9.2 Boost Mode

Boost provides a temporary increase in ultrasonic scaling power for
quick removal of tenacious calculus without touching the unit. Boost
is activated by fully depressing the Tap-On Foot Pedal to second
position (all the way to the floor). When boost is activated, the Boost
icon will illuminate on the Power Level bubble. Boost remains on as
long as the clinician has the foot pedal pressed all the way down.
In order to deactivate boost, release the Tap-On Foot Pedal to first
position.

9.3 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 his/her head to the right or left. Also position
chin up or down depending upon the quadrant and surface being
treated. Evacuate irrigant using either a saliva ejector or High
Volume Evacuator (HVE).

9.4 Performing ultrasonic Scaling Procedures

Note: Refer to the Infection Control Information booklet supplied
with your system and Section 10 of this manual for general
procedures to be followed at the beginning of each day and
between patients.
• Follow precautions listed in the General and Ultrasonic sections of
4.2 Procedural Precautions.
• The edges of Cavitron Ultrasonic Inserts are intentionally rounded
so there is minimal 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.
• Slide Power Level Control to select ultrasonic power level for
operation. Upward increases system power. Power level will
increase throughout the full range of the control. Hold the
handpiece over a sink or drain. While in Tap-On mode, simply tap
the Tap-On Foot Pedal to activate the system. (If Tap-On mode is
turned off, press and hold the Tap-On Foot Pedal down to activate
the system.) Check water spray to verify fluid is reaching the
working end of the insert tip. Adjust the water lavage control until
the water (lavage) flows with a rapid drip or small spray. Higher
water flow settings provide cooler irrigation.
• It may be necessary to adjust lavage with the system in "Boost"
mode (Tap-On Foot Pedal fully depressed) so adequate fluid will
be available to cool tip to tooth interface.
• In general, it is suggested that a "feather-light-touch" be used for
ultrasonic scaling. The motion of the activated tip and acoustic
effects of the irrigating fluid, in most cases, are adequate to
remove even the most tenacious calculus.
• Periodically check the Cavitron Ultrasonic Insert for wear with the
Cavitron Insert Wear Indicator.
• The use of a saliva ejector or High Volume Evacuator (HVE) is
recommended during all procedures.
• Set the system's Power Level Control to the lowest efficient power
setting for the application and the selected insert.
• Keep the foot pedal near your foot to make it convenient to
access.

9.5 Patient Comfort Considerations

Reasons for sensitivity
• Incorrect tip placement. The point should never be directed
toward tooth 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 excessive pressure. Use a very light grasp and pressure,
with a soft tissue fulcrum whenever possible, especially on
exposed cementum.
• If sensitivity persists, decrease power setting and/or move from
the sensitive tooth to another and then return.
SECTiON 10:

System Care

It is recommended that you perform the following maintenance
procedures.

10.1 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. Install a sterilized Steri-Mate Handpiece onto the handpiece
cable.
3. Set the Power Level Control to minimum and the Lavage
Control to maximum.
4. Turn the system ON.
5. Hold the sterilized handpiece (without insert installed) over a
sink or drain. Activate the Purge Mode by pressing the Purge
icon.
• T he Purge screen will appear indicating proper activation
of the purge function. Time icon will count down indicating
completion of purge cycle.
• T he Purge function can be interrupted at any time during
the two minute cycle by pressing the Scale icon or by
pressing the Foot Pedal.
6. After completing the purge cycle, place a sterilized 30kHz
Cavitron Ultrasonic Insert into the handpiece and set the
Power Level Control and Lavage Control to your preferred
operating position for ultrasonic scaling.
