Repair of bis-acryl provisional restorations using flowable composite resin.

Provisional restorations provide interim coverage for prepared teeth while fixed definitive restorations are fabricated. Several types of autopolymerizing acrylic resins have been used for many years to fabricate provisional restorations. In recent years, bis-acryl resin composite material has gained popularity among clinicians for the direct fabrication of provisional fixed restorations. Occasionally, deficiencies may occur while fabricating a direct provisional restoration and require chairside repair. This article describes an effective procedure for the use of light-polymerized flowable composite resin for the intraoral repair of bis-acryl provisional restorations.
