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 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).
