Implant that can be implanted in osseous tissue, method for producing said implant and corresponding implant

A bone implant suitable for implantation in an implantation direction parallel to an implant axis in a cavity surrounded by a cavity wall of bone tissue comprising an implant portion, wherein the implant portion to be implanted comprises exterior surface ranges formed by pressing liquefiable material out of a hollow space in the implant through openings that extend through the implant portion, and wherein the implant portion further comprises energy directors at an inlet to the openings to direct liquefied material into the openings and chip forming cutting edges being disposed on an exterior of the implant portion and being capable of cutting the cavity wall of bone tissue, said cutting edges not extending in a common plane with the implant axis, said cutting edges facing toward a distal end region of the implant and extending at least partly around the circumference of the implant, wherein said cutting edges comprise a wedge angle β between a proximal and a distal cutting edge surface of less than 90°, a clearance angle α between the proximal edge surface and a cylindrical surface rotated around the implant axis with a sum of a plus β being smaller than 90°, and an angle Υ between the distal cutting edge surface and the implant axis of 90° or less and wherein said cutting edges are distanced from the implant axis by implant-axis-to-cutting-edge-distances, which implant-axis-to-cutting-edge-distances are decreasing in the implanting direction.

A bone implant shaped to be implanted without substantial rotation in an implantation direction parallel to an implant axis into a cavity in bone tissue wherein an implant portion to be implanted comprises:

• an interior surface defining an energy director, said energy director being at an inlet to an opening extending through said implant portion;
• cutting edges and exterior surface ranges of a material which is liquefiable by mechanical vibration,
• and wherein said cutting edges:
• are not extending in a common plane with the implant axis,
• are chip forming cutting edges capable of cutting a cavity wall of bone tissue,
• are facing toward a distal end region of the implant and are extending at least partly around the circumference of the implant,
• wherein said exterior surface ranges are formed by pressing the liquefiable material out of a hollow space in the implant and through the opening to the outer surface of the implant.
