Porcelain-fused-to-metal (PFM) crowns are dental restorations that combine a strong metal substructure with the aesthetic appeal of porcelain, offering both durability and a natural look. The porcelain layer fully covers the metal core, with the option of a visible metal collar at the base or metal on the occlusal surface if preferred. The metal core is crafted from specific metals selected for their strength and biocompatibility. PFM crowns are ideal for situations with limited occlusal space, as they require less retraction and smaller margins.
