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. The dental handpiece includes flow regions permitting steam, chemicals, and heat to flow into the inner barrel and out of the inner barrel during a sterilization technique. The dental cleaning procedure includes operating the dental handpiece and autoclaving the dental handpiece.

A dental handpiece, comprising:
- 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;
- wherein the inner barrel is rotatable relative to at least one of the coil unit and the outer sheath;
- wherein the dental handpiece includes flow regions permitting steam, chemicals, and heat to flow into the inner barrel and out of the inner barrel during a sterilization technique.
A dental handpiece, comprising:
- 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;
- and
- an outer sheath extending around at least a portion of the coil unit;
- wherein the inner barrel is rotatable relative to at least one of the coil unit and the outer sheath;
- wherein the dental handpiece is configured for adjusting torque from a lower torque level to a higher torque level by adjustment of a swivel drag adjustment screw.
A dental cleaning procedure, comprising:
- operating a dental handpiece thereby applying an alternating magnetic field to an ultrasonic insert positioned in an inner barrel of the dental handpiece, the inner barrel having a first seal at a distal end and a second seal between a proximal end and the distal end;
- and
- autoclaving the dental handpiece, allowing steam to flow through flow regions in the dental handpiece.
