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.
Claims9
A sonic delivery system for use in the treatment of tooth structures, said system comprising:
- a handpiece configured to house an exciting energy source and shaped for hand use;
- a driver coupled to said housing and engaged with said exciting energy source, said driver adapted to linearly extend and contract responsively to said exciting energy source for producing reciprocating linear movement in at least a portion of said driver and said driver being a rod comprising terfnol;
- and
- an energy transfer tip releaseably coupled to said driver, said energy transfer tip adapted for contact upon a tooth structure.
