Abstract:
1. A low-impact surgical method for expanding an osteotomy using 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 osteotomy, the osteotomy having an interior surface surrounded by bone; rotating the working end of the osteotome at high speed; and enlarging the osteotomy by axially bouncing the rotating working end within the osteotomy so that the burnishing edges lap against the bone interior surface with downward motion and separate from the interior surface with upward motion in ever deepening movements that cause a progressive plastic deformation of the bone interior surface beginning adjacent the open end and developing downwardly into the osteotomy.
