Educational animation visually comparing two types of dental crowns: Porcelain Fused to Metal (PFM) and Full Zirconia. The video demonstrates that PFM crowns, which use a metal substructure, can result in a visible dark gum line, while all-ceramic Zirconia crowns offer superior natural aesthetics, are metal-free, and are more biocompatible for a highly natural-looking final restoration.
