Predictable and excellent value-for-money
Benefits
Considerations
- 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
- 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.
