Provisional materials: advances lead to extensive options for clinicians.

The progression of provisional materials to bis-acrylics has lead to such improvements as easier handling, improved compressive and tensile strength, less water sorption, and less shrinkage. The end-result is more options for clinicians for high-quality chairside provisional restorations. Newer provisional materials are easy to manipulate and bring increased comfort to the patient. This review of current products affirms that the choices of provisional materials available for the dental professional today are quite extensive and have advanced the quality of interim restorations.
