Abstract:
1. A method for producing a surface structure on a dental implant, the method comprising: cooperating parts of a tool with a blank which is intended to form the dental implant; assigning controls which give rise to mutual displacements between the parts and the blank so that the parts follow a substantially spiral trajectory along a surface of the blank; and forming a thread on the surface of the blank, the thread when seen in side view comprising an outer surface and a wave pattern with at least one trough disposed on the outer surface of the thread, the trough extending in a course that substantially follows a spiral trajectory of the thread, the wave pattern when seen in side view extending along the outer surface of the thread in a generally longitudinal direction of the implant, wherein the trough depth is in the range of between approximately 25 to 200 μm.
