方法：采用新鲜的人离体牙，对不同条件下贴面烤瓷与牙齿的粘接强度进行测试；
Methods: Bond strength were measured in different conditions between veneer porcelain samples and fresh extracted teeth.
结论：使用酸蚀剂和硅烷偶联剂都能提高贴面烤瓷的粘接强度，但酸蚀剂起主要作用。
Conclusions: Both etching of porcelain surface and use of silane yield higher bond strength, but the etching is the chief factor.
