Metal-Ceramic (PFM)

Also available in the Quest Range

 

Porcelain-Fused-to-Metal (PFM) crowns and bridges are widely 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. Hypersensitive or allergic patients can have the choice of Titanium, Nickel and Beryllium-free or noble or high-noble alloy copings.

Ceramics employed are issued with US IdentCeram® certificates to verify the American Dental Association classification and content of the restorative materials.

Benefits

  • High bond strength between metal and porcelain
  • Strength for long-span bridges
  • Marginal integrity
  • Biocompatible
  • Aesthetics
  • Ability to block out discoloured underlying tooth structure
  • Can 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
