This Ø 4.0 mm hollow cylinder osteotome insert by Dr. Volmer and Dr. Rainer Valentin cores a cylinder of bone rather than compressing it, so an implant site can be prepared in dense bone with minimal loss of volume. The hollow design keeps the bone core inside the cylinder, where it can be retrieved for grafting. The Ø 4.0 mm size is for standard-diameter sites.
