Porcelain Fused to Metal (PFM)
A hybrid construction, the most common type of crown, PFM or the latest generation known as Porcelain on Metal (POM) are cast metal substructure that have a porcelain cover. Teeth coloured ceramic is layered on top of the metal framework providing outstanding strength. The porcelain to metal fusing is therefore heavier and thicker than full ceramic crowns. With their strength, they’re a tremendous option for front and back teeth.
Usually of a single build construction, which makes the out layer of the crown less likely to fracture or break. For patients that suffer from grinding during sleep then PFM is preferable or for when long bridges are necessary.
PFM’s have a well documented history among all dentists and patients for their outstanding lasting service.
Made from high metal substructure, PFM is biocompatible and often used with gold metal alloys (price for gold may vary dependent upon current Caret pricing and weight), since they’re less reactive to allergies. Being thicker than all-ceramic crowns, PFM’s have larger potential to eventually wear nearby teeth or opposing teeth that they bite against.
The newest technological method of metal, is a method known as Porcelain on Metal (POM). POM utilize new methods of synthetic porcelain.
