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 for when there is minimal occlusal space.

PFM Material Characteristics

Characteristic PFM
Strength

A higher percentage results in a more gold-like appearance for the crown, while a lower alloy percentage diminishes this gold appearance.

Construction Milled
Material shades

Vita Classical 16-cap with a gold monochromatic core

Au% or karat:

From Most Durable to Least Durable in Material Strength

We currently offer the following three options for PFM units: 

  • High Noble Yellow Gold (41%), 10 karat
  • High Noble Rich Yellow Gold (88%), 21 karat
  • High Noble White Gold (60%), 14 karat
Constraints: Pontic None
Constraints: Span None
Collar Types
  • Porcelain Butt Margin: Porcelain is layered up until the base of the crown.
  • Metal Collar: Visible metal band that can be 180 or 360 degrees
  • Junction: Porcelain is layered up until the margin. There is a thin metal collar that is subgingival and not visible
Metal framework or a bisque try-in We do not offer try-ins or bisque bake processes.
