Porcelain
fused to metal restoration is more affordable than all ceramic and zirconia
restoration. Even though they are not as aesthetic as porcelain crowns they are
still a good choice for back teeth restoration.
Porcelain
fused metal or PFMs as they are commonly referred to, consist of a layer of
metal alloy at the base topped by porcelain. They are a hybrid between
porcelain and metal crowns. The entire crown has a metal layer underlying and
porcelain / ceramic on top of it. These are among the popular choices for
dental restorations such as crowns or bridges. Within this category of crowns,
further choice still exists catering to the budget and requirements of the
patient.
While
the reliability and durability of PFMs are beyond question, there is some
limitation of PFM restoration. It can be difficult to create highly esthetic
restorations because of the metal framework. The metal framework must be masked
with opaquer and may remain slightly visible even after layering with
porcelain. This opaquer also prevents light from passing through the
restoration as it would with a natural tooth.
Another
potential problem with PFM restorations is black line after gum recession. Over
time, as gum tissue recedes, the metal margin of the PFM is exposed, creating a
grayish colored line that isn’t esthetically pleasing. This black line problem
is not seen with metal free all ceramic or zirconia restorations.
The
PFM crown is material of choice for crown and long span bridge for back teeth.
Types Of Porcelain Fused To Metal Crowns And Bridge
The
metal framework is a combination of different types of alloys. The type of
framework is one of the factors which decide the price of your porcelain fused
to metal crown. The method of making metal framework is another factor which
decides the price of PFM restoration. The metal framework of PFM can be made by
CAD-CAM technology or hand-made.
