ABSTRACT:
A filled-resin composition useful for porcelain repair and as a dental composite and therefore made up of non-toxic materials and a method for repairing porcelain or teeth. The composition comprises a methacrylate functional resin usable in dental composites, powdered filler-colorant therein, at least one photoinitiator for the resin in an amount sufficient to initiate polymerization and complete it in depth within about half a minute when exposed to a visible-light output of at least 5,000 foot candles, the photoinitiator being an exciplex of (1) an carbocyclic ketone or acetal and (2) either ethyl-4-dimethyl amino benzoate or ethyl-2-dimethyl amino benzoate, and at least one accelerator-free peroxide curing agent for the resin in an effective amount for completing polymerization within about one-half hour of any portion of the resin not receiving sufficient light to effectuate complete cure before then. The method comprises mixing the components together under ordinary indoor lighting conditions, emplacing the mixture within a few minutes of the mixing, and curing at least a substantial portion of the emplaced mixture in situ for one half-minute under intense visual-light illumintion of at least 5000 foot-candles. Any resin then uncured by light is cured within the next half hour by the peroxide curing agent.
