Abstract

To study the bond strength of the silica-resin interface, the treatment effect of 3-methacryloyloxypro-pyltrimethoxysilane (3-MPS) containing acetic and phosphoric acid, and ammonia water as catalysts was examined. The tensile bond strength of the resin composite and the contact angles of a monomer mixture (50% Bis-GMA, 50% TEGDMA) to the glass plates modified with 50mmol/l ethanol solution of 3-MPS added to the catalysts were measured. When the acid and base solution including 5.0vol% phosphoric acid or 5.0vol% ammonia water were added to 3-MPS ethanol solution to 10.0vol%, the tensile bond strengths were significantly higher than those of the control group (non-catalyst group), and the strength of each group after thermal stress showed no significant decrease compared with water immersion for 7 days. The contact angles of the monomer to the glass plates modified with the coupling solution including the acids and base were significantly lower than those of the control group. The 3-MPS solution including 5.0vol% phosphoric acid aqueous solution showed the highest coupling effect among the catalysts.
