Abstract
An anchoring element to be screwed into a hole made in a jaw bone comprises a threaded part with a conical portion and one or more recesses in order to form a cutting edge in each recess. Thread-turn parts starting from each cutting edge are lowered vertically at the rear where they merge with a relief arranged at a distance from each cutting edge. The relief surface is arranged on the conical portion where it extends essentially parallel to a plane tangential to the conical portion.
