Purpose: Designed to be used with 3.9 mm - 4 mm guide sleeves to prepare osteotomies for guided surgery.
Drill Sequence: Always start with the Pilot Drill (3.9 mm X 6 mm L) followed by increasing drill lengths to the final drill size for the site. The Pilot drill is recommended for starting an osteotomy on a knife-edge alveolar ridge to prevent the drill from slipping off the ridge by flattening the top surface-edge of the ridge (included in the drill set)
Flattening drills are designed to flatten the alveolar ridge when a pointed alveolar crest would deflect the initial drill off to one side or the other, buccal or lingual. Once the angled bone is flattened a round bur can be used to start the osteotomy without deflection.
