Porcelain-Fused-to-Metal Crown
A metal-ceramic crown with a milled CoCr or noble alloy framework, still the most economical long-span option with predictable fit.
Frameworks are milled rather than cast, which removes the shrinkage variable and gives a consistent marginal fit. Porcelain is layered with a shoulder ceramic to hide the metal collar in the aesthetic zone.
We recommend PFM for long-span bridges, patients with limited budget for full ceramic, and cases where a metal palatal or lingual surface is acceptable.
