Porcelain-Fused-to-Metal (PFM) crown designed for dental restoration applications with chrome cobalt base and ceramic powder overlay for restoring die preparations or pontics.
Definition & Applications
PFM refers to a bilayer restorative system where dental porcelain is fused to a cast metal alloy substructure. It remains indicated for full-coverage crowns, fixed dental prostheses (FDPs) of 3-4 units, and cases requiring significant occlusal load distribution (e.g., bruxers, shortened dental arch). It is also useful when subgingival margin placement is feasible to mask the metal collar.
Key Features
Strong & Long-lasting: Resists biting forces, suitable for back teeth (molars/premolars)
Aesthetic (Moderate): Better than full metal crowns; color-matched to adjacent teeth
Biocompatible: Generally well-tolerated but may cause allergies (e.g., nickel) in rare cases
Cost-effective: More affordable than all-ceramic or zirconia crowns
Clinical Indications
Single or multiple tooth restorations (crowns or bridges)
Teeth with large cavities, fractures, or after root canal treatment
Material Composition
Base Material
Chrome cobalt
Overlay Material
Ceramic powder
A PFM crown consists of a metal alloy substructure covered by layers of porcelain. The metal provides strength and durability, while the fused porcelain mimics the color, translucency, and texture of natural teeth.
