Abstract: A dynamic seal for use in a dental handpiece is disclosed. The dynamic seal includes a seal carrier including a first portion having a first feature for receiving a first compliant member and a second portion having a second feature for receiving a second compliant member, and a flange disposed between the first feature and the second feature.

Abstract: A dental insert (10) has a nozzle (30) supporting a grip sleeve (80). Nozzle 30 may include several components (31, 32, 33) that are assembled without the need for a weld. A grip retaining ring 60 is positioned at a nodal location.

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.
