Porcelain fused with metal crowns, commonly referred to as PFM, is a type of dental crown that combines the strength of metal with the aesthetic appearance of porcelain. The metal substructure is typically made from a non-precious metal alloy or high noble metal, which provides the crown with strength and durability. A layer of porcelain is then fused to the metal, giving the crown a natural-looking tooth-colored appearance. PFM crowns are often used for back teeth restorations because of their strength and ability to withstand heavy biting forces. Patients who prefer a restoration that is more aesthetically pleasing than an all-metal crown frequently choose them. But with time, the restoration's appearance may be impacted by the metal border at the gum line being visible.
