Fundamentals
Elliptical Stroke Pattern
What is the stroke pattern for magnetostrictive ultrasonic technology? (all sides are active)
Amplitude
What is the measure of how far the powered working end moves back and forth during one cycle?
Active tip area
What is the last 4 mm of a new ultrasonic insert?
Effortless rotation of insert during scaling
What is a unique feature of the Cavitron Sterimate 360 Handpiece?
1957
What is the year of the first Cavitron Ultrasonic Scaling System?
Nodal Point
What is a point or a region on a wave (insert tip) where there is no vibration?
Acoustic microstreaming
What is the enhanced effectiveness of cleaning beyond the surface actually touched by the ultrasonic tip?
Standard diameter inserts
What are inserts designed for removing moderate to heavy deposits using higher power settings?
Finger fatigue
What is larger insert grips that help to reduce finger fatigue and pinch grip?
Curved inserts
What are inserts designed to adapt/conform to curved anatomy?
Voltage
What is it that causes Piezoelectric materials to align and expand, pushing electricity to create the tip's vibration?
Frequency
What is the measure of the number of occurrences of a repeating event per unit of time (number of strokes per second)?
50% efficiency loss
What is the result of 2mm of tip wear to a magnetostrictive ultrasonic insert?
Boost mode
What is foot pedal activation to increase to a higher power when needed?

Power level
What is the ability to increase or decrease the amplitude?
Diameter and shape of the tip
What are the factors that influence the efficiency of deposit removal?
SPS Technology
Sustained Performance System - the ability of the systems to sense the need for additional power and automatically adjust to maintain stroke?
Amount of lavage
What is a factor that influences cavitation and microstreaming?
Magnetic field
What is produced when electrical energy is applied to the wire coils in a magnetostrictive handpiece?
