Resterilisation of reusable MD (Impactor + Instruments)
must be performed by properly trained and protected
personnel, in accordance with the applicable regulations. The
resterilisation protocol must be adapted for a risk of infection.
Before use, check that the MD (Impactor + Instruments)
and/or the osteotomes are not damaged and that no parts
are missing. Check the condition of the instruments used and
handle them with caution and care.
(The list of accessories is
included in paragraph IX)
6.1. Motor connection:
Protective gloves should preferably be used whenever the
tools are handled.
Check the condition of the MD Impactor used and handle it with due
care and attention.
The MD (Impactor) may only be connected to the motor
outside of the patient's mouth and when the motor has been
stopped.
Position the MD (Impactor) on the motor coupling (in accordance
with EN 23964 - ISO 3964) until it clicks into place. Keep the motor
and the MD (Impactor) on the same axis for this purpose.
For certain motors, it is necessary to activate the side button to
facilitate the connection.
Pull gently on the MD (Impactor) every time before use in order to
verify that it is correctly engaged on the motor coupling.
Functional test
Run the motor in the normal direction (the device will not
operate if the motor is in "reverse" mode). Check that the
MD (Impactor) properly generates regular micro-impacts.
NOTE: If you notice overheating, irregularities, vibrations or abnor-
mal sounds during operation of the MD (Impactor), immediately
contact your authorised technical service centre.
6.2. Disconnecting the motor:
CAUTION: The MD (Impactor) may only be disconnected
when the motor has been stopped, and outside of the
patient's mouth. Withdraw the MD (Impactor) while maintaining the
axis of the motor. For certain motors, it is necessary to activate the
side button to enable the MD (Impactor) to be disconnected.
NOTE: To prevent oil from leaking into the motor, do not leave the
MD (Impactor) connected to the motor if the MD (Impactor) is not
used for prolonged periods.
6.3. Connecting / disconnecting the instrument:
The instruments may only be connected to the MD
Impactor
when the motor is
switched off and outside the patient’s
mouth.

them with caution and care.
