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 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.
