A Comprehensive Guide to Dandy's PFM Restorations

PFM crowns, also known as porcelain-fused-to-metal crowns, are dental restorations that combine the strength of a metal substructure with the aesthetic appeal of porcelain, providing both durability and a natural-looking appearance. The porcelain covers the entire metal core, leaving no metal exposed or a metal collar visible around the base. The metal core is fabricated from various metals chosen for their strength and/or biocompatible properties. PFM crowns require less retraction and smaller margins, making them an ideal choice with minimal occlusal space.
