1. 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;
controlling a rotational speed of the non-round or non-circular drill bit such that a hard bone enters a cutting zone of the non-round or non-circular drill bit while the soft bone remains in a no-cutting zone of the non-round or non-circular drill bit while a cutting edge positioned within the cutting zone passes by the hard bone, wherein the cutting zone and the no-cutting zone are positioned in the same cross-sectional plane perpendicular to a 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 within an acceptable range;
stopping the drilling of the non-round or non-circular drill bit; and
implanting an implant into the hole.
