PFM

When esthetics is a concern for a patient, our porcelain-fused-to-metal restorations are an excellent choice with dependable durability. PFMs are a timeless standard due to their longevity and increased esthetics when compared to alternative metal-based solutions. Our team crafts these crowns and bridges by layering porcelain to a high-quality metal alloy substructure. We carefully bond the porcelain to ensure there are no unflattering esthetic issues such as discoloration. The underlying metal offers dependable stability and strength for longlasting results. These crowns are still widely prescribed due to their high rate of clinical success and biocompatibility. They have also been shown to help ensure continued periodontal health in patients.

Features:

  • Gentle on Opposing Teeth
  • Esthetic Porcelain
  • High-Quality Metal Alloys
  • High Rates of Clinical Success

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.

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).
