Reducing marginal flash in the fabrication of direct provisional restorations: a new technique using light-cured resin and transparent silicone.
The optimum placement of bonded indirect restorations depends to a large extent on establishing and maintaining the patient's gingival health during the provisional treatment phase, as inflamed sulcular tissues may compromise subsequent isolation efforts. Gingival health is best achieved by providing provisional restorations of correct emergence profile and accurate margination. This paper introduces a fully-cured direct provisionalization technique that minimizes marginal flash and improves the accuracy of the restoration in a fraction of the production time needed for traditional direct techniques requiring remargination. The technique, which relies on the use of a unique transparent over-impression registration material and visible light-curing provisional composite resin, is described in a case report.
