800 rpm max. Step 3 – Mark the implant axis
With the Ø 2.2 mm pilot drill, mark the implant axis by
drilling to a depth of about 6 mm.
Insert the short side of the depth gauge with the distance
indicator to check for correct implant axis orientation.
If necessary, correct unsatisfactory implant axis orientation
in the following step.
Note
The distance indicator visualizes the shoulder diameter of
4.8 mm (RN) and enables checking of the probable position
of the implant shoulder.

800 rpm max. Step 4 – Prepare the implant bed to Ø 2.2 mm
Pre-drill the implant bed to the final preparation depth
with the Ø 2.2 mm pilot drill.
Use the Ø 2.2 mm alignment pin to check the implant
axis and preparation depth.
Caution
At this point take an X-ray, particularly with vertically reduced
bone availability. The alignment pin is inserted into
the drilled area, which allows a comparative visualization
of the drill hole in relation to the anatomical structures.
5
600 rpm max. Step 5 – Widen the implant bed to Ø 2.8 mm
Continue with the implant bed preparation.
If necessary, correct the implant position with the
Ø 2.8 mm pilot drill. Use the Ø 2.8 mm depth gauge
to check the preparation depth.
For an implant with an endosteal diameter of 3.3 mm,
basic preparation ends here. Continue with the fine implant
bed preparation on page 37.
