Improving marginal adaptation of provisional restorations.

The primary objective of a provisional restoration is to promote gingival health before placement of the final restoration. A method for construction of a provisional fixed partial denture with improved marginal adaptation without the use of an indirect method is presented. A preformed shell of the provisional restoration must be fabricated from the diagnostic cast before any operative procedure attempted. The laboratory-made shells are relined intraorally to promote close adaptation to the finishing line of the preparation. A wash of cold-curing acrylic resin is applied to the margins while the bulk of the relining material is at the doughy stage. The technique provider superior results and reduced chairtime.
