4.  Use the Pilot Drill to shape the coronal aspect of the implant site. Drill to the depth mark. The recommended drill speed is 1200–1500rpm.

• Instruments needed:
  Pilot Drill (PD100 or DP100)

5.  Once proper alignment is verified using the Direction Indicator, proceed with the 3.25mm Twist Drill to the desired depth for implant placement in normal dense bone. Proceed with the 3.0mm Twist Drill to the desired depth for implant placement in soft Type IV Bone. The recommended drill speed is 1200–1500rpm.

• Instruments needed:
  3.25mm Twist Drill for normal dense bone
  (ITD3215, ACT3215, DT3215 or DTN3215)
  3.0mm Twist Drill for soft Type IV Bone
  (ITD315, ACT3015, DT315 or DTN315)

6.  Use the 5mm Countersink Drill to shape the coronal aspect of the osteotomy. Drill to the center of the top depth mark for subcrestal placement. The recommended drill speed is 1200–1500rpm.

• Instruments needed:
  5/6/5 Countersink Drill (CD500)

NOTE: Drilling to the center of the bottom depth mark on the CD500 will prepare the osteotomy for crestal placement and not subcrestal placement of implant.

7.  Proceed with the 4.25mm Twist Drill to the desired depth for implant placement in normal dense bone. Proceed with the 3.85mm Twist Drill for implant placement in soft Type IV Bone. The recommended drill speed is 1200–1500rpm.

• Instruments needed:
  4.25mm Twist Drill for normal dense bone
  (ITD423, DTN423, DT423 or ACT4213)
  3.85mm Twist Drill for soft Type IV Bone (ACT3815)
