Salvaging fractured porcelain crowns with a direct composite repair technique.
Fractures of porcelain crowns, particularly on anterior teeth, require a rapid resolution. While repair can be achieved with relative ease using a composite resin material, detailed investigation of the cause of the fracture is mandatory to avoid repetition, and to safeguard longevity of both the affected restoration and abutment tooth. Treatment of fractured prostheses should not be implemented unless thorough evaluation is performed to determine potential damage to abutment and surrounding teeth. The ensuing discussion highlights etiology, clinical presentations, and guidelines for repairing fractured restorations.
