Claim 0:
1. A dental implant having a substantially cylindrical shape with a longitudinal axis defining a longitudinal direction, the dental implant including:
a coronal section including a coronal end of the dental implant;
a threaded region extending apically from the coronal section to an apical tip of the dental implant; and
an internal blind bore for connection to a secondary part, the internal blind bore including:
a stabilizing section which extends apically from the coronal end of the dental implant, and
a drive and indexing section which extends apically from an apical end of the stabilizing section,

wherein the drive and indexing section includes a plurality of connecting lobes having a concave shape and extending in the longitudinal direction, the connecting lobes being interconnected by respective lobe linking areas also extending in the longitudinal direction, each of the lobe linking areas including: two convex sections extending in the longitudinal direction and adjacent to a respective connecting lobe; and a concave section extending in the longitudinal direction and positioned between the two convex sections, and
wherein the concave section of each of the lobe linking areas is shaped so as to extend along a lateral face of a first straight cylinder having a center coincident with the longitudinal axis of the dental implant, and a diameter of the first straight cylinder is smaller than a diameter of a second straight cylinder that has: (i) a lateral face intersecting a radial outer limit of each of the connecting lobes along one line only extending in the longitudinal direction of the dental implant and (ii) a center coincident with the longitudinal axis of the dental implant.
