This study evaluated the adhesion of composite resin to five different surface conditions of porcelain samples that were treated with three kinds of silane agents. Two of these were commercially available Porcelain Liner M and Tokuso Ceramic Primer, and one was an experimental agent. The commercially available silane agents gave high bond strengths without hydrofluoric acid etching, which gave the greatest roughness on the porcelain surface. One component of these commercially available silane agents was gamma-methacryloxypropyl trimethoxysilane, and the other was the carboxylic acid. As a result of the effective formation of siloxane bonds by mixing with acid solution, porcelain surface conditions did not affect the bond strengths.
本研究评估了复合树脂与经三种硅烷试剂处理的瓷样本的五种不同表面条件之间的黏附力。其中两种为市售的烤瓷衬层材料M和托库索陶瓷底漆，另一种为实验试剂。市售硅烷试剂在不进行氢氟酸蚀刻的情况下能产生较高的粘结强度，氢氟酸蚀刻会使瓷表面粗糙度最大。这些市售硅烷试剂的一种成分是γ-甲基丙烯酰氧基丙基三甲氧基硅烷，另一种是羧酸。通过与酸溶液混合有效形成硅氧烷键的结果是，瓷表面条件不会影响粘结强度。
