Section 11: Techniques For Use
11.1 Patient Positioning
‧
For optimal access to both the upper and lower
arches, the backrest of the chair should be
adjusted to a 45° degree angle. This assures
patient comfort and clinician visibility.
‧
Have the patient turn his/her head to the right or
left. Also position the chin up or down depending
upon the quadrant and surface being treated.
Evacuate using either a saliva ejector or high
volume evacuator (HVE).
11.2 Performing Ultrasonic Scaling
Procedures
‧
Note: Refer to Section 7 and 12 for general
procedures to be followed at the beginning of
each day and between patients.
‧
The edges of ultrasonic inserts are intentionally
rounded so there is little danger of tissue
laceration with proper ultrasonic scaling
technique. Whenever the insert tip is placed in the
patient’s mouth, the lips, cheek and tongue
should be retracted to prevent accidental
prolonged contact with the activated tip.
‧
Hold the empty sterilizable sleeve of the
handpiece in an upright position. Activate the Foot
Control until fluid exits.
‧
Lubricate the rubber O-ring on the insert with
water before placing it into the sterilizable sleeve
of the handpiece. Fully seat the insert with a
gentle push-twist motion. DO NOT FORCE IT INTO
PLACE.
‧
Activate the System. Hold the sterilizable sleeve
of the handpiece over a sink or drain. Check spray
temperature to verify fluid is reaching the working
end of the insert tip. Adjust the water irrigatation
control knob to ensure adequate flow for the
selected power setting. Greater flow settings
provide cooler irrigation.
‧
It may be necessary to adjust water flow larger
under "Turbo" mode (Foot pedal fully depressed)
so adequate fluid will be available to cool tip and
tooth interface.
‧
In general, it is suggested a "feather-light-touch"
be used both supra and subgingivally. The motion
of the activated tip and acoustic effects of the
irrigating fluid, in most cases, is adequate to
remove even the most tenacious calculus.
‧
Periodically check the ultrasonic insert for wear
with the Insert Efficiency Indicator.
‧
The use of a saliva ejector or high volume
evacuator (HVE) is recommended during all
procedures.
‧
Set the system's power adjustment knob to the
lowest power setting for the application and the
selected insert.
‧
If a water leak is found in the handpiece, replace
the sleeve or o-ring on the handpiece cable
assembly to eliminate the leak.
11.3 Patient Comfort Considerations
Reasons for sensitivity
‧
Incorrect tip placement. Point should be directed
away from root surfaces.
‧
Not keeping tip in motion on tooth. Do not allow
the insert to remain in a static position on any one
area of the tooth. Change the insert's path of
motion.
‧
Applying pressure. Use extremely light grasp and
pressure, especially on exposed cementum.
‧
If sensitivity persists, decrease the power setting
and/or move from the sensitive tooth to another
and then return.
