Referring to fig. 8, the dental implant region is cut with the bone pieces 20 along the horizontal direction of the interface of the implant head 100 and the implant end 200, and then the implant end 200 is lifted by rotating the adjusting screw 300, and the implant end 200 can drive the bone pieces 20 to be separated from the jawbone 10 due to the coupling of the bone pieces 20 and the implant end 200, thereby forming the long bone space 30 between the bone pieces 20 and the jawbone 10. The rotation of the adjusting screw 300 is continued until the ground contour of the bone piece 20 matches the outer contour of the jaw 10, and if the height of the bone piece 20 exceeds the outer contour of the jaw 10, still without matching the outer contour of the jaw 10, the bone piece 20 is ground again until the bone piece 20 contour completely matches the outer contour of the jaw 10.
Then, the gingiva is sutured after the long bone space 30 is filled with the biological material and the membrane, the biological material and the membrane can promote the natural regeneration of the jawbone 10, the bone block 20 is fused with the jawbone 10 rapidly, the growing bone wraps the implant end 200, the implant end 200 is combined with the jawbone 10 repaired by a patient more tightly, and meanwhile, the telescopic implant can be provided with a base station and other accessories of the implant, and further, the implant implantation operation and the jawbone quantity repair operation can be completed simultaneously, so that the whole dental implant operation period is shortened greatly.
While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
