Abstract:
1. A surgical method for expanding an initial osteotomy to receive a dental implant using continuous high-speed rotation, said method comprising the steps of: providing a rotary osteotome having a tapered working end, the working end having a plurality of longitudinally extending burnishing edges; positioning the tapered working end of the osteotome over an open end of an initial osteotomy, the initial osteotomy having an interior surface surrounded by bone and a bottom end; rotating the working end of the osteotome at high speed; enlarging the initial osteotomy by forcibly advancing the rotating working end into the initial osteotomy toward the bottom end so that the burnishing edges lap against the interior surface of the initial osteotomy without cutting into the surrounding bone to form an expanded osteotomy, the rate of said enlarging step being independent of the rate of rotation of the working end; and irrigating the initial osteotomy concurrently with said enlarging step.
