piezoelectric ultrasonic device

pi·e·zo·e·lec·tric ul·tra·son·ic de·vice

(pē-ā'zō-ĕ-lek'trik ŭl'tră-son'ik dĕ-vīs')
An electronically powered tool that uses the rapid energy vibrations of a powered instrument tip to fracture calculus from the tooth surface and clean the environment of a periodontal pocket. This device consists of a portable electronic generator, a handpiece, and instrument inserts. The instrument tip of a piezoelectric instrument vibrates at 24,000-34,000 cycles per second.

vii) G7: medium-grit CVD tip (CR1), followed by fine-grit CVD tip (TF1, CVDentus) in a piezoelectric ultrasonic device.
For ultrasonic-gritted specimens, CVD diamond tips were adapted to a piezoelectric ultrasonic device (CVDent 1000, CVDentus), operating according to the parameters recommended by manufacturer (20 mL/min of water flow rate; 70% of its maximum power for CR1 and 50% of its maximum power for TF1).
In endodontic practice, piezoelectric ultrasonic devices have the ability to clean and shape the root canal system; remove silver points, paste, cement, and root canal filling; surgically retro-instrument and, above all, remove intraradicular metallic posts.
