Abstract
A dental prosthesis arrangement includes a lower part assigned to a jaw implant and an upper part assigned to a superstructure. The lower part engages in the upper part along a central axis. The lower part is supported against the upper part at several contact faces. The lower part and the upper part are connected releasably to each other via a securing device which provides a retaining force against axial withdrawal of the upper part from the lower part. A first radially inwardly directed structure is provided on the lower part and a second radially outwardly directed structure is provided on the upper part for receiving a holding element that provides the retaining force. A fastener passing through the upper part and connected to the lower part can alternatively fix the upper part to the lower part.
