Porcelain Fused to Metal

Porcelain Fused to Metal

One of the most popular fixed restorative options, porcelain fused to metal crowns and bridges have a proven track record. Our ceramic crowns provide the esthetic translucency of handcrafted porcelain with the biocompatibility and strength of a cast metal understructure.

Indications

Our PFMs can be used for crowns and bridges (up to fourteen units). PFMs can be manufactured to non-precious, semi-precious, and yellow high noble copings and can be used in conjunction with cast partials and implants.

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.

Feather-edge margin preparations are indicated for full-cast restorations.

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).
