Abstract
An ultrasonic insert carries a rotary bearing adjacent to the transducer. The bearing slidably engages an ultrasonic handpiece. When seated in the handpiece, the insert 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. Alternately, an adaptor can be inserted into the handpiece. The adaptor slidably receives a conventional ultrasonic insert. The conventional insert can be easily rotated with a force applied only thereto, relative to the handpiece.
