PFM

Porcelain-fused-to-metal crowns are a classic restoration that can be adapted to fit any indication or color. These restorations have the strength and durability of metal, while maintaining esthetic translucency from the layered porcelain. Crafted with a base, noble, or high noble alloy and layered porcelain, our PFM restorations are gentle against opposing dentition. We are able to use the latest in CAD/CAM technology to create precise PFM crowns of the highest quality.

  • Our Porcelain-Fused-to-Metal restorations are available in our Premium, Premium +, and Master product tiers

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.

Contraindications

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.

Preparation

The ideal preparation for PFMs is a chamfer margin preparation. If a porcelain labial margin is prescribed, then a shoulder margin preparation is required.

Cementation

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

Tech Notes

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).
