Nanostructured titanium dioxide for use in bone implants: a short review

Dióxido de titânio nanoestruturado para uso em implantes ósseos: uma breve revisão

Abstract

Titanium dioxide (TiO₂) based nanostructured materials have shown great potential for use in implants thanks to their excellent physicochemical properties, such as high specific surface area, ability to elicit positive cell response, and stability in body fluids. However, there are few studies in the literature that focus on the use of nanostructured TiO₂ to support cell growth and bone regeneration. The purpose of this survey is to review the state of the art of TiO₂ for use in bone implants, as well as provide insight into its characteristics and synthesis methods. Studies of the biological properties of nanostructured TiO₂ are described, establishing its potential for the biomedical field.
