PFM or porcelain-fused-to-metal restorations provide that perfect balance between aesthetics and strength. Consisting of a metal shell topped with porcelain it makes an ideal type of restoration to be used on both anterior or posterior teeth. Even with technical advances that utilize alternative composites, PFM is still the most widely used form of restoration because of its ability to create both natural looking and durable prosthetics.

Indications

  • Perfect for teeth that require complete coverage where and when aesthetic demands are high
  • Ideal for teeth where destruction in the form of previous restoration trauma may prevent the use of other types of restoration
  • Offers superior retention and strength
  • Best choice if all-ceramic crowns are contraindicated

Contraindications

  • As with all fixed restorations PFM restorations should not be given to those with untreated periodontal disease
  • Considerations should be given to young patients with large pulp chambers because of the high risk of pulp exposure. Alternatively, all-ceramic crowns with less reduction might be preferred
  • A PFM restoration shouldn’t be considered when a more conservative restoration is feasible.
  • Best choice if all-ceramic crowns are contraindicated

Advantages

  • PFM restorations combine the strength of cast metal with the looks of all-ceramic crown
  • Because the axial walls are included in the preparation, retentive qualities are high
  • A seamless appearance can easily be achieved using color matching and staining/blemishing
  • Easy preparation and far less demanding than partial-coverage retainers

Disadvantages

  • Much of the tooth structure is removed to fit a PFM restoration
  • In comparison with all-ceramic restorations, PFM’s have slightly inferior aesthetics
  • PFM restorations can be relatively expensive
