Abstract
The invention provides a dental drill comprising a plurality of blades each distally terminating in an end cutting edge having a positive rake angle. Advantageously, this allows for efficient, accurate and safe formation of an endosseous implant-receiving osteotomy in a patient's jawbone. Desirably, any patient trauma or discomfort during the procedure is substantially eliminated or reduced and a precision-sized osteotomy for receiving an implant of a predetermined size is created.
