Technical Field

[0001] The utility model relates to the technical field of artificial dental implants, and more specifically, to a detachable composite artificial dental implant. Background Art

[0002] A dental implant is a bionic tooth made of biological materials, which is divided into two parts: an implant that is implanted into the human jawbone to play a supporting and retaining role, and a dental crown that undertakes the chewing function. Doctors select an implant of a certain shape according to the changes of the alveolar bone and jawbone after the patient loses teeth, implant it into the jawbone as an artificial tooth root, and then install a dental crown on the implant post exposed in the oral cavity to obtain a shape and function similar to that of the natural tooth.

[0003] At present, when wearing a bionic crown for an artificial dental implant, the bionic crown is usually installed on the abutment by a strong bonding method. However, when the bionic crown is damaged and needs to be replaced, the strong bonding method between the bionic crown and the abutment will make it difficult to remove the bionic dental crown from the abutment, which is not convenient for replacing the bionic dental crown. Therefore, we propose a detachable composite artificial dental implant. Summary of the Utility Model

[0004] In order to overcome the above defects of the prior art, an embodiment of the present utility model provides a detachable composite artificial dental implant. The technical problem to be solved by the present invention is that: at present, artificial dental implants usually install the bionic crown on the abutment by a strong bonding method. However, when the bionic crown is damaged and needs to be replaced, the strong bonding method between the bionic crown and the abutment will make it difficult to remove the bionic dental crown from the abutment, which is not convenient for replacing the bionic dental crown.

[0005] To achieve the above object, the present utility model provides the following technical solution: a detachable composite artificial dental implant, including a dental crown and an implant disposed at the bottom of the dental crown. An installation mechanism connected to the dental crown and the implant is disposed inside the dental crown. The installation mechanism is used to connect the dental crown and the implant. A disassembly mechanism connected to the dental crown is further disposed inside the dental crown. The disassembly mechanism is used to separate the dental crown from the implant.

[0006] In a preferred embodiment, the installation mechanism includes a cavity disposed inside the dental crown. The cavity extends to the bottom of the dental crown. A fixing column extending into the cavity is fixedly connected to the top of the implant. A limiting arc-shaped block is fixedly connected to the top of the fixing column. The top of the limiting arc-shaped block is provided with an inclined surface structure.

[0007] In a preferred embodiment, the installation mechanism further includes installation chutes symmetrically arranged on both sides inside the dental crown. Telescopic springs are arranged inside both of the installation chutes. Limit sliders extending into the cavity are movably arranged inside both of the installation chutes, and the limit sliders are located at the bottom of the limit arc-shaped blocks.

[0008] In a preferred embodiment, the disassembly mechanism includes grooves symmetrically formed at both ends of the outer wall of the limit arc-shaped block. A connecting rod located below the limit arc-shaped block is fixedly connected to the outer wall of the fixing column. A translation chute is arranged at one end inside the dental crown. A driving rod is movably arranged inside the translation chute, and the driving rod is in contact with the connecting rod.

[0009] In a preferred embodiment, a docking groove is arranged at the bottom of one side of the translation chute, and a separation groove penetrating the dental crown is arranged at the other side of the bottom of the translation chute. The docking groove is located below the connecting rod.

[0010] In a preferred embodiment, a sealing layer is fixedly arranged on the surface of the dental crown by adhesion, and one end of the driving rod away from the fixing column extends into the sealing layer.

[0011] In a preferred embodiment, mounting baffles are fixedly connected to the top of the implant and the outer wall of the fixing column. A torsion spring is arranged on one side of the fixing column between the two mounting baffles, and both ends of the torsion spring abut against the two mounting baffles respectively.

[0012] Technical effects of the present utility model:

[0013] By providing the installation mechanism and the disassembly mechanism, when the surface of the dental crown is damaged, the vertical limit on the dental crown is released through the disassembly mechanism, and then the dental crown is pulled out for replacement. Furthermore, the vertical movement of the dental crown is limited by the two limit sliders in the installation mechanism fitting with the bottom of the limit arc-shaped block, completing the stable installation operation between the dental crown and the implant, avoiding the inconvenience of disassembling the adhesively bonded dental crown and the difficulty in replacing the dental crown when the dental crown is damaged and needs to be replaced.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art in the technical field of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-5 shown, the present utility model provides a detachable composite artificial dental implant, including a dental crown 1 and an implant 2 provided at the bottom of the dental crown 1. An installation mechanism connected to both the dental crown 1 and the implant 2 is provided inside the dental crown 1. The installation mechanism is used to connect the dental crown 1 and the implant 2. A disassembly mechanism connected to the dental crown 1 is also provided inside the dental crown 1. The disassembly mechanism is used to separate the dental crown 1 and the implant 2. The installation mechanism includes a cavity 14 provided inside the dental crown 1. The cavity 14 extends to the bottom of the dental crown 1. The top of the implant 2 is fixedly connected with a fixing column 4 extending into the cavity 14. The top of the fixing column 4 is fixedly connected with a limiting arc-shaped block 8. The top of the limiting arc-shaped block 8 is provided with an inclined surface structure. The installation mechanism further includes installation sliding grooves 5 symmetrically provided on both sides inside the dental crown 1. Telescopic springs 6 are provided inside both of the two installation sliding grooves 5. Limiting sliders 7 extending into the cavity 14 are movably provided inside both of the two installation sliding grooves 5. The limiting sliders 7 are located at the bottom of the limiting arc-shaped block 8. The limiting sliders 7 are elastically connected to the installation sliding grooves 5 through the telescopic springs 6.

[0022] As Figures 1-5 shown, the disassembly mechanism includes grooves 13 symmetrically opened at both ends of the outer wall of the limiting arc-shaped block 8. A connecting rod 11 located below the limiting arc-shaped block 8 is fixedly connected to the outer wall of the fixing column 4. A translation sliding groove 10 is provided at one end inside the dental crown 1. A driving rod 9 is movably provided inside the translation sliding groove 10. The driving rod 9 is in contact with the connecting rod 11.

[0023] As Figures 1-5 shown, a docking groove 17 is provided at the bottom of one side of the translation chute 10, and a separation groove 12 penetrating through the dental crown 1 is provided at the other side of the bottom of the translation chute 10. The docking groove 17 is located below the connecting rod 11. By providing the separation groove 12, it is convenient to install the dental crown 1. When the limiting arc-shaped block 8 is pushed to rotate so that the groove 13 is aligned with the limiting slider 7, the connecting rod 11 is aligned with the separation groove 12. When the dental crown 1 is pulled out for disassembly, the connecting rod 11 can exit the inside of the dental crown 1 through the separation groove 12.

[0024] As Figures 2-5 shown, a sealing layer 3 is fixedly arranged on the surface of the dental crown 1 by adhesion. One end of the driving rod 9 far from the fixed column 4 extends into the sealing layer 3. The sealing layer 3 is located on the side where the dental crown 1 contacts the patient's lip. The advantage of this setting is that this position is more convenient for doctors to operate with external tools. And compared with the conventional technical means, for example, in "A detachable composite artificial dental implant" with the publication number CN210204956U, where the seal is arranged on the top of the dental crown and directly bears the chewing force for a long time, this position setting can prevent the sealing layer 3 from being accidentally damaged.

[0025] As Figure 5 shown, mounting baffles 16 are fixedly connected to the top of the implant 2 and the outer wall of the fixed column 4. A torsion spring 15 is arranged on one side of the fixed column 4 between the two mounting baffles 16. The two ends of the torsion spring 15 are respectively abutted against the two mounting baffles 16. Through the resetting action of the torsion spring 15, the fixed column 4 can drive the driving rod 9 to reset after the dental crown 1 is taken out.

[0026] Working principle and usage process of the present utility model: When connecting the dental crown 1 and the implant 2, first align the connecting rod 11 with the separation groove 12, and then insert the dental crown 1 on the top of the implant 2. During this process, the movement of the dental crown 1 drives the two limit sliders 7 to contact the inclined surface structures at the top of the limit arc-shaped block 8, causing the two limit sliders 7 to move away from each other and contract into the two installation chutes 5 respectively, and squeezing the telescopic spring 6. After the dental crown 1 fits with the implant 2, the two limit sliders 7 pop out under the reset action of the telescopic spring 6, causing the two limit sliders 7 to move closer to each other and fit with the bottom of the limit arc-shaped block 8. At this time, the dental crown 1 is restricted by the two limit sliders 7 and cannot move in the vertical direction, and the shape of the dental crown 1 itself is difficult to rotate due to the restriction of the teeth on both sides during installation, thus completing the stable installation operation between the dental crown 1 and the implant 2. When the surface of the dental crown 1 is damaged, the doctor can use an external tool, for example, a dental surgical drill commonly used in oral surgery, to polish the sealing layer 3 until the sealing layer 3 is completely polished and the driving rod 9 is exposed on the surface of the dental crown 1. At this time, by pushing the driving rod 9, the driving rod 9 moves horizontally in the translation chute 10. The movement of the driving rod 9 drives the connecting rod 11 to rotate around the fixed column 4 and drives the fixed column 4 to rotate. The rotation of the fixed column 4 drives the limit arc-shaped block 8 to rotate, aligning the groove 13 with the limit slider 7 and separating from the bottom of the limit arc-shaped block 8, that is, releasing the vertical limit on the dental crown 1. At this time, the dental crown 1 can be pulled out to replace the dental crown 1, and then repeat the above operation to install the dental crown 1 through the installation mechanism.

[0027] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
