Claims11
A method for forming an anti-microbial layer on an apparatus, comprising:
- (a) forming a titanium (Ti) vapor that solidifies to form a titanium (Ti) layer on the apparatus;
- (b) forming a titanium-nitride (TiN) vapor that coats the titanium (Ti) layer with a titanium-nitride (TiN) layer;
- and
- (c) reacting the titanium-nitride (TiN) layer with an allyl halide or an alkenyl halide to quaternize the titanium-nitride (TiN) to form a quaternized the titanium-nitride (TiN) wherein the apparatus is selected from the group consisting of a dental implant, a crown, a bridge, a filling, a veneer, an inlay, an onlay, an endodontic device, and an orthodontic bracket.
