To investigate the predictability and the outcome of surface modification techniques, including anodization. Four surface modification techniques were evaluated in this in-vitro study: sandblasting (S), polishing+anodizing (PA), sandblasting+anodizing (SA), polishing+etching+ anodizing (PEA). Color coordinates L*, a* and b* were collected using a spectroradiometer. Color differences between all groups were quantified by use of ΔE. A possible influence of group membership was evaluated using 1-way ANOVA. Pair-wise inter-group comparisons were performed using post-hoc Tukey tests. PA specimens were the brightest and showed a pronounced yellowish and reddish hue. S and SA groups were significantly darker and predictability of outcome was higher compared to another groups. The most predictable surface treatment method is sandblasting. Anodizing techniques come along with the brightest and most chromatic color impression of the titanium.
为研究包括阳极氧化在内的表面改性技术的可预测性及结果。在本体外研究中评估了四种表面改性技术：喷砂处理（S）、抛光+阳极氧化（PA）、喷砂+阳极氧化（SA）、抛光+蚀刻+阳极氧化（PEA）。使用分光辐射计收集颜色坐标L*、a和b。通过ΔE对所有组之间的颜色差异进行量化。使用单向方差分析评估分组的可能影响。使用事后Tukey检验进行组间两两比较。PA样本最亮，呈现出明显的黄红色调。S组和SA组明显更暗，与其他组相比结果的可预测性更高。最具可预测性的表面处理方法是喷砂处理。阳极氧化技术会带来钛最亮且最具色彩的颜色印象。
