Here are four things to know.
1. When considering implant material, titanium is especially conducive to osseointegration. While it was once thought that the titanium surface becomes nonreactive when it oxidizes in the body, recent data suggests that a chemical reaction between oxidized titanium and calcium phosphate is possible. This reaction is responsible for osseointegration.
2. Osseointegration can be enhanced by altering roughness or coating titanium with a ceramic such as hydroxyapatite. Research suggests, however, that the nanosurface of the implant is more important than the material’s crystal structure and other surface pretreatments.
3. Tensile strain transmitted to an osteoblast adhering to the surface of an implant can promote the production of bone morphogenetic protein.
4. Interbody implants are being designed with the principles of nanosurface technology in mind.
