4.5 Important information on the Inserts
WARNING :
• Before using the sterilised insert, check
the integrity of the sterile packaging
and inspect the product to ensure there
is no damage. The insert will no longer
be sterile if the packaging is broken or
damaged. If the packaging is damaged,
the insert MUST be sterilised again
before use.
• Before starting to work, properly tighten
the insert to the handpiece using the
torque wrench.
• When the layer of titanium nitride is
visibly consumed the insert must be
replaced. The use of an insert too worn
decreases its efficiency.
• Diamond Inserts: diamond inserts must
be replaced when the layer of titanium
nitride is visibly worn and in any case
after a maximum of 10 treatments.
• Do not activate the handpiece while the
insert is in contact with the part to be
treated so that the electronic circuit can
recognise the best point of resonance
of the insert allowing optimum
performance.
• Check the state of wear of the insert and
its integrity before and during each use.
If you experience a loss of performance
provide for its replacement.
• Use only original Mectron inserts. The
use of non-original inserts will void the
warranty and damage the thread of the
multipiezo handpiece, with the risk of
no longer being able to correctly screw
in the original inserts for subsequent
use. In addition, the machine settings
are tested and guaranteed for correct
operation using only original Mectron
inserts.
• Do not change in any way the shape of
the insert, by bending it or filing it. This
could cause it to break.
• Do not use an insert that has undergone
deformation of any type.
• Do not attempt to sharpen an insert
used.
• Always check that the threaded parts
of the insert and the handpiece are
perfectly clean - See Chapter 6 on page
19 - Cleaning and sterilisation.
• Excessive pressure applied to the insert
can cause it to break and potentially
injure the patient.
• The Mectron inserts vibrate with
longitudinal oscillation, with a back
and forward movement. During the
treatment, always keep the instrument
in a tangential direction with respect
to the surface of the tooth. Move the
handpiece back and forward, applying
slight side pressure.
• Do not point the instrument directly
onto the surface of the enamel or
implant. Position the tip/operating
part only in a tangential direction with
respect to the surface of the tooth or
implant.
• The insert must be held in constant
movement. If the insert is blocked it may
cause overheating of the treated part.
It is recommended to use continuous
motions to minimise contact between
the tip and the part. Do not block them
against the tissues so as not to cause
their overheating. It is advisable to
increase the level of irrigation as the
power level increases.
• Leave the ultrasonic vibrations to work,
do not exert excessive pressure on the
inserts during use. Apply slight force on
the insert for optimum performance.
• When the insert is used in interproximal
spaces, do not block the instrument
or leverage on the operating part. The
inserts must be left free to vibrate.
