This case report highlights an esthetic replacement of defective metal ceramic bridge by a ceramic zirconia one after performing the necessary changes in preparations to ensure esthetic and function.

Current ceramic materials offer preferred optical properties for highly aesthetic restorations. The inherent brittleness of some ceramic materials, specific treatment modalities, and certain clinical situations require resin bonding of the completed ceramic restoration to the supporting tooth structures for long-term clinical success. The purpose of the present paper is to present the clinical bonding steps of an IPS e max cad endocrown fabricated by CAD/CAM system to restore a damaged first mandibular molar endodontically treated.
