3.8 Basic safety in normal use
The active part, the handpiece is held by the practitioner throughout the treatment. Being medically qualified, the
practitioner is qualified to immediately detect any problem at the treatment site and to react accordingly.
The force applied to the handpiece fitted with its tip must be managed by the practitioner in compliance with good
dental practices. Basic safety is ensured by the practitioner.
It is advisable to have a spare medical device or an alternative means with which to perform the medical
treatment in the event of device failure.
3.9 Normal usage conditions
The normal usage conditions are as follows:
• Storage;
• Installation;
• Use;
• Maintenance;
• Disposal.
3.10 Irrigation spray
The irrigation spray is required to cool down or rinse the treatment area.
Tips must be used with the irrigation function in accordance with manufacturer recommendations.
3.11 Tip service life
The shape and weight of the tips are determined to obtain maximum performance of the ultrasonic generator.
The medical device will perform best if the user pays attention to these two characteristics. Therefore, we
strongly advise against the modification of the structure of the tips by filing, twisting or by performing other types of
modification.
In addition, tip ageing leading to normal wear can modify the tip characteristics. Systematically replace a tip that is
damaged due to wear or accidental impact (drop, distortion, etc.).
As it is not possible to establish a maximum number of uses (that may be determined by many parameters such as
duration of use, hardness of enamel, the force applied, wear, etc.), we recommend that tips being used are replaced
at least once a year.
3.12 Broken tips
A tip is a medical device to which a mechanical force is applied to perform dental treatments. The mechanical force of
the user is combined with the ultrasonic force generated by the dental handpiece.
The tips have been developed to ensure safe use in association with handpieces in accordance with the power levels
defined.
However, the tips may break depending on frequency of use, force exerted or by being dropped.
To reduce all risk, however minimal, we recommend the use of a suction device such as a saliva suction
cannula. You should also encourage your patient to breathe through their nose.
3.13 Stopping the medical device
For devices connected to the water network, shut off the dental practice's water inlet.
In the event of non-use, storage or prolonged absence, unplug the power plug from the electrical supply
system.
Before unplugging the power cord, switch the medical device to stop position O.
To unplug the power cord, take hold of it and hold the wall socket.
