摘要
为提高氧化锆与粘接材料间的粘接强度,研究的着眼点主要集中在氧化锆的表面处理,包括表面粗化和表面改性。表面粗化包括表面喷砂、选择性渗透蚀刻和Nobelbond技术,旨在增加氧化锆表面粗糙度或使表面形成孔隙,从而增加其机械嵌合力。表面改性包括内涂层技术及各种途径的硅涂层技术(化学摩擦法、热分解法、溶胶凝胶法、四氯化硅蒸汽法),旨在增加氧化锆表面硅元素含量,通过硅烷偶联剂提高其与树脂粘接剂间化学结合力。本文就近年来氧化锆表面处理方法进行综述,旨在帮助口腔医师更好地将氧化锆材料应用于临床。
Zirconia surface treatments are widely studiedto improve the bond strength between zirconia and resin cement. These treatments include surface roughening and surface modification. Sand blasting, selective infiltrationetching, and Nobel Bond technology are employed in surface roughening. This treatment increases surface roughness and porosities, thereby facilitating micromechanical interlocking. Internal coating technique and silicon coating technologies, such as tribochemical treatment, PyroSil Pen technology, sol-gel method, and vapor-phase deposition, are used in surface modification. The treatment increases silicon content, which improves chemical bonding. This review presents the recent findings on zirconia surface treatment methods and suggests a systematic framework for improved clinical applications.
