Embodiment 1
[0062] The present invention provides a dental implant with multiple threads, including a crown 1 and an implant; the implant consists of an implant head 2, an implant neck 3, and an implant The implant body root 4 is composed of the implant body head 2, the implant body neck 3 and the implant body root 4. The material used for the implant body is titanium alloy. The crown 1 is provided with a groove 5, the implant head 2 is embedded in the groove 5, and the implant head 2 and the groove 5 of the crown 1 are interference fit; the groove 5 of the crown 1 There is also a biological silica gel gasket 10 inside; the biological silica gel gasket 10 is located between the top surface of the implant head 2 and the top surface of the inner wall of the groove 5 . Furthermore, the implant neck 3 is covered with a nut 11 and a biosilica gel washer 9 , and the biosilica gel gasket 9 is located under the nut 11 .

Embodiment 2
[0069] The present invention provides a dental implant provided with multiple threads. The difference from Embodiment 1 is that in the first thread segment 6, the tooth profile depth is consistent, and its tooth profile depth L 1 0.4mm, pitch P between two adjacent crests 1 0.8mm, the minor diameter D of the first thread segment 6 1 =3.2mm, major diameter D 2 =D 1 +2L 1 =4.0mm, the axial height H of the first thread segment 6 1 3mm, helix angle α 1 is 4.05°, tooth profile angle β 1 is 60°.
[0070] The rest are the same as in Embodiment 1, and will not be repeated here.
Embodiment 3
[0072] The present invention provides a dental implant provided with multiple threads. The difference from Embodiment 1 is that in the first thread segment 6, the tooth profile depth is consistent, and its tooth profile depth L 1 0.37mm, pitch P between two adjacent crests 1 0.8mm, the minor diameter D of the first thread segment 6 1 =3.26mm, major diameter D 2 =D 1 +2L 1 =4.0mm, the axial height H of the first thread segment 6 1 3mm, helix angle α 1 is 4.05°, tooth profile angle β 1 is 60°.
[0073] The rest are the same as in Embodiment 1, and will not be repeated here.
