Porcelain-Fused-to-Metal
The Porcelain-Fused-to-Metal (PFM) restorations from GKY continue to be a well trusted product by many of our clients. These restorations offer great esthetics, superior fit and margin adaption compared to other products. Fabricated by layering esthetic porcelain over a substructure made with high-quality metal alloy, these restorations ensure both long-lasting strength and beauty. They are a timeless standard crafted with expert 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.
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. 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).
