Studies on the tissue adhesive capability to titanium by dynamic wettability test and cell attachment, in vitro

To investigate better methods of surface treatment of cleaning and sterilization for a titanium implant, measurements of contact angles to water and the critical surface tension were made and the iniial cell attachment on the treated surfaces of cp titanium was also observed. The results showed that cleaning using acetone, or acetone with 4% hydrofluoric acid treatment, yielded smaller contact angles and high critical surface tension values. On the other hand, treatment of detergent cleaning represented a large contact angle and a low critical surface tension. However, the initial cell attachment did not differ, regardless of these surface treatments and/or sterilization.
