Characterization of the surface topography of implant materials is important for understanding tissue response. We have measured, for the first time, the topography of titanium surfaces used in osseointegrated dental implants. Scanning tunnelling microscopy (STM) which provides 3D real space images was used. In addition to clinical samples, electropolished and anodically oxidized surfaces were also measured. Clinical samples are rather inhomogeneous in character showing grooves and steps with a maximum depth of 0.11 micron. Micropores with an average diameter of about 30 nm are also present. Electropolished samples are rather homogeneous and very smooth, showing steps of 1 to 5 nm in height. The measurements were performed under atmospheric conditions at a resolution in the subnanometer range.
表征植入材料的表面形貌对于理解组织反应很重要。我们首次测量了用于骨结合牙科植入物的钛表面的形貌。使用了能提供三维真实空间图像的扫描隧道显微镜（STM）。除了临床样本外，还测量了电解抛光和阳极氧化表面。临床样本在特征上相当不均匀，呈现出深度最大为0.11微米的沟槽和台阶。还存在平均直径约为30纳米的微孔。电解抛光样本相当均匀且非常光滑，显示出高度为1至5纳米的台阶。这些测量是在大气条件下以亚纳米范围的分辨率进行的。
