Figure 8.19c: Example of RPD Depth Stop Calculation with a Skull Bone Anchor
The following table helps identify the target depth range for the probe sizes available when
used with a skull bone anchor with/without Robotic Probe Driver. The depths shown assume
the bone anchor is fully threaded into the skull and the top of the bone anchor (where IGS
derived depth is measured from) is ~30mm from skull’s outer surface.
