Abstract
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.
