A rotary osteotome for widening a dental implant site in preparation to receive a dental implant. The osteotome includes a tapered body tapered from a tip thereof to a widened intermediate region, with at least a part of the tapered body being threaded. The threads are feeding threads constructed to draw the tapered body into the implant site responsive to rotation thereof. A coupling provides detachable engagement with a surgical drill or hand wrench for forward and reverse rotation of the osteotome. A kit of such osteotomes includes osteotomes of gradually increasing diameters, with the diameter of the intermediate region of a first osteotome being slightly larger than the diameter of the tip for a subsequent osteotome, thereby providing for gradual widening of the implant site. |
