Abstract
Dental implant (,) for rotation into the bone tissue of a jaw bone consisting of a body having an axis of rotation, a coronal end surface (,), an apical end surface (,) and a generally cylindrical section (,) which has a coronal edge coincident with, or in close proximity to, the coronal end surface and an outer peripheral surface which extends apically towards the apical end surface from the coronal edge. The outer peripheral surface is presented by a circumferentially-oriented roughness (,) comprising a series of circumferentially-oriented peaks which are axially spaced apart by troughs and oriented at an inclined angle to the axis of rotation. The height from the troughs to the peaks throughout the circumferentially-oriented roughness is greater than 0.2 mm.
