title: Repair of defective Class I composite resin restorations.
abstract: Composite resin restorations undergo dimensional changes that can eventually result in marginal defects. Unlike silver amalgam restorations, which usually should be completely removed before the tooth is restored again, bonded composite resin restorations can often be repaired. This report demonstrates a step-by-step technique for repairing a defective Class I composite resin restoration with a new application of resin after elimination of the defect. The method has proved successful over the last 8 years.
