Increased Pre-Osteoblast Bioactivity on Ca-Modified Titanium

Abstract:

The aim of this study is to evaluate a new and simple titanium surface modification by calcium treatment. The treatment was carried out by immersing titanium in CaCl₂ solution at 80°C which consider mild temperature. The XPS spectra showed that calcium has been successfully immobilized onto titanium surface. Moreover, the thickness of oxide layer increased after the treatment due to exposure of titanium surface to aqueous solution. In vitro evaluation revealed that the calcium treated titanium shows higher osteconductivity including greater cell attachment and proliferation. The results suggested that our current titanium surface modification is promising to improve osteoconductivity.
