رفتار سلول استخوان ساز MG-63 بر روی سطح تیتانیم اصلاح شده با محلول اسیدی

The osseointegration of oral implants is related to the early interactions between osteoblastic cells and titanium surface. Chemical surface modification of titanium (Ti) implants is used to improve peri-implant bone growth, bone-to-implant contact, and adhesion strength. Thus, in this study, the surface topography, chemistry, and biocompatibility of polished titanium surface treated with mixed solution of three acids containing hydrochloric acid (HCl)- hydrofluoric acid (HF)- phosphoric acid (H3PO4) were studied under different concentration conditions. Moreover, Osteoblast cell (MG-63) was cultured on the and treated polished titanium surface. Also, in order to investigate titanium surface, SEM, AFM and EDS analyses were carried out. The results revealed that the surface of titanium treated with mixed solution containing the aforesaid acids had higher roughness, cell attachment, and proliferation than the controls
