Procure Hard Reline by Keystone Industries is an excellent chair side, 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 chair side. 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. It is made to minimize absorption of water, to prevent bacterial build-up, and to exhibit stable color. One kit averages 25-30 relines.
