ABSTRACT:
A sonic delivery system for dentistry. The sonic delivery system includes a hand piece housing an exciting energy source connected to a driver rod which is further releasably engaged with an energy transfer tip. The driver rod linearly extends and contracts in response to the exciting energy source producing a reciprocating linear movement of the driver and energy transfer tip. In one embodiment, a rotary coupler is connected to the driver to convert the reciprocating linear movement of the driver into rotary movement of the energy transfer tip. Preferably the exciting energy source is alternating current and the driver is a rod constructed of terfnol material.
