The present invention relates to a self-tapping dental implant (10) having an outer surface provided with a circumferentially-oriented roughness, wherein the circumferentially-oriented roughness comprises first and second axial sections (19, 21), each section comprising a series of circumferentially-oriented peaks which have a crest and are axially spaced apart by throughs, wherein the axial spacing (d) between the crests of adjacent peaks in the first axial section (19) is less than the axial spacing (3d) between the crests of adjacent peaks in the second axial section (21), wherein the first and second axial sections of the circumferentially-oriented roughness are adapted in use to provide the same or substantially the same pitch.
