Background: The aim of this study was to evaluate the macro- and micro-structure and the chemical composition of the surface of 5 different commercially available dental implants. Roughness values were also calculated. Materials and Methods: 1 zirconia implant (NobelPearl of Nobel Biocare) and 4 titanium implants, Syra (Sweden&Martina), Prama (Sweden&Martina), T3 (Biomet 3i), and Shard (Mech&Human), were analyzed through SEM-EDX analysis and quantitative evaluation of surface roughness (1 sample), and XPS chemical analysis (1 sample). Surface roughness was quantitatively assessed using the stereo-SEM method (SSEM). The following area roughness parameters were calculated, according to ISO25178: Sa, Sz, and Sdr. Results: From the SEM observations, all the implants analyzed presented modern well-developed micro-structures as the result of the specific process of double acid etching alone or combined with other additional treatments. Roughness values were generally greater at the level of the implant body and lower at the collar. The chemical characterization of the implant surfaces exhibited excellent results for all of the implants and indicated good care in the production processes. Conclusions: All the samples were well-conceived in terms of topography and surface roughness, and clean in terms of chemical residues.

不同宏观和微观结构的钛和氧化锆种植体的形态和化学特征

背景：这项研究的目的是评估5种不同的市售牙科植入物的宏观和微观结构以及表面化学成分。还计算粗糙度值。材料和方法：通过SEM-EDX分析和定量评估分析了1个氧化锆植入物（Nobel Biocare的NobelPearl）和4个钛植入物，Syra（瑞典和马丁纳），Prama（瑞典和马丁纳），T3（Biomet 3i）和Shard（Mech＆Human）。表面粗糙度（1个样品）和XPS化学分析（1个样品）。使用立体SEM方法（SSEM）定量评估表面粗糙度。根据ISO25178计算以下区域粗糙度参数：Sa，Sz和Sdr。结果：从SEM观察，单独的双酸蚀刻或与其他附加处理相结合的特定工艺的结果是，所有分析的植入物均呈现出现代发达的微结构。粗糙度值通常在植入物本体的水平处较大，而在轴环处较低。植入物表面的化学特性对所有植入物均显示出优异的结果，并在生产过程中显示出良好的护理。结论：所有样品在形貌和表面粗糙度方面都经过精心构思，在化学残留物方面也很干净。植入物表面的化学特性对所有植入物均显示出优异的结果，并在生产过程中显示出良好的护理。结论：所有样品在形貌和表面粗糙度方面都经过精心构思，在化学残留物方面也很干净。植入物表面的化学特性对所有植入物均显示出优异的结果，并在生产过程中显示出良好的护理。结论：所有样品在形貌和表面粗糙度方面都经过精心构思，在化学残留物方面也很干净。
