The adhesive bonding of a fast‐setting system consisting of three different monomers to etched human enamel surfaces was investigated. Combinations of MMA, methacrylic acid, and adducts of glycidyl methacrylate and p ‐substituted phenols have been employed. Best results were obtained with hydrogen or t ‐butyl‐substituted phenols. It is shown that a well‐chosen three‐component system has the advantage of a very low initial viscosity and fast setup times over two‐component systems. Various compositions of three‐component systems were studied. The maximum bond strength between enamel surfaces and the polymer was 80 kg/cm 2 . Setup times as well as in vivo setup times are reported.
