Section 9: Techniques for Use
9.1 Patient Positioning
• The backrest of the chair should be adjusted for
optimal access to both the upper and lower arches.
This assures patient comfort and clinician visibility.
• Have the patient turn head to the right or left.
• Position chin up or down depending on the
quadrant and surface being treated.
• Evacuate irrigant using either a saliva ejector or
HVE.
9.2 Performing Ultrasonic Scaling Procedures
• The edges of Dentsply Sirona Cavitron ultrasonic
inserts are intentionally rounded so there is little
danger of tissue laceration with proper ultrasonic
scaling techniques. Whenever the insert is placed
in the mouth, lips, cheek, and tongue should be
retracted to prevent accidental prolonged contact
with the activated tip.
• Always adjust the lavage so adequate fluid will be
available to cool tip and tooth surface.
• In general, use a "feather light touch" 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.
• Set the system power adjustment knob to the
lowest power setting for the application and the
selected insert.
• Only adjust the system power adjustment knob
with the insert outside of the patient's mouth.
