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.

Abstract

The invention provides a dental implant provided with multiple sections of threads. The dental implant comprises a dental crown and an implant, wherein the implant consists of an implant head, an implant neck and an implant root which are arranged sequentially from top to bottom; a groove is formed in the dental crown, the implant head is embedded into the groove, and the implant head is in interference fit with the groove of the dental crown; the implant root is provided with three sections of threads which are respectively a first thread section arranged at an upper part of the implant root,a second thread section arranged at a middle part of the implant root, and a third thread section arranged at a lower part of the implant root; and a tooth form depth of the first thread section is less than that of the second thread section. The dental implant provided by the invention has improved initial stability, is firmly fixed, effectively avoids the looseness of the dental implant, and reduces the stress in an alveolar bone, thereby improving the long-term stability of the implant, inducing osteoclastogenesis, promoting bone interface fusion, reducing bone resorption around the implant root, prevents bacteria from entering and being capable of widely applied to various implant denture restoration processes for hypodontia.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a dental implant provided with multiple threads. Background technique [0002] With the development of the economy and the improvement of people's living standards, patients with missing teeth have gradually increased their requirements for denture restoration, not only to meet the physiological functions, but also to have the advantages of beauty, durability, and no damage to adjacent teeth. The key to the success of dental implants lies in the compatibility and stability between the implant and the alveolar bone, which not only requires direct contact with bone tissue to form a bone structure, but also considers the mechanical fit and ability of the implant during implant placement. Whether to reasonably distribute the pressure generated during chewing to the surrounding bone tissue. Clinical experiments have found that under the action of external loads, the structur...
