PFM

PFM is the timeless standard for dental restorations. They are crafted by carefully fusing a layer of porcelain to an underlying layer of high-quality metal alloy. The metal provides stability and strength, which makes it a strong contender against crowns made from alternative materials. The porcelain provides the restored tooth with a lifelike appearance. These crowns are still a popular option due to their high rate of clinical success and their biocompatibility that 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.

Features:

  • Gentle on opposing dentiton
  • Biocompatible
  • Careful bonding of porcelain eliminates discoloration
  • CAD/CAM fabrication

Changed color of anterior teeth, Incorrect shape of tooth or position in dental arch, Enamel defects such as enamel hypoplasia, attrition of teeth as a consequence of trauma, wide interproximal spaces like diastema.

Bruxism and parafunction, Pathology of bite, more than 50% of enamel affected by pathology.

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
  • Resin Ionomer cement (RelyX, 3M ESPE)
For facial reduction three wheel diamond depth cutter should be used for orientation grooves. For proximal reduction - round end tapered diamond bur is used as an extension for facial reduction.
