This study evaluated the effect of porcelain surface treatment on the shear bond strength of composite resin to various porcelains and porcelain combinations. A variety of feldspathic porcelains with low and medium alumina content were tested. Porcelain/composite resin samples were stored in 37 degrees C water, thermocycled 1,000 times, and tested in shear. A 3-minute etching using hydrofluoric acid significantly increased the bond strength of most of the feldspathic porcelains with low and medium alumina content. Silane application to all types of etched porcelain had no significant effect on bond strength.
本研究评估了瓷表面处理对复合树脂与各种瓷及瓷组合之间剪切粘结强度的影响。测试了多种低氧化铝含量和中氧化铝含量的长石质瓷。瓷/复合树脂样本在37摄氏度的水中储存，进行1000次热循环，然后进行剪切测试。使用氢氟酸蚀刻3分钟显著提高了大多数低氧化铝含量和中氧化铝含量的长石质瓷的粘结强度。对所有类型的蚀刻瓷应用硅烷对粘结强度没有显著影响。
