[0031] The working principle of the utility model is:

[0032] First, the hollow bolt 4 is tightly connected with the implant through a special thread structure, ensuring that the hollow bolt 4 is stably fixed on the implant, providing a basic support for the installation of the subsequent abutment component, then the magnetic block 11 is installed on the inner bottom of the base body 1 using a buckle structure, and then the pad plate 13 is installed at the bottom of the base body 1, so that the pad plate 13 cooperates with the magnetic block 11, then the connecting part 8 below the base body 1 is threadedly connected with the hollow bolt 4 installed on the implant, when the base body 1 is rotated, the connecting part 8 is tightly screwed with the hollow bolt 4, realizing the stable connection of the base body 1 and the implant, at the same time, the connecting rod 5 is threadedly connected into the base body 1, and the multiple sets of clamping blocks 6 at the bottom of the connecting rod 5 will be correspondingly inserted into the slot 10 and the movable slot 7 in the hollow bolt 4, completing the preliminary assembly of the internal structure;

[0034] It is worth mentioning that the base body 1, the forming part 2 and the transition part 3 are all made of medical-grade titanium alloy material, the medical-grade titanium alloy has good affinity with human tissues, greatly reduces the immune response of the human body to the implant, when the abutment is implanted into the oral cavity, it will not cause excessive inflammatory response or rejection phenomenon, creating a stable and safe microenvironment for the healing of gingival tissue, at the same time, titanium alloy has high strength, can withstand the relatively large pressure generated by daily chewing in the oral cavity, is not easy to deform or break, ensures the structural integrity of the abutment during use, the hollow bolt 4 is made of stainless steel material, which has high strength and can tightly cooperate with the base part of the medical-grade titanium alloy, ensuring that the threaded connection between the hollow bolt 4 and the connecting part 8 is stable and not easy to loosen during installation and use, in addition, the gasket 13 is made of medical-grade high polymer material polyether ether ketone, which has good compatibility with human tissues, when the gasket 13 is close to the oral tissues such as gums, it will not cause obvious immune response or inflammation, creating a safe and gentle environment for the healing of gums, which is conducive to improving the success rate of implant tooth repair, and the screw 12 is made of medical stainless steel material, which has good strength and corrosion resistance, the strength is sufficient to withstand the fastening force between the gasket 13 and the base body 1, ensuring close connection, in the oral cavity environment which is humid and rich in electrolytes, the corrosion resistance can prevent the screw 12 from rusting and corroding, ensuring long-term connection reliability and maintaining the stability of the abutment structure;

[0035] Finally, the gasket plate 13 and the base body 1 are installed with screws 12 in a symmetrical structure, which can make the gasket plate 13 and the base body 1 bear force evenly in all directions. Under the action of complex external force generated by daily activities such as chewing and swallowing in the oral cavity, the gasket plate 13 and the base body 1 will not tilt or displace due to uneven force, ensuring the stability of the overall structure of the abutment and avoiding affecting the long-term use effect of the implant. The hollow bolt 4 has a mounting groove 14 at the bottom for matching the use of the adsorption piece 9, which can accurately position the adsorption piece 9, so that its position is fixed after installation and tightly fits with the hollow bolt 4, ensuring that the adsorption piece 9 can effectively play the adsorption role when working. The top end of the connecting rod 5 penetrates the base body 1, and the base body 1 has a sliding groove matching the connecting rod 5, which can limit the movement track of the connecting rod 5, so that the connecting rod 5 moves up and down smoothly in the base body 1. When it is necessary to adjust the internal structure of the abutment or perform a specific operation, this structure can ensure the accurate movement of the connecting rod 5 and achieve the expected function. The base body 1 has a groove at the bottom for matching the use of the magnetic block 11, which can accurately position the magnetic block 11 and make it stable after installation. The magnetic block 11, the gasket plate 13 and the adsorption piece 9 all adopt a circular ring structure, which is compatible with the overall circular structure of the abutment and is more reasonable in space utilization. On the other hand, the circular ring structure can make the magnetic force or adsorption force evenly distributed in the circumferential direction. Whether it is the adsorption of the magnetic block 11 to the adsorption piece 9 or the support and isolation of the gasket plate 13 to the structure below, it can play more evenly and stably. When disassembling, first rotate the connecting rod 5 with a tool to make the clamping block 6 rotate to the lower side of the slot 10 and pull the connecting rod 5 outward, so that the clamping block 6 is separated from the movable groove 7, and then the base body 1 can be rotated and taken out from the inside of the hollow bolt 4. The whole operation process is reasonable and convenient for doctors to install and disassemble.
