Abstract
The present invention describes an ultrasonic dental insert capable of enhanced operating efficiency. A first transducer generates ultrasonic vibrations. A connecting body has a proximal end and a distal end having a tip attached thereto. The proximal end is attached to the first transducer so as to receive the ultrasonic vibrations therefrom and to transmit the ultrasonic vibrations toward the tip attached to the distal end. The ultrasonic dental insert may be inserted into a handpiece for providing electromagnetic energy to the first transducer to generate the ultrasonic vibrations. The ultrasonic insert, when seated in the handpiece, is substantially decoupled, on a rotary axis, from the handpiece. A rotary force need only be applied to the insert to rotate it in the handpiece. At least one light source substantially proximate or distal to the tip may also be provided.
