The purpose of the current study was to investigate the effect of silane treatment on bond strength to the Esteniaindirect resin composite.
Although the silanization to indirect resin composite enhanced significantly higher bond strength, the bondstrength was affected by the type of silane treatment. The most effective silane system was Two-liquid systemcontaining the phosphoric ester monomer for ... [Show full abstract] the functional monomer, and showed the twice as high bond strengthcompared with the lowest value system. Application of a silane treatment improves the bond strength to indirectresin composite for repair, which was dependent upon the silane treatment systems. The results suggested that theappropriate silane treatment should be selected when repair bonding to indirect resin composite.
