PFM

Porcelain-fused-to-metal restorations are a timeless restorative standard within the dental industry due to their long held clinical success. Fabricated out of noble and high noble alloys, these crowns provide valuable biocompatibility that ensures continued periodontal health. Our expert technicians carefully bond the highly esthetic porcelain to a metal substructure, eliminating any risk of unsightly discoloration. The strength of the metal provides extreme stability and longevity. Our team utilizes the latest in CAD/CAM technology to ensure ideal precision for our PFM restorations. Your patients will be highly satisfied with the final result of this solution.

Indications

Our PFMs can be used for crowns and bridges (up to fourteen units). PFMs can be manufactured to nonprecious or semiprecious copings, and can be used in conjunction with cast partials and implants.

Contraindicated when the patient has a metal allergy or when the size of the tooth pulp is negligibly smaller, thus compromising the tooth preparation process. It is also contraindicated when the clinical tooth crown is very short and lacks the required stability including retention that is enough to provide the space for porcelain and metal.

The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required. Feather-edge margin preparations are indicated for full-cast restorations.

  • Panavia 21 – tin plated
  • Glass ionomer cement (GC Fuji, GC America)
  • Zinc Phosphate Polycarboxylate
  • Resin Ionomer cement (RelyX, 3M ESPE)

If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool. To contour the ceramic, polish with a pink rubber wheel and diamond polishing paste (Brasseler, Shofu, Vident).
