How PFM bridge are made?
Porcelain fused to metal crowns and bridges (PFM’s), also known as a VMK, is made from a metal base with layering or veneering of ceramic to provide a natural tooth-like restoration. PFM’s have been used since the 1950s and are still a popular restoration.
What is PFM dental?
Porcelain-fused-to-metal (PFM) crowns have been considered the gold standard for the repair of damaged teeth. PFM crowns have good mechanical properties, satisfactory esthetic results, and an acceptable biological quality needed for periodontal health. However, PFM crowns have some limitations that may limit their use.
Why is porcelain fused to metal crown?

Which is better PFM or zirconia?
Why Use Zirconia Over PFM? Zirconia offers superior strength and durability for dental crowns. It is at least three times stronger than porcelain or PFM restorations. Unlike porcelain, zirconia can withstand wear and tear without chipping, which is why zirconia restorations tolerate extreme chewing and bruxism.
What alloy is used for PFM?
Alloys Used to Fabricate PFMs When high-noble is chosen, the product will have a composition of over 60% noble metal that could be gold, platinum, or palladium, that must be more than 40% gold. The remaining metals in this alloy can consist of silver and copper with smaller amounts of iridium, indium, zinc or rhenium.
