Porcelain-fused-to-metal (PFM)
Porcelain-fused-to-metal crowns and bridges: a long-proven restoration with the support of a metal framework.
What it is
A PFM restoration has a cast or milled metal framework with porcelain fused over it. The framework provides strength and the porcelain gives a tooth-coloured surface.
When to choose it
- Longer-span bridges that benefit from a metal framework
- Cases where the clinician prefers a metal substructure
- Matching existing PFM restorations in the mouth
Things to consider
PFM needs enough tooth reduction for both the metal and the porcelain. If the gum recedes, a dark margin can become visible, so all-ceramic options are often chosen for front teeth.
What to send us
- A scan or impression
- The margin design (metal collar or porcelain margin) on the RX form
- The shade and photos
- The opposing arch and bite
Frequently asked questions
Is PFM still used?
Yes. It has a long track record and remains a reliable choice, especially for longer bridges, although all-ceramic materials are now common for front teeth.
Which metal alloys do you use?
Note any alloy preference or allergy on the RX form and call the lab to discuss the options for your case.
