Paper Title:
Enhanced Bioactivity of Sandblasted and Acid-Etched Titanium Surfaces
  Abstract

Two new modified sandblasted and acid etched (SLA) surface methods had been used on commercially pure Ti (Cp-Ti) surface. Scanning electron microscopy investigation showed that modified SLA surfaces had micro- and nano-structure surface topography. Contact angle test showed that surface hydrophilicity was significantly increased after modified SLA surface modification. Human osteoblast-like MG63 cell attachment test showed that modified SLA surfaces would attach more cells than simple SLA surface. The alkaline phosphatase (ALP) activity assay indicated that ALP activity was enhanced on two modified SLA surfaces relative to SLA and mechanically polished Cp-Ti surface at early stage. Thus, subsequent chemical modification of SLA surface seems to be a promising method to generate better bioactive surface properties.
