Direct technique for the fabrication of a visible light-curing resin provisional restoration.

A properly fabricated provisional restoration will, among other things, provide acceptable esthetics. Although many materials have been used for provisional restorations, when esthetics is of primary concern, the choice is limited to tooth-colored resin materials. Recently, a tooth-colored, light-activated urethane dimethacrylate resin has been developed. This material has been reported to be useful for many prosthetic applications, including the indirect fabrication of provisional restorations. This paper presents a technique for the direct fabrication of single-unit provisional restorations using this material. The physical properties of this resin and the advantages and disadvantages of the technique are also discussed.
