1. A method of forming a nanocrystalline surface on an implant, the method comprising the acts of:
- roughening at least a portion of the implant surface to form a roughened surface;
without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface, the nanocrystals comprising a material having a property that promotes osseointegration.

Abstract
A method of forming a nanocrystalline surface on an implant is disclosed. The method comprises the act of roughening at least a portion of the implant surface to form a roughened surface. The method further comprises the act of, without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface. The nanocrystals comprise a material having a property that promotes osseointegration.

18. A dental implant comprising:
-
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 and the lowermost end, the threaded bottom portion having a roughened surface with a substantially uniform array of microscale irregularities having peak-to-valley heights not greater than about 20 microns, the threaded bottom portion further including discrete nanoparticles located on the roughened surface, the nanoparticles including hydroxyapatite nanocrystals. - View Dependent Claims (19, 20, 21, 22)

23. A method of forming a nanocrystalline surface on an implant, the method comprising the acts of:
-
providing a metal substrate;
immersing at least a portion of the substrate in a colloidal solution having a temperature ranging from about 18°
C. to about 32°
C. for about 11.5 minutes to about 240 minutes, the colloidal solution comprising;
a 2-methoxyethanol solvent, and a plurality of hydroxyapatite nanocrystals having a concentration ranging from about 0.01 weight percent to about 1 weight percent relative to the overall solution; and
adjusting the pH of the colloidal solution to about 9 to about 11.
