The fastening head is formed by a coronal, hollow end region of the spacer sleeve and the implant post is received in this hollow end region leaving a space for receiving an inset nut which is provided with a threaded bore extending perpendicular to the longitudinal center axis of the spacer sleeve and which is aligned with an opening in a circumferential wall of the spacer sleeve so that a securing screw can penetrate through the opening and be threaded into the threaded bore of the inset nut for securing the dental prosthesis. |
