This trephine with an inside diameter of 8.0 mm cores a cylinder of bone: it is used to harvest a bone core for grafting, to remove a failed implant with minimal bone loss, or to take a biopsy. The fixation support (guide pin) centers the trephine on a pilot hole so the core is cut exactly where planned. It has 9 teeth on a 2.35 mm shank and is one of the larger sizes, for wide implants and block harvesting.
