Calibrating the burr drive
A calibration must be performed at the start of treatment as well as each time
you change or lubricate the contra-angle handpiece.
The contra-angle handpiece is automatically checked during calibration. This
includes a measurement of motor current at different speeds to assess the
properties of the system.

Setting the speed and torque
In the Implantology function, the speed and torque values of the contra-angle
handpiece, and not those of the motor, are specified. The control electronics
of the burr drive calculate the motor control based on the specified gear
reduction and the speed and torque settings.

WARNING: Only the Sirona contra-angle handpiece IMPLANT 20:1
may be used for the Implantology function.
Instruments from other manufacturers can lead to malfunctions. Outside
instruments may be improperly calibrated for implantology.
