Section 8: Techniques for Use
8.1 Patient Positioning
• For optimal access to both the upper and lower arches,
the backrest of the chair should be adjusted as for other
dental procedures. This assures patient comfort and
clinician visibility.
• Have the patient turn their head to the right or left.
Also position their chin up or down depending upon
the quadrant and surface being treated. Evacuate irrigant
using either a saliva ejector or High Volume Evacuator
(HVE).
8.2 Performing Ultrasonic Scaling
Procedures
• NOTE: Refer to the Infection Control Information card
supplied with your System for general procedures to be
followed at the beginning of each day and between
patients.
• The edges of Cavitron
®
Ultrasonic Inserts are intention-
ally 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 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 handpiece. Fully seat insert
with a gentle push-twist motion. DO NOT FORCE.
• Activate the System. Hold the handpiece over a sink or
drain. Check spray temperature to verify fluid is reaching
the working end of the insert tip. Adjust the Lavage
Control knob to ensure adequate flow for the selected
Power setting. Greater flow settings provide
cooler irrigant.
• It may be necessary to adjust lavage with the System in
“Boost” mode (Foot Control fully depressed) so
adequate fluid will be available to cool tip tooth interface.
• In general, it is suggested that 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 Cavitron
®
ultrasonic insert for wear
with the DENTSPLY
®
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.
8.3 Patient Comfort Consideration
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 power setting and/or
move from the sensitive tooth to another and then
return.
Section 9: System Care
It is recommended that you perform the following maintenance
procedures to help minimize bio-film formation in the lavage
path of your Cavitron
®
SPS
™
ultrasonic scaler which could affect
the lavage flow to the ultrasonic insert tip and scaling performance.
9.1 Daily Maintenance
Start-Up Procedures at the beginning of the day:
1. Open the manual shut-off valve on the dental office water
supply system.
2. Turn the System ON using the Power ON/OFF switch. (see
illustration on page 5) Verify the Power Indicator Light is
lighted.
3. Set the Power Adjustment knob at the top of the blue scale.
4. Set the Lavage Control knob to maximum.
5. Hold the Handpiece (without an insert installed) upright over
