牙种植体表面观察及成分鉴定

 

飞纳(Phenom)台式扫描电镜的全景拼图功能可以大视野观察样品,看到样品全貌(图1)。在获得全图的过程中,我们发现了样品表面微区有杂质,通过放大观察,并进行能谱分析,判断为喷砂过程中的 TiO2 颗粒。

通过扫描电镜观察,能够清楚区分不同的处理方法获得的牙种植体,如图 3a,经过酸刻蚀的牙种植体其表面形成网状结构,而图 3b,经过阳极氧化处理的牙种植体其表面形成多孔结构。[1]

· 在牙种植体研究方面,通过全景拼图功能,可以大视野观察样品,看到样品全貌,同时也可以获得高倍的样品微区细节;
· 能谱分析功能可以对感兴趣微区进行能谱分析,确定其成分种类及含量,进而判断微区特征的形成原因;
· 在牙套研究方面,Phenom XL 大仓设计能够不破坏牙套结构,低真空原位观察牙套表面形貌。
