Introduction
The Cavitron Built-In Ultrasonic Scaling System is
equipped with a Sustained Performance System™
(SPS), which offers a constant balance between scaling
efficiency and patient comfort by maintaining the unit's
power level when the insert tip encounters tenacious
deposits allowing the clinician to effectively scale even
at a decreased/lower power setting.
The System operates by converting an SELV source
current into high frequency current. The ultrasonic
system consists of two parts: an insert and the SPS
electronic system. The SPS system incorporates two
closed loops. One loop provides automatic tuning
(operating frequency is adjusted to be at resonance for
each insert). The second loop automatically controls
the tip stroke over different working conditions. The
Cavitron Built-In Ultrasonic Scaling System produces
30,000 microscopically small strokes per second at
the insert's working tip. This, combined with acoustic
effects of the coolant water, produces a synergistic
action that literally "powers away" the heaviest calculus
deposits while providing improved operator and
patient comfort.
