  • Multiple layer coating and coating method for dental devices and the like
    Patent number: 10195004
    Abstract: A multi-layer coating of alternating titanium nitride (TiN) and titanium carbo nitride (TiCN) layers is applied to at least part of a dental device for use in attaching crowns, overdentures, and the like in a patient's jaw, where the outermost layer is TiCN with a predetermined percentage of carbon to produce a pink color. The pink outermost layer is of sufficient thickness to conceal the color of the underlying layers, and is very hard and resistant to wear and damage in use. At the same time, the outermost TiCN layer is of a color consistent with the gingival anatomy, and is very hard and resistant to wear and damage in use.
