ABSTRACT:
Visible light curable dental restorations are provided having improved color stability. According to a preferred embodiment, visible light hardenable restorative materials are formulated from a major proportion of inorganic filler and a minor proportion of a resin component comprising a binder resin selected from the group of acrylated polyesters, acrylated polyesters reacted with an isocyanate, and hydroxyalkyl acrylic esters reacted with an isocyanate, polymerizable acrylic diluent monomer in an amount sufficient to control the viscosity of the resin component, and a photosensitizing system comprising of from about 0.05% to about 0.50% by weight of the restorative material of an alpha diketone together with an amine reducing agent. American Dental Association color stability standards are met by these compositions.
