Porcelain-Fused-to-Metal

Oratech offers PFM crowns and bridges, which are a timeless standard in the dental industry. They are crafted by carefully fusing a layer of porcelain to an underlying layer of high-quality metal alloy. Our PFMs are available in non-precious, noble, and yellow or white high noble. 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. The use of CAD/CAM technology allows our technicians to fabricate this traditional solution with extreme precision.

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).
