Abstract

The ultrasonic dental scaler has a handpiece which comprises an outer shell, housing an electromechanical vibrator. The vibrator consists of a magnetostrictive transducer positioned within an energising coil located within the shell, an acoustical impedance transformer connected at one end to the transducer, and a dental work tool connected to the other end of the transformer. The transformer provides an acoustical transmission line between the transducer and the work tool. An O-ring is mounted inside the sleeve at the balance point of the transformer to form the sole support for the vibrator. The O-ring support causes the nodal plane of the vibrator to shift from its natural position to the supported position.
