This timeless standard for dental restorations is crafted by fusing a layer of porcelain to an underlying layer of high-quality metal alloys. The porcelain overlay is carefully bonded in order to eliminate the chance of discoloration, which can ruin the esthetics of the final restoration. The metal provides stability and strength, which makes it an excellent option when compared to crowns made from alternative materials. The porcelain provides the restored tooth with lifelike esthetics. These crowns have stood the test of time due to their clinical success and biocompatibility, which helps ensure continued periodontal health. PFMs are also gentle on opposing dentition. The use of CAD/CAM technology allows our clinicians to fabricate this traditional solution with extreme precision.
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).
