Porcelain-Fused-to-Metal
Our porcelain-fused-to-metal restorations are manufactured by layering porcelain over a high-quality metal alloy substructure. Our expert technicians craft these exceptional solutions in-house at our laboratory. The porcelain and metal are skillfully bonded to eliminate any chance of unesthetic discoloration. These restorations are highly durable due to their underlying metal alloys. They are also highly esthetic due to the porcelain overlay. PFMS are gentle on opposing dentition and can be used for bruxing patients.

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.
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.

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).
