Claim:
A device for forming a bone bed for a dental implant, comprising a bone bed forming element wherein a bone bed surface is formed by the bone bed forming element is congruent to an outside surface of the implant, without gaps between the formed bone bed surface and the implant, to allow for osteointegration of the implant into bone tissue, said forming element having a tail part for engagement with a rotatable drive, a connecting neck, and a head with cutting elements formed as a rotatable plate, said head being composed of a crystal of partially stabilized zirconium dioxide with a nanostructure and a crystallographic axis coinciding with an axis of said forming element, said plate having two broad facets, each facet with a vertical profile formed by at least two arcs that are convex relative to said axis of said forming element, with an entire transition from one of said convex arcs to another of said convex arcs being smoothed by arcs that are concave relative to said axis of said forming element, with grooves provided only along said convex arcs on opposite sides of each of said broad facets and forming with narrow facets of said plate a first group and a second group of cutting elements.
