使用传统硅基牙科陶瓷的标准方法难以实现树脂与氧化锆陶瓷的结合，该方法采用硅烷偶联单体作为底漆。在这项研究中的假设是，硅烷偶联低聚物，硅烷偶联单体的缩合产物，将是一个更合适的氧化锆底漆。为了证明这一假设，复合树脂和氧化锆之间的剪切粘结强度进行了比较后，应用硅烷偶联单体或低聚物。与施加单体时相比，施加硅烷偶联低聚物的非活化乙醇溶液后的剪切粘结强度增加。在施加硅烷偶联剂之后在110 ℃下对氧化锆进行热处理对于提高复合树脂水泥与氧化锆之间的剪切粘结强度是必要的。
Resin bonding to zirconia ceramics is difficult to achieve using the standard methods for conventional silica-based dental ceramics, which employ silane coupling monomers as primers. The hypothesis in this study was that a silane coupling oligomer a condensed product of silane coupling monomers would be a more suitable primer for zirconia. To prove this hypothesis, the shear bond strengths between a composite resin and zirconia were compared after applying either a silane coupling monomer or oligomer. The shear bond strength increased after applying a non-activated ethanol solution of the silane coupling oligomer compared with that achieved when applying the monomer. Thermal treatment of the zirconia at 110 degrees C after application of the silane coupling agents was essential to improve the shear bond strength between the composite resin cement and zirconia.
