Abstract
A method is provided for forming a hole in a jaw bone at a drill site. The method can comprise forming an initial hole in soft tissue of the jaw bone, advancing a first portion of the drill through the soft tissue and into a bone portion of the jaw bone to form a guidance hole in the bone portion of the jaw bone, advancing the drill until a second portion of the drill contacts the soft tissue to form an enlarged hole in the soft tissue, and further advancing the drill until the second portion of the drill contacts the bone portion of the jaw bone to form a countersink hole in the bone portion. The countersink hole can be formed to have a flat bottom that is immediately adjacent to an inclined surface thereof.
