At Bolton Dental Laboratory, we take pride in crafting our porcelain-fused-to-metal restorations in-house at our Wisconsin laboratory. Our skilled technicians fuse a layer of porcelain onto a layer of high-quality metal to create crowns and bridges that are not only durable but also highly esthetic. We take extra care to bond the porcelain carefully to eliminate the chance of any unesthetic discoloration. The metal substructure ensures that the restoration is long-lasting and can withstand force while ensuring optimal periodontal health. Our porcelain-fused-to-metal restorations are also gentle on opposing dentition, making them an ideal choice for patients who grind their teeth.
Features:
- Durable and Long-Lasting
- Highly Esthetic
- Gentle on Opposing Dentition
- Suitable for Bruxism
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.

- Glass ionomer cement (GC Fuji, GC America)
- Zinc Phosphate Polycarboxylate

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).
