Porcelain Fused to Noble Metal crown is a type of dental crown that consists of a metal substructure (usually noble metal, such as gold or palladium) covered with a layer of tooth-colored porcelain.
These crowns are made from Noble Metal – a combination of Palladium (Pd), and/or Platinum (Pt)3 25%.
The process involves two main steps. First, the metal substructure is crafted to fit the tooth. Then, porcelain is fused onto the metal in layers to create a natural-looking appearance.
