Zygomatic-penetrating implant and oral implant

Abstract

The invention relates to the technical field of dental implantation, in particular to a zygomatic-penetrating implant and an oral implant. The zygomatic-penetrating implant comprises an implant head part, an implant transition part and an implant neck part which are connected in sequence, the implant head part is a conical body, the outer diameter of the implant head part is gradually increased from the near end to the far end, the implant head sequentially comprises a guide part and a mounting part from the near end to the far end, the surface of the guide part is a smooth surface, the near end of the guide part is a spherical surface, the far end of the mounting part is connected to the implant transition part, a plurality of threaded sections are sequentially arranged on the periphery of the mounting part, and a self-tapping groove is formed in the mounting part. In the application, the guide part is a small-diameter smooth guide area and has no threaded surface, so that inflammatory reactions such as skin buccal fistula and the like caused by the guide part are avoided. The implant transition part is a smooth surface, so that irritant trauma of the maxillary sinus membrane is avoided. The implant neck part is a thread-free and low-roughness surface, so that biological complications of the implant neck part are reduced while osseointegration is facilitated.

Description

technical field [0001] The present application relates to the technical field of dental implants, in particular to a zygomatic implant and an oral implant. Background technique [0002] Transzygomatic implant surgery is a dental implant restoration method used when patients with severe maxillary bone loss or atrophy are unwilling to undergo bone augmentation surgery such as bone grafting and bone distraction, and expect dental implant restoration. Transzygomatic implant surgery refers to the implantation of dental implants into the zygomatic bone. With the help of the dense bone block of the zygomatic bone, 2 to 4 conventional dental implants are placed in the anterior tooth area to jointly complete the restoration of the maxillary dentition. The length of the transzygomatic implant is generally 30.0-52.5mm. Transzygomatic implants enter the maxillary sinus from the alveolar ridge, enter the zygomatic bone through the outer mucosa of the maxillary sinus or the outer bone wa...

AI Technical Summary

Problems solved by technology

At present, the zygomatic implants used in the market are basically threaded throughout the entire process, and the surface of the implant is roughened. Once the thread of the implant neck part is leaked, the surface of the exposed implant thread is not easy to clean, which can easily lead to peri-implantitis. Resulting in the failure of zygomatic implant restoration
