Enossales Einzelzahnimplantat mit Verdrehsicherung

摘要

The invention concerns an endosseus single-tooth implant for a fixed dental prosthesis, the implant comprising: a substantially cylindrical basic body which can be inserted into a bore in a jaw bone and has a blind hole open towards the coronal end thereof; a spacer sleeve which can be placed on the coronal front edge of the basic body; an implant post which can be inserted into the blind hole in the basic body and connected thereto and penetrates an internal bore in the spacer sleeve; a connection device for securing the spacer sleeve on the basic body such that said sleeve cannot rotate; and a securing head for the dental prosthesis. The implant is characterized in that the securing head is formed by a coronal hollow end region of the spacer sleeve; the coronal end of the implant post is disposed cervically below the end region; and, in order to secure the dental prosthesis, a securing screw, which penetrates an opening in the peripheral wall of the end region, can be screwed into an insert nut which is provided with a threaded bore extending perpendicular to the longitudinal centre axis of the spacer sleeve and is disposed in the end region.
