INTRODuCTION
WARNING: Breakage and wear-out of
the inserts. High frequency oscillations and
wear-out may, in rare circumstances, lead to
the breakage of the insert.
Deformed or otherwise damaged inserts are
susceptible to breakage during their use.
These inserts must never be used.
Should an insert fracture, during use, check
that none of its fragments remain in the
treated part and, at the same time, apply
effective suction to remove them.
The patient must be instructed to breathe
through his nose during the treatment, or
a dental dam must be used to prevent the
patient from ingesting fragments of broken
inserts.
Check the state of wear of the insert and
its integrity before and during each use.
If a drop in performance occurs, see to its
replacement.
The state of wear of the most common
inserts (S1, S1-S, S2, S5, P2, P4, P10) can be
checked using the supplied INSERT-CARD. To
use the INSERT-CARD correctly:
• Position the insert on the INSERT-CARD
so that the profile corresponds to the
one printed on the card. The printed
profile on the card has a red line
indicating the limit of wear;
• If the insert is shorter than the limit of
wear, its performance will be significantly
inferior compared to that of a new insert,
and should therefore be replaced.
If the layer of titanium nitride (gold-plated
surface), where present, is visibly worn, the
insert must be replaced. The use of a worn
insert reduces its efficiency.
When the nitride coating wears out, the
efficiency decreases; re-sharpening the insert
damages it and is therefore forbidden. Check
that the insert is not worn out. During the
intervention, frequently check that the insert
is intact, especially in its apical part.
During the intervention, avoid prolonged
contact with retractors or with metallic
instrumentation in use. Do not exert excessive
pressure on the inserts during their use.
NOTE: In case of accident attributable to the
device during correct use and in accordance
with the intended use, a report must be
made to the Competent Authority and
manufacturer indicated on the product label.
