Embodiment 1:

[0019] As Figures 1-4The utility model provides a strong stability's dental implant, including implant module 1 and abutment module 2, implant module 1 includes implant main part 101, the top of implant main part 101 is provided with implant neck ring 102, the outer surface of implant main part 101 is provided with double gradient thread 103, the bottom of implant main part 101 is provided with cutting groove 105, the inner surface of cutting groove 105 is provided with degradable lubricating layer 106, the inside of implant main part 101 is provided with conical groove 107, the outer surface of implant neck ring 102 and double gradient thread 103 all is provided with micro recess 104, the inner surface of micro recess 104 is provided with bioactive coating 108, abutment module 2 includes abutment support part 201, the bottom of abutment support part 201 is provided with conical part 202, the bottom of conical part 202 is provided with threaded mounting part 203, the outer surface of threaded mounting part 203 is connected with connecting part 204 in screw thread.

[0020] Specifically, the degradable lubricating layer 106 is made of polyether ether ketone material.

[0021] Specifically, the inner surface of the conical groove 107 is matched with the outer surface of the conical part 202.

[0022] Specifically, the bioactive coating 108 is made of hydroxyapatite coating.

[0023] Specifically, the micro recess 104 is provided with a plurality of holes, the aperture of the micro recess 104 is 10-50 microns, and the depth of the micro recess 104 is 5-20 microns.

[0024] The working principle and beneficial effects of the above embodiments.

[0025] In use, the double-tapered thread 103 adopts a hook thread design, one at the thread root and one at the thread tooth, forming a double taper, increasing the contact area between the implant and the bone tissue, improving the stability of the implant in the early stage of implantation, enabling the implant to fuse with the bone tissue faster, helping to disperse the masticatory force and reduce the local pressure on the implant, even in poor bone conditions, to maintain good retention and ensure the success rate of the operation. The design of the double-tapered thread 103 enables the dental implant to adapt to various bone conditions, whether it is an incisor implant in the maxilla or mandible, or a complex case of edentulous jaw implantation, alveolar bone atrophy, cancellous bone, etc. It can significantly improve the success rate of immediate implantation to 80%. The cutting groove 105 can collect bone debris generated during the drilling process of the dental drill, maximizing the use of autologous bone. The degradable lubricating layer 106 covers the inner surface of the cutting groove 105, reducing frictional resistance during implantation and reducing surgical torque. It can gradually degrade after the operation, and the 1mm implant neck ring 102 effectively reduces the micromotion of the implant during the initial loading, reducing the risk of postoperative complications. In addition, the 1mm thickness of the neck ring is precisely calculated to ensure the strength of the structure while avoiding excessive occupation of the alveolar bone space, ensuring the long-term stability of the implant after implantation. The bioactive coating 108 is coated on the microgroove 104 of the implant neck ring 102 and the thread surface, providing a bone induction interface to accelerate bone cell attachment and differentiation and shorten the bone integration period. In summary, the dental implant realizes the following functions: during the implantation stage, the degradable lubricating layer 106 assists the implant in rotating quickly, reducing bone damage; in the early postoperative period, the double-tapered thread 103 provides mechanical stability, and the hydroxyapatite coating initiates bone integration; and in long-term use, the tapered connection structure formed by the tapered part 202 and the tapered groove 107 disperses the occlusal force, improving the durability of the system.
