Abstract
A dental implant made of a material comprising titanium. The implant includes a head portion having a non-rotational feature, a lowermost end opposing the head portion, and a threaded bottom portion for engaging bone between the head portion implant and the lowermost end. The implant further includes a nanocrystalline surface formed on at least a portion of the implant. The nanocrystalline surface includes discrete nanocrystals deposited on a roughened surface of the implant. The roughened surface includes at least one of a grit-blasted surface or an acid-etched surface. A portion of the roughened surface is exposed between at least some of the discrete nanocrystals such that the exposed roughened portion between the discrete nanocrystals is capable of contacting bone.
