PFM Crown

A PFM crown, short for Porcelain-Fused-to-Metal crown, is a common type of dental restoration used to restore damaged or weakened teeth. These crowns consist of two main components: a metal substructure and a layer of tooth-colored porcelain. The metal substructure, often made of alloys like nickel-chromium or cobalt-chromium, provides strength and durability, making the crown suitable for withstanding biting forces and maintaining the integrity of the tooth structure. The porcelain layer is then fused to the metal substructure, mimicking the appearance of natural teeth. This porcelain outer layer is carefully crafted to match the color and translucency of surrounding teeth, resulting in a restoration that blends seamlessly with the natural dentition. PFM crowns offer a balance between strength and aesthetics, making them a popular choice for dental restorations, particularly for posterior teeth where strength is crucial. However, one drawback of PFM crowns is the potential for the metal substructure to create a visible dark line at the gum line over time, especially in patients with receding gums.
