Abstract:
1. A dental drill system for use in forming an osteotomy opening of a predetermined depth and diameter, and which is sized to receive a dental implant therein, said drill system comprising: at least one elongate depth drill of a first diameter adapted to drill the osteotomy opening to the predetermined depth, the at least one depth drill having a drill tip and a depth stop disposed thereon, said depth stop being spaced from the drill tip a predetermined distance that is substantially equal to the predetermined depth; and at least one elongate width increasing drill of a second greater diameter adapted to increase the diameter of the osteotomy opening to the predetermined diameter, the at least one elongate width increasing drill having a second end and an elongate body, the second end forming a substantially planar surface, a limited portion of the elongate body proximate the second end defining a tapered cutting geometry that extends in the lengthwise direction of the elongate body a predetermined distance ranging from about 0.5 mm to 1.0 mm measured from the second end, wherein the portion of the elongate body extending in the lengthwise direction from the tapered cutting geometry is adapted to for non-operative engagement with the formed surface of the osteotomy within the patient, and wherein, in use, the depth of the osteotomy is controlled by the at least one elongate depth drill of a first diameter and the substantially planar surface of the second end of the at least one elongate width increasing drill is adapted to non-abradingly seat within the formed osteotomy at the predetermined depth.
