<p>A rotary osteotome (10) for widening a dental implant site in preparation to receive a dental implant. The osteotome (16) includes a tapered body (11) tapered from a tip (15) thereof to a widened intermediate region, with at least a part of the tapered body (11) being threaded. The threads (17) 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.</p> |
