The present invention relates to a dental implant (1, 1') having a substantially cylindrical shape with a longitudinal axis (A) defining a longitudinal direction, the dental implant (1, 1') including: a coronal section (11) including a coronal end of the dental implant (1, 1')； a threaded region (14) extending apically from the coronal section (11) to an apical tip (15) of the dental implant (1)； and an internal blind bore for connection to a secondary part, the internal blind bore including: a stabilizing section (16) which extends apically from the coronal end of the dental implant (1, 1')； and a drive and indexing section (17) which extends apically from an apical end of the stabilizing section (16), wherein the drive and indexing section (17) is provided with a plurality of connecting lobes (171) having a concave shape and extending in the longitudinal direction, the connecting lobes (171) being interconnected by respective lobe linking areas (172) also extending in the longitudinal direction, each of the lobe linking areas (172) including: two convex sections (174) extending in the longitudinal direction and adjacent to a respective connecting lobe (171)； and a concave section (175) extending in the longitudinal direction between the two convex sections (174). Further, the present invention relates to a secondary part and an insertion tool of a configuration matching the dental implant.
