Research Progress on the Biochemical Modification of Titanium Implant Surface

Abstract

Yingjie Mao and Xiaodong Li

Researchers are in constant search for the ideal implant surface condition in an attempt to improve osseointegration and to increase bone-to-implant contact. Although various techniques such as physicochemical and morphologic modification, have been proposed, they are still incapable of ensuring predictable results and guaranteed success. In recent years, investigators have also attempted to improve bone formation around implants via using biochemical modification. Various kinds of biomolecules have been introduced to endow the titanium surfaces bioactivities because of their certain bone-growth promoting capabilities. A review of the research progress is given in this paper concerning the biochemical modification of the implant surface.
