摘要： The invention provides a denture liner composition for a composite denture based on a phosphonitrilic fluoroelastomer [poly(fluoroalkoxy)phosphazene] curable at atmospheric pressure at temperatures of about 100.degree. C. or less, conveniently by immersing the packed denture flask in a water bath at the appropriate temperature. The composition includes trimethacrylate and dimethacrylate cross-linking agents for increasing liner hardness and decreasing water sorption characteristics of the cured liner. The composition preferably further includes filler materials for increasing the hardness of the liner product. The composite denture is preferably prepared in a one-step process wherein the liner composition material of a single firmness is cured in situ with the denture base material. Alternatively, a firm liner material is cured at the periphery of the denture, and a softer liner material cured at the center; this provides a firm elastic liner adjustable by grinding where soft tissues must be displaced, and a soft elastic liner over bony anatomy, where stresses from chewing are most concentrated and soft tissues are thin. Another possibility lies in curing the soft liner directly to a precured denture as a reline procedure in an pre-existing denture.

C. or less, conveniently by immersing the packed denture flask in a water bath at the appropriate temperature. The composition includes filler materials for increasing the hardness of the cured liner, interpenetrating polymers for increasing firmness and bond strength, and cross-linking agents for increasing the tensile strength and bond strength of the cured liner. The composite denture is preferably prepared in a one-step process wherein the liner composition material of a single firmness is cured in situ with the denture base material. Alternatively, a firm liner material may be cured at the periphery of the denture and a softer liner material cured at the center, in order to provide a firm elastic liner where adjustments must be made by grinding and where the patient's soft tissues must be displaced, and a soft elastic liner over the bony anatomy of the patient where stresses from chewing are most concentrated and the soft tissues are thin.
