Porcelain fused to metal crowns can be referred to as full-cast crowns which has porcelain fused on most or all parts of the tooth. They are a hybrid between porcelain and metal crowns. The entire crown has a metal layer underlying and ceramic on top of it. The metal coping is thin, strong, and perfectly fits the prepared teeth. Metal alloys with a high melting temperature are used to fuse the porcelain to the surface and prevent the metal from melting. It ensures the porcelain to bond without changing its color. PFM crowns are more affordable than all ceramic crowns. Even if they aren't as aesthetically as all ceramic crowns, they are still a good option for posterior restoration. Porcelain fused to metal crown has nice mechanical properties, esthetic results, and an acceptable biological quality needed for periodontal health.
