通过剪切试验测试其强度，扫描电镜及能谱分析结合界面的微观结构，为提高氧化锆全瓷修复体的成功率提供理论依据。

方法：将氧化锆瓷块(Sirona)胚体切割并通过烧结制成10mm×5mm×5mm大小试件44个，将试件随机分为四组，每组11个。

处理方式如下：实验组l基底瓷结晶后做喷砂处理，然后烧结饰面瓷；实验组2基底瓷结晶后，先做纳米氧化锆涂层烧结，然后烧结饰面瓷；实验组3基底瓷结晶后，先做喷砂处理，然后做纳米氧化锆涂层烧结，最后烧结饰面瓷；对照组基底瓷结晶后常规抛光，然后烧结饰面瓷。

以上各组基底瓷材料全部采用粉浆涂塑法烧结5mm×5mm×5mm厚的饰面瓷。

每组lO个试件通过电子拉伸机测试结合界面的剪切强度，每组随机抽取1个基底瓷及双层瓷试件，采用扫描电子显微镜、能谱分析方法，观察结合界面的微观结构，研究氧化锆基底瓷与饰面瓷之问的结合情况。

结果：1．剪切强度测试结果实验组l所测得的剪切强度为17．96士0．3l MPa，实验组2所测得的剪切强度为20．14士0．68 MPa，实验组3所测得的剪切强度为24．65士0．67 MPa，对照组所测得的剪切强度为14．06士0．44肝a。

各组结果之间的差异有统计学意义(P<0．01)。

2．扫描电镜观察结果实验组1的氧化锆试件表面呈现均匀一致的粗糙面，可见不规则的凹陷凸起；4万方数据双层瓷的结合界面有明显的嵌合。

实验组2的氧化锆试件表面呈现清晰的浅凹和嵴，形态较规则，溶胶无开裂，无缝隙；双层瓷的结合比较紧密，可见相互嵌合。

实验组3的氧化锆试件表面呈现均匀一致的粗糙面，可见不规则的凹陷凸起，溶胶无开裂，无缝隙；双层瓷的结合界面有明显的嵌合。

对照组的氧化锆试件表面形成清晰的浅凹和嵴，形态较规则；双层瓷的结合界面比较平直，结合较为紧密。

3．厶皂谱分析结果各组中zr元素在瓷一瓷结合界面处浓度下降特别明显，其中在实验组2和实验组3的饰面瓷侧的Zr元素含量又有升高；在实验组1的饰面瓷侧检测到微量zr元素；在对照组的饰面瓷侧未检测到Zr元素。

各组中Si元素在瓷一瓷结合界面处浓度下降较快，氧化锆基底瓷侧可检测到Si元素。

各组中Al元素在瓷一瓷结合界面处浓度下降较为缓慢。

结论：1．与对照组相比，单独喷砂处理或纳米氧化锆涂层处理，均能提高氧化锆基底瓷与饰厩瓷的结合强度。

2．与对照组及单独喷砂处理或纳米氧化锆涂层处理相比，喷砂处理结合纳米氧化锆涂层处理能显著提高氧化锆基底瓷与饰面瓷的结合强度。

3．单独纳米氧化锆涂层处理或喷砂结合涂层处理后，双层瓷界面间有锆元素的扩散，提示可能存在化学结合。
