Dental implant
2 Jan 24
A dental implant with an implant extension which are formed along a longitudinal axis: the dental implant has an apical end, a coronal end and a section for receiving; securing an abutment; the implant extension is formed in one piece with the implant; extends away from an end face of the apical end along the longitudinal axis, the implant extension having 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; the implant breaks off from the implant extension at the constriction, along the longitudinal axis following the first section, wherein the second section, splined shaft section being further away from the implant than the first section, perpendicular to the longitudinal axis, an outer annular groove being designed to hold the implant extension by clamping the groove in the direction of the longitudinal axis.
