The true ultrasonic hand piece operates on a wave length. They are used with similar tools and abrasives as a profiler. Because ultrasonics vibrate in a 4 to 30 micron range, their use is limited to small areas and intricate detail. They are very efficient when used properly. Tool length is critical for proper operation. Ultrasonic hand pieces are available in electric and air drive. However, it should be noted that the air drive is not a true ultrasonic tool.
