The ceramic veneer in Metal-ceramic crowns and FPDs have potential for fracture. Metal Ceramic Restorations (MCR) are one of most commonly used restorations used in fixed prosthodontics because of their casting accuracy, high strength properties of the metal, durability and the cosmetic appearance of porcelain. Considering the vast differences in modulus between metal and ceramic materials, it is not surprising that mechanical failure of this system can occur. Clinically, such failures often begin as chipping off metal ceramic, leading to failure. In present case, replacement of an extensive prosthesis was done by taking digital impression using CAD/CAM system for fabrication for chairside zirconia bridge using mock -up technique.
