Factors such as impact, fatigue, occlusal pressure, and the mismatch between the physical properties of metals can lead to fracture of porcelain. Fractures often occur in the maxilla (75%) and especially on the labial surface (60%). Porcelain fracture in the anterior region will interfere with the appearance of the patient. Replacement of defective restorations are not necessarily the most practical solution because it takes a long time and cost.One alternative way to handle that is to repair in the mouth. Intraoral repair to do is to use a composite resin and an assortment of treatments on porcelain and metal surfaces such as coarsening with diamond drills, sandblasting and acid hidrofluoride applications.Next,applied primer and the selected composite materials which can be universal composites.
