TECHNICAL FIELD
[0001] The utility model relates to the technical field of implant, specifically is micro taper implant. BACKGROUND
[0002] In modern times, people try to use artificial materials to make various shapes of implants, which are implanted into the bone or outside the bone to repair missing teeth or provide support for tooth restoration
[0003] In order to obtain sufficient initial stability after the implant is implanted into the bone, the shape of the implant is usually designed to be a large taper, and a small pitch micro thread or groove is arranged at the neck of the implant to realize the extrusion of the cortical bone region of the neck and increase the number of thread locking with the cortical bone thread. In order to enhance the self-tapping property of the implant, a self-tapping groove is usually arranged on the outer surface of the implant. The straight self-tapping groove has strong cutting ability, but the bone chips cut down are not easy to transfer to the neck, especially when the bone quality is poor, thereby causing insufficient contact with the bone. SUMMARY

[0013] The inner side of the implant adjacent to the third outer circular cone is an inner circular cone, the side adjacent to the root portion of the inner circular cone is a hexagon, and the side adjacent to the root portion of the hexagon is an inner thread.
[0014] The diameter of the side adjacent to the neck portion of the inner circular cone is larger than that of the side away from the neck portion, and the conical angle is 12°-28°.
[0015] The hexagon and the inner thread inside the implant are used for connecting the implant and the abutment, so that the connection between the abutment and the implant is more firm, and the taper close to the neck portion can form a taper seal between the abutment and the implant, so as to prevent microorganisms from entering.
