Claim 12:
13. A method of preparing an osteotomy, the method comprising:
drilling a hole in a jaw bone with a non-round or non-circular drill bit, wherein a cutting edge of the non-round or non-circular drill bit is at a first radial distance from a longitudinal axis of the non-round or non-circular drill bit, wherein a maximum outer radius of the non-round or non-circular drill bit is at a second radial distance from the longitudinal axis, wherein the second radial distance is larger than the first radial distance, wherein the cutting edge and a no-cutting zone are positioned in the same cross-sectional plane perpendicular to the longitudinal axis of the non-round or non-circular drill bit;
measuring an insertion torque of the non-round or non-circular drill bit;
determining the insertion torque is not within the acceptable range; and
drilling with a second drill bit to modify the hole.
