting block 11 moves within the inner wall of the limiting groove 13. As the cavity on both sides of the limiting groove 13 contracts, the end of the limiting block 11 intersects with the inclined surface of the inner wall of the limiting groove 13, thereby adjusting the horizontal displacement of the crown 3 during its descent and achieving a pre-positioning effect when the crown 3 moves downward. When replacing a damaged crown 3, a side opening of the limiting groove 13 can be made in the crown 3 to release the limiting effect of the limiting block 11 and the limiting hole 14, eliminating the need to replace the entire implant, making the operation convenient and reducing patient pain.

[0025] The top of the implant base 2 has a threaded hole 15, and a fastening bolt 4 can be installed on the top of the threaded hole 15. The diameter of the nut section at the top of the fastening bolt 4 is the same as the diameter of the section at the top of the space opened in the mounting hole 12. After the crown 3 is inserted into the implant base 2, the fastening bolt 4 can pass through the mounting hole 12 in the crown 3 and enter the interior of the threaded hole 15. Then, the fastening bolt 4 is rotated to fix the crown 3.

[0026] When the limiting spring 9 is not in operation, it does not deform, and at this time the distance between the farthest ends of the two limiting blocks 11 is less than the opening width at the bottom of the limiting groove 13. When the distance between the two limiting blocks 11 is the closest, the distance between the farthest ends of the two limiting blocks 11 is the same as the opening width at the top of the limiting groove 13.

[0027] During operation, the fastening screw 1 is installed inside the alveolar bone through the structural design of the limiting component, and the implant base 2 is installed on the fastening screw 1. Then, the limiting groove 13 is brought close to the limiting block 11, and a downward force is applied to the crown 3, so that the mounting hole 12 is fitted onto the outside of the implant base 2 and gradually moves downward. During this process, the limiting block 11 enters the bottom opening space of the limiting groove 13. As the crown 3 moves downward, the limiting block 11 intersects with the two inclined surfaces of the limiting groove 13 and applies pressure to the limiting block 11. The limiting spring 9 is compressed and generates a reaction force. When the limiting block 11 moves to the opening range of the limiting hole 14, the reaction force of the limiting spring 9 pushes the limiting block 11 into the limiting hole 14, thereby adjusting the horizontal offset of the crown 3 during its descent. This achieves the positioning effect of the crown 3 during its downward movement without the need to constantly adjust the installation angle of the crown 3, avoiding the phenomenon of offset when the crown 3 is finally fixed.

[0028] Further, see Figure 1 , Figures 5-6 As shown, the positioning assembly includes a lifting cavity 16. The lifting cavity 16 is formed on the bottom end face of the rotating collar 6. A telescopic spring 17 is connected to the top of the inner wall of the lifting cavity 16, and a lifting block 18 is connected to the bottom of the telescopic spring 17. A card 19 is fixed to the bottom end face of the lifting block 18. A slot 20 is formed at equal intervals on the bottom end face of the inner wall of the rotating groove 5. Before the crown body 3 is installed, the telescopic spring 17 is in a compressed state, and the card 19 tends to move downward. The horizontal cross-section of the lifting block 18 is the same as the horizontal cross-section of the lifting cavity 16, which can ensure that the downward movement trajectory of the card 19 will not deviate. After the card 19 is inserted into the slot 20, the telescopic spring 17 returns to its original length, and the lifting block 18 is still located inside the lifting cavity 16. The card 19 can assist the rotating collar 6 in not rotating along the rotating groove 5, ensuring that the rotating collar 6 is stationary when the crown body 3 is installed, and realizing the preset installation position of the crown body 3.

[0029] An insertion hole 21 is provided inside the rotating collar 6, located slightly below the lifting cavity 16. The space of the insertion hole 21 extends through the opening range of the lifting cavity 16. An insertion rod 22 can be installed inside the insertion hole 21, and a positioning rod 23 is fixedly connected to the end of the insertion rod 22. The insertion hole 21 can limit the downward movement of the card 19, and the positioning rod 23 can fine-tune the working position of the rotating collar 6 to ensure that the subsequent installation position of the crown 3 meets the requirements.

[0030] After the insertion rod 22 is fully inserted into the socket 21, the telescopic spring 17 is compressed, and the bottom of the card 19 is tightly against the top of the insertion rod 22. When the telescopic spring 17 does not deform, the bottom of the card 19 extends out of the opening space of the lifting cavity 16. Before the crown body 3 is installed, the insertion rod 22 is always located inside the socket 21.

[0031] During operation, through the structural design of the positioning component, before the crown 3 is installed, the angle of the positioning rod 23 is adjusted. The rotating collar 6 drives the fixing block 7 to rotate along the rotating groove 5, so that the two ends of the positioning rod 23 contact the teeth on both sides of the implant groove. Then, an outward pulling force is applied to the positioning rod 23, causing the insertion rod 22 to disengage from the insertion hole 21. Under the push of the reaction force of the compressed telescopic spring 17, the lifting block 18 pushes the card 19 to insert into the corresponding card slot 20, thereby limiting the rotating collar 6 and thus achieving the limiting effect of the fixing block 7 and the limiting block 11. This allows the limiting block 11 to move along the opening space of the limiting groove 13, achieving the pre-positioning effect when the crown 3 is installed.

[0032] In summary, this effectively solves the problems of existing implant installation techniques, which sometimes require constant rotation of the crown, tooth misalignment during final fixation, and the need to remove the entire implant from the gum when replacing a damaged one, resulting in a cumbersome procedure and poor patient experience.
