Abstract: A device for forming a bone bed for dental implants having a head composed of crystal of partially stabilized zirconium dioxide with a nanostructure having a crystallographic axis that coincides with the axis of the bone bed forming device. The head has cutting elements formed as a rotatable plate. The plate has two broad facets formed by circular arcs that are convex relative to the axis of bone bed forming device. Transition from one of the convex circular arc to another convex circular arc is smoothed by circular arcs that are concave relative to the axis of bone bed forming device. Grooves form first and second cutting members with narrow facets of the plate. The head has an end part shaped as a truncated sphere possessing a recess formed by two planes arranged at an angle of 90° relative to each other and passing through the truncated sphere center and two points belonging to two diagonally arranged plate ribs.
