Claim 0:
1. A dental implant with an implant extension which are formed along a longitudinal axis, the dental implant comprising:
an apical end, a coronal end and a section for receiving and securing an abutment;
the implant extension being formed in one piece with the implant and extending away from an end face of the apical end along the longitudinal axis,
the implant extension including:
a first section along the longitudinal axis with an annular constriction, which is directly connected to the end face of the apical end of the implant and is designed as a predetermined breaking point with such a small material diameter that, in the event of bending or torsion of the implant against the implant extension, the implant breaks off from the implant extension at the annular constriction, and
a second section and a splined shaft section arranged along the longitudinal axis following the first section, the second section and the splined shaft section being further away from the implant than the first section, wherein:

the second section includes therein perpendicular to the longitudinal axis an outer annular groove that is designed to be clamped in the direction of the longitudinal axis to hold the implant extension in a receptacle or a receptacle cover,
the splined shaft section is designed to be held in the receptacle or the receptacle cover to secure the implant extension against rotation around the longitudinal axis,
a coronal section of the splined shaft section includes circular segment-like first wedges extending along the longitudinal axis, the circular segment-like first wedges being formed by first hubs lying in between the circular segment-like first wedges,
an apical outer section of the splined shaft section includes second circular segment-like wedges extending along the longitudinal axis, the second circular segment-like wedges being formed by second hubs laying in between the second circular segment-like wedges, and
a second groove is formed along the longitudinal axis between the first wedges and the second wedges, the second groove being adapted for snap connection with spring arms or similar holding elements of the receptacle cover or part thereof.
