an oral implant

Abstract

The invention discloses an oral implant. The oral implant comprises an outer shell body and an implantation hole arranged inside the outer shell body, the outer shell body comprises a cylindrical mainbody part with an external thread, a circular truncated cone-shaped inclined shoulder part arranged on the top of the main body part, and a hemispherical spherical bottom part disposed at the bottomof the main body part. A first thread region and a second thread region are disposed on the main body part from the top to the bottom, and the pitch of the first thread region is smaller than the pitch of the second thread region. The implantation hole includes a tapered hole and an internal hexagonal hole, the tapered hole is arranged downward from the top end of the inclined shoulder part, the internal hexagonal hole is arranged at the bottom of the tapered hole, the cross-section of the internal hexagonal hole is internal hexagonal, and the maximum diameter of the inner hexagonal hole is smaller than the smallest diameter of the tapered hole. The oral implant has good initial stability and high planting success rate, and bacterial sealing of the implant and a base is good, the connection is more stable.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an oral implant. Background technique [0002] Dental implants are surgically implanted into the upper and lower jaws of the missing teeth of the human body. After the surgical wound is healed, a device for repairing dentures is installed on its upper part. The core of dental implants lies in the implant part, which is equivalent to the root of the real tooth and plays a vital role in the fixation of the entire tooth. [0003] Currently, there are three common forms of implants: [0004] First, the connection between the abutment and the implant is a screw-retained implant (similar to the Nobel implant). Such screw-retained implants cannot achieve a complete bacterial seal, and the central screw may frizz or break when subjected to lateral force due to excessive force. It is not advisable to place the implant too deep during the planting process, because there is a h...

AI Technical Summary

Problems solved by technology

This type of implant is the same as the first type of implant. The implant with screw retention cannot achieve complete bacterial sealing, and when subjected to lateral force, the central screw will appear frizzy or broken due to excessive force

[0007] To sum up, the existing implants have the problems of poor initial stability, poor bacterial sealing of the threaded connection between the implant and the abutment, and the problems that the screws are easy to frizz or break
