Repairing of Fractured Metal Ceramic Restorations: Techniques Review

Abstract Statement of the problem: The ceramic veneer in Metal-ceramic crowns and FPDs have the potential for fracture. Fractured porcelain poses a serious and clinical problem. It may be desirable to repair a broken retainer of a fixed prosthesis rather than to remove it and risk the possibility of destroying the entire restoration or damaging the abutment teeth. Techniques: Intra-oral (re-bonding the fractured chip to the fixed restoration or using a composite resin to restore the fractured porcelain), Extra-oral (pin-retained casting, over-casting veneered with porcelain (for repair abutment or pontic), modified over casting or porcelain layer with resin adhesion, and Combination of intra and extra oral techniques. Conclusion: Ceramic repair techniques for fractured ceramic bridge should be consider as an alternative solution instead of replacing a new prosthesis which is coasty, harmful to the abutment teeth and long procedures. This article presents an over view of the different techniques used to repair the fractured porcelain from metal ceramic restoration or remaking of the fractured retainer from a multi-unite FPD.   Key words: Metal ceramic restoration, techniques repair, intraoral, extr oral &nbsp
