目前，对钛种植体进行表面化学改性已成为牙科种植体的发展策略。本研究调查了市售牙种植体（Nobel biocare TiUnite、Astra AB Osseo-Speed、3 i Osseotite、ITI-SLA）的化学和形态。采用X射线光电子能谱（XPS）和俄歇电子能谱（AES）对样品的表面化学进行了分析。通过扫描电子显微镜研究了形貌。本研究表明，表面性质的主要差异，主要取决于所使用的表面处理。Osseo-Speed、Osseotite和SLA表面的喷砂和酸蚀技术通常主要显示TiO（2），但表面形态不同。相比之下，TiUnite植入物的电化学氧化过程不仅产生微孔表面（孔径：0.5-3.0 μ m），而且由于所用电解质的阴离子的掺入而改变表面化学。因此，TiUnite植入物的含量超过7at.%在XPS分析中，与其他植入物相比，Pin氧化物层和更高量的氢氧化物。在溅射清洁前后，OsseoSpeed植入物中的F检测值为0.3%。皇冠版权（C）2009年由爱思唯尔有限公司代表Acta Materialia Inc.出版。All rights reserved.
Today, surface chemistry modifications of titanium implants have become a development strategy for dental implants. The present study investigated the chemistry and morphology of commercially available dental implants (Nobel biocare TiUnite, Astra AB Osseo-Speed, 3i Osseotite, ITI-SLA). X-ray photoelectron spectroscopy (XPS) and auger electron spectroscopy were employed for the analysis of surface chemistry. The morphology was investigated by scanning electron microscopy. The present study demonstrated the major differences of surface properties, mainly dependent on the surface treatment used. The blasting and acid etching technique for the Osseo-Speed, Osseotite and SLA surfaces generally showed mainly TiO(2), but a varying surface morphology. In contrast, the electrochemical oxidation process for TiUnite implants not only produces microporous surface (pore size: 0.5-3.0 pm), but also changes surface chemistry due to incorporation of anions of the used electrolyte. As a result, TiUnite implants contain more than 7 at.% of Pin oxide layer and higher amounts of hydroxides compared to the other implants in XPS analysis. F in OsseoSpeed implants was detected at 0.3% before as well as after sputter cleaning. Crown Copyright (C) 2009 Published by Elsevier Ltd. on behalf of Acta Materialia Inc. All rights reserved.
