  • Title: Short-term plasma-cleaning treatments enhance in vitro osteoblast attachment to titanium.
    Author: Swart KM, Keller JC, Wightman JP, Draughn RA, Stanford CM, Michaels CM.
    Journal: J Oral Implantol; 1992; 18(2):130-7. PubMed ID: 1289550.
    Abstract:
    The purpose of this research was to characterize the in vitro cellular behavior of osteoblast-like cells on titanium surfaces prepared with argon plasma-cleaning (PC) treatments for various lengths of time. The highest levels of cell attachment were observed for surfaces which had been plasma-treated for one min. Surface analyses indicated that although PC treatments dramatically improved surface wettability, the presence of inorganic contaminants was observed with longer treatment times and may have interfered with cell attachment. Further work is suggested to investigate the longer-term phenotypic expression of osteoblasts when grown on implant surfaces.
