Abstract
A dental article coated with a friction-reducing coating and methods for coating dental articles are disclosed. In one embodiment, the dental device first is coated with an adhesion layer, followed by application of a friction-reducing coating. The friction-reducing coating is selected to create a hard, inert, friction-reducing layer on the device. The presence of the continuous outer coating of on the device reduces adhesive wear and friction on the device, and significantly improves its frictional properties.
