Porcelain Fused Metal
Porcelain-fused-to-metal dental crowns (PFM’s) are somewhat of a hybrid between metal and porcelain crowns.
When they are made, the dental technician first makes a shell of metal that fits over the tooth. A veneering of porcelain is then fused to this metal (in a high-heat oven), giving the crown a white tooth-like appearance.
ADVANTAGES:
- They’re strong. – Due to their great strength, PFM dental crowns can make a good choice for either front or back teeth.
- They’re natural looking. – For some people, and some applications, the big advantage of a PFM crown over an all-metal one is simply that it’s tooth coloured.
Given its balanced distribution of particles, the metal-ceramic exhibits excellent modelling properties and high stability, even after several firing cycles.
