Levels of calcium deposition on the implants by osteoblasts cultured in medium with fetal calf serum, FCS (measured on day 14, 21 and 28) and in serum-free medium, SF (measured on day 21 and 28). Quantification of the Calcium content was done using a modified Alizarin red method. Legend: noninfiltrated, control Ti (Ti control), titanium infiltrated with hydroxyapatite (Ti HA), Ti infiltrated with silicatitanate (Ti SiO2), cells cultivated on plastic dishes (ctrl).
