PFM

PFM

Porcelain-Fused-to-Metal (PFM) crowns and bridges are a timeless standard in the dental industry. Our team crafts these restorations by carefully fusing hand-layered porcelain to an underlying layer of high-quality metal alloy. The metal provides stability and strength, which makes it a strong contender against crowns made from alternative materials. The porcelain provides the restored tooth with a lifelike appearance. These crowns are still a popular option due to their high rate of clinical success and their biocompatibility that helps ensure continued periodontal health. PFMs are also gentle on opposing dentition.

Traditional PFMs

Our traditional Porcelain-Fused-to-Metal (PFM) crowns and bridges are crafted by layering porcelain to traditionally cast metal alloy substructures.

Digital PFMs

Our Nakanishi Noble Digital Porcelain-Fused-to-Metal (PFM) crowns and bridges offer exceptional fit and consistency. These PFMs are digitally and designed and contoured using CAD/CAM technology.

Indications

Our PFMs can be used for crowns and bridges (up to fourteen units). PFMs can be manufactured to nonprecious, semiprecious, and yellow high noble 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).
