摘　　要：用氢氟酸(HF)蚀刻瓷贴面是增强瓷与粘接树脂结合强度的主要方法之一。本研究采用扫描电镜揭示三十个氢氟酸浓度和处理时间点下陶瓷蚀刻表面和断面的形貌特征,阐明蚀刻形貌与酸浓度、时间之间的相互关系,并首次提出烤瓷蚀刻形貌的四级分类,结果表明适宜的浓度、时间搭配点多位于二级蚀刻形貌内。Porcelain laminate veneers has been a kind of popular treatment modality for their aesthetics and less tooth reduction. It is necessary to do morphology analysis for the better understanding of details of porcelain surface after HF acid etching under 5 different HF concentrations and 6 exposing times,which were examined by scanning electron microscope. It was the first time to classify the etching patterns of porcelain into four groups. It can be concluded that the majority of suitable HF concentrations and exposing times belong to Pattern Two.
