Porcelain-Fused-to-Metal (PFM)

The porcelain-fused-to-metal restorations from Louvre combine this timeless standard with state-of-the-art technology and expert-level porcelain layering. These crowns are crafted by layering esthetic porcelain over a substructure comprised of high-quality metal alloys, including high noble white, semi-precious, high noble yellow, and non-precious. Our technicians utilize their years of experience in crafting PFMs to ensure the highest esthetic outcome. The porcelain is carefully bonded to eliminate any discoloration. Our PFM restorations are gentle on opposing dentition, biocompatible and have a high rate of clinical success.

A PFM Restoration for Every Case

We created our three product lines to fulfill our mission of being a dental laboratory that is accessible for a wide variety of dentists. Whether you are in need of a more economically priced crown or high-end cosmetic restoration, Louvre Dental Laboratory has the PFM solution for you. Due to the skill required to fabricate an excellent PFM restoration, this product is only available in our Classic and Masterpiece Series.

The Masterpiece Series

The Masterpiece PFM ensures high esthetics and strength for every case. Fabricated by one of our Master Dental Technicians, the PFM is fully layered with porcelain. The metal substructure is made out of high-quality alloys and is also expertly crafted to be fully anatomical.

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.

  • 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).
