Metal ceramics, also known as porcelain-fused-to-metal (PFM) restorations, are used in dental laboratories for crowns and bridges. They consist of a metal alloy base (either non-precious or precious) with a porcelain layer for esthetics. The metal provides strength, especially for posterior teeth, while the porcelain layer mimics natural tooth appearance. Digital technologies like CAD/CAM may be employed in fabrication. Metal ceramics are versatile, suitable for both single-unit and multi-unit restorations, but considerations include a potential grayish tint near the gumline due to the metal.
