[0008] As a preferred tent nail of the utility model, the healing cap is provided with a plurality of first through holes around it.

[0009] As a preferred tent nail of the utility model, the diameter of the right end of the connecting column is larger than the diameter of the left end, and the diameter of the left end is matched with the diameter of the screw rod.

[0010] As a preferred tent nail of the utility model, an adjusting cap is sleeved on the surface of the connecting column, the adjusting cap is movably connected to the left side of the healing cap, an arc-shaped hole for use with the connecting column is opened at the center of the adjusting cap, and the adjusting cap is made of titanium alloy.

[0011] As a preferred tent nail of the utility model, the adjusting cap is provided with a plurality of second through holes around it.

[0012] As a preferred tent nail of the utility model, the screw head, the healing cap, the connecting column, the screw rod, the mounting head and the threaded structure are all made of titanium alloy.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The screw head, healing cap, connecting column, screw rod, mounting head and threaded structure of the utility model are of an integrated design, which simplifies the surgical operation steps, reduces the complexity of component assembly, and improves surgical efficiency and convenience. The cross groove on the right side of the screw head makes it easy to tighten or loosen the screw using standard oral surgery tools, improving the versatility and convenience of operation. The first through hole on the healing cap allows soft tissue to grow in, which helps to stabilize the position of the healing cap, promote tissue healing and maintain a good blood supply, and reduce postoperative complications. The diameter of the right end of the connecting column is larger than that of the left end, which is compatible with the diameter of the screw rod. Such a design can ensure a close connection between the components, and may also help to disperse the bite force and improve the overall stability and load capacity. The mounting head can be installed in the implant through the threaded structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1-Figure 3 A tent nail includes a screw head 1, a healing cap 2 is fixedly connected to the left end of the screw head 1, a connecting column 4 is fixedly connected to the left end of the healing cap 2, a screw rod 5 is fixedly connected to the left end of the connecting column 4, a mounting head 6 is fixedly connected to the left end of the screw rod 5, and a threaded structure 7 is provided on the surface of the mounting head 6.

[0020] Furthermore, the surfaces of the screw head 1, the healing cap 2, the adjusting cap 3, the connecting column 4, the screw rod 5, the mounting head 6 and the threaded structure 7 are all coated with an antibacterial coating.

[0021] Furthermore, a cross slot 8 is provided on the right side of the screw head 1 .

[0022] Furthermore, a plurality of first through holes 9 are formed around the healing cap 2 .

[0023] Furthermore, the diameter of the right end of the connecting column 4 is larger than the diameter of the left end, and the diameter of the left end is matched with the diameter of the screw rod 5 .

[0024] The screw head 1, the healing cap 2, the connecting column 4, the screw rod 5, the mounting head 6 and the threaded structure 7 are designed as an integrated whole, which simplifies the surgical operation steps, reduces the complexity of component assembly, and improves the surgical efficiency and convenience.

[0025] The cross groove 8 on the right side of the screw head 1 allows the screw to be easily tightened or loosened using standard oral surgery tools, thereby improving the versatility and convenience of operation. The first through hole 9 opened on the healing cap 2 allows soft tissue to grow in, helps to stabilize the position of the healing cap 2, promote tissue healing and maintain a good blood supply, and reduce postoperative complications.

[0026] The diameter of the right end of the connecting column 4 is larger than that of the left end, and is compatible with the diameter of the screw rod 5. Such a design can ensure a tight connection between the components, and may also help to disperse the bite force, improve the overall stability and load capacity, and the mounting head 6 can be installed in the implant through the threaded structure 7.

[0027] Furthermore, an adjusting cap 3 is sleeved on the surface of the connecting column 4 , and the adjusting cap 3 is movably connected to the left side of the healing cap 2 . An arc-shaped hole 10 for use with the connecting column 4 is opened at the center of the adjusting cap 3 .

[0028] Furthermore, a plurality of second through holes 11 are formed around the adjusting cap 3 .

[0029] By sleeved the adjusting cap 3 on the surface of the connecting column 4, the healing cap 2 can be increased. The correct height can better guide the healing of the gingival tissue, avoid gingival recession caused by too high or soft tissue hyperplasia caused by too low, thereby promoting the healing quality and creating a good biological basis for subsequent repair. The arc hole 10 on the adjusting cap 3 is adapted to the surface of the connecting column 4 to facilitate their close assembly. The second through hole 11 on the adjusting cap 3 corresponds to the first through hole 9, and the first through hole 9 and the arc hole 10 also play a role in weight reduction.

[0030] Furthermore, the adjusting cap 3 is made of titanium alloy, and the screw head 1, the healing cap 2, the connecting column 4, the screw rod 5, the mounting head 6 and the threaded structure 7 are all made of titanium alloy.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
