PFM

Predictable and excellent value-for-money

Benefits

Considerations

Benefits

  • High bond strength between metal and porcelain
  • Strength for long-span bridges
  • Marginal integrity
  • Good aesthetics when enough reduction provided
  • Possible to incorporate precision attachments where clinically appropriate

Considerations

  • Currently used more sparingly for anterior teeth given that more aesthetic options are available.
  • Aesthetics (Inadequate tooth preparation can affect aesthetics).
  • Long-term colour stability (become lighter over time).
  • Exposure of restoration margins over time.
  • Metal sensitivity.

Porcelain-Fused-to-Metal (PFM) crowns and bridges are widely trusted and used, as the restorations offer strength, aesthetics, marginal integrity, predictability and excellent value for money. A wide range of alloys are now available to suit every possible case scenario.

WHY PFM?

PFM crowns have the ability to block out a discoloured underlying tooth structure and are adaptable to a wide range of clinical situations. Metal occlusal/palatal surfaces are possible in situations of limited interocclusal space. The easy cementation makes this product popular and is a reason why it has stood the test of time.
