초록 ▼

The invention describes a transparent, elastomeric dental cement composition suitable for temporary or provisional restorations that comprises: (a) at least one multifunctional oligomer or prepolymer as a binder; (b) at least one finely divided filler; and (c) at least one initiation system for polymerization. The cement has a high translucency which does not alter the color shade of a temporary prosthesis or appliance and great flexibility which allows the dentist to remove the temporary appliance easily and clean both the temporary appliance and the dental tissues easily. The invention also describes a method of using the transparent, elastomeric dental cement.

대표청구항 ▼

[ What is claimed is:] [1.] An elastomeric temporary dental cement composition comprising:(a) a resinous mixture comprising free-radically polymerizable resin, the resin including at least one binder selected from the group consisting of a multifunctional oligomer and a multifunctional prepolymer said binder having an effective molecular weight to impart an elastomeric feature, and said resinous mixture being liquid at ambient temperature;(b) at least one finely divided filler, wherein the refractive index of the liquid matrix is within about +/-0.02 of the refractive index of the filler; and(c) at least one initiation system for polymerization, wherein, after polymerization, the cured elastomeric dental cement has a translucency of at least about 30% at a thickness of 1 mm.
