An excellent chairside, dual cure, hard reline composite that can be added directly to a prepared denture. Mix material to impression-like consistency, apply to denture, and fit at chairside. No heat processing, no methyl methacrylate, and no heat discomfort to oral tissue. The result gives a permanent reline with no thermally induced expansion or shrinkage. The composite has been formulated to absorb very little water, be impervious to bacterial build-up, and is color stable.
