| Abstract |
Nanostructured titanium (nTi) with essential enhanced strength and fatigue characteristics is an
advanced material for dental implant applications. Nano Ti is commercially pure titanium, that was
nanostructured by a special technique of severe plastic deformation. It is bio inert, does not contain
even potentially toxic or allergenetic additives and has significantly higher specific strength
properties than any other titanium applied in dental implants. Cylindrical threaded screw implants
Nanoimplant® sized 2.4 mm in diameter and 12 mm in length were made from nTi. It is the first
application of nTi dental implant in the world reported. Recently more than 250 successful clinical
applications dealing with surgery on the front teeth were carried out. No complications were
noticed during the early postoperative period and early loading. Laboratory cytocompatibility tests
undertaken so far on mice fibroblast cells have indicated that nanocrystalline Ti surface has a
significantly better property for cell colonisation and healing of tissue consequently. |
