Abstract:

Objective The aim of this article is to study on the nano-scale materials in the role of implant osseointegration. Methods In this study, nano-scale titanium films were prepared by direct magnetron sputtering on titanium implants. Then the prepared implants coating with the nano-scale thin film are implanted in the bones of animals. The study of the early integration of the bone will be done between the experimented and control groups. Results Analyzed superficial configuration by magnetron sputtering, it showed that nano-scale granular diaphragm formed and it was homogeneous and compact. Dimension of nano-scale granular on lamellar implants was similar with that on columnar implants. However, nano-scale granular was more homogeneous in lamellar ones. The result of animal experiment showed that initial osseointegration increased after implant surgery utilized implants coating by nano-scale titanium thin film. Conclusion Serial animal experimentation manifested that bioactive can be improved after nano-scale titanium thin film formed on the surface of materials.

Key words: titanium implant, magnetron sputtering, surface modification, nanostructure, animal experimentation
