Abstract
A system includes a generator with a grinder subgenerator and an ultrasonic subgenerator, a grinder handpiece, and an ultrasonic handpiece. The grinder handpiece is connected in electrical communication with the grinder subgenerator. The grinder handpiece includes a motor and a grinding tool connected mechanically to the motor. The rotational speed of the grinding tool is associated with electrical energy provided by the grinder subgenerator to the motor. The ultrasonic handpiece is connected in electrical communication with the ultrasonic subgenerator. The ultrasonic handpiece includes a transducer and a ball tip connected mechanically to the transducer. The amplitude of the vibrations at the ball tip is associated with electrical energy provide by the ultrasonic subgenerator to the transducer.
