Porcelain‐fused‐to‐metal (PFM) is presently the most popular crown and bridge technique. Its success is attributable to the use of a metal substructure to support the porcelain, resulting in good esthetics, limited ceramic flexure, and better longevity than all‐porcelain restorations. A new concept suggests encapsulating the metal substructure with ceramic and placing the insert under the occlusal surface, thereby combining the best properties of the esthetics of porcelain and the support of metal to achieve improved restorations. CLINICAL SIGNIFICANCE The ceramometal bonded restoration (CMBR) addresses the known limitations of PFMs by providing a more esthetic, more conservative, and more durable alternative. The CMBR eliminates the potential for tooth darkening, leaves more of the natural tooth intact, and offers good resistance to fracture or displacement under occlusal forces. This combination of features makes the CMBR inlay or onlay an excellent alternative for the conservative esthetic restoration of posterior teeth.
