A three part ultrasonic dental insert (10), and replacement system (12, 14, 16) used in a handpiece (70) having an induction coil (74) disposed about a well (80), and operably connected to a power supply. The three parts include a magnetostriction element (12), a velocity transducer (14), and a tip (16). The magnetostriction element (12) has a crown (22) at one end which is releasably attached to a proximal end of the velocity transducer (14). The tip (16) is releasably attached to a proximal end of the velocity transducer (14). The insert (10) can comprise a set of interchangeable tips (16) wherein the velocity transducer (14), and the tips (16) are ultrasonically operable with the coil (74), and the magnetostriction element (12). The three part replacement system (12, 14, 16) comprises a set of magnetostriction coils (12), and a set of the velocity transducer elements (14), as well as the interchangeable tips (16). The velocity transducer (14), and tip (16) sets include a plurality of transducer tip combinations (14, 16) operable at the ultrasonic frequencies of the magnetostriction elements (12). |
