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.
 
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.
