Abstract
A dental handpiece and a dental cleaning procedure are disclosed. The dental handpiece includes an inner barrel for rotatably retaining an ultrasonic insert, the inner barrel configured for contacting the ultrasonic insert with a cooling fluid in the inner barrel, a coil unit arranged and disposed to apply an alternating magnetic field to the ultrasonic insert when positioned in the inner barrel, an outer sheath extending around at least a portion of the coil unit, and the inner barrel is rotatable relative to at least one of the coil unit and the outer sheath. The dental cleaning procedure includes operating the dental handpiece and autoclaving the dental handpiece, allowing steam to flow through flow regions in the dental handpiece.
