Abstract

A coated medical implant, such as a coated dental component, is provided, the coated medical implant including a substrate surface formed of a material comprising available hydroxyl groups and a silicon oxide coating layer chemisorbed on the substrate surface. A method for the preparation of such coated implants is also provided, the method involving application of the silicon oxide coating layer to the substrate surface by chemical vapor deposition. A dental structure is also provided, which includes a first dental component having a substrate surface formed of a material comprising available hydroxyl groups; a silicon oxide coating layer chemisorbed on the substrate surface; a silane coupling agent overlying and covalently attached to the silicon oxide layer; a dental cement overlying and coupled to the silane coupling agent; and a second dental component having a surface bonded to the dental cement.
