ABSTRACT:
A dental drill system for use in preparing an osteotomy of a predetermined depth and diameter sized to receive a dental implant therein is disclosed. The drill system comprises at least one elongate depth drill of a first diameter adapted to drill the osteotomy opening to the predetermined depth, and at least one elongate width increasing drill of a second greater diameter adapted to size the diameter of the osteotomy opening to the predetermined diameter. The invention also teaches a method of using the dental drill system to form the osteotomy opening, the method comprising the steps of using a starter drill to define at least a portion of the osteotomy opening, using at least one elongate depth drill of a first diameter to drill the osteotomy opening to the predetermined depth, and using at least one elongate width increasing drill of a second greater diameter greater than the first diameter to increase the diameter of the osteotomy opening to the predetermined diameter.
