A crown is an artifical restoration that fits over the remaining part of a prepared tooth, making
it strong and giving it the shape of a natural tooth. Crowns are an ideal restoration for teeth
that have been broken, or have been weakened by decary or a very large filling.

Crowns can be made of a variety of different materials.
Porcelain bonded to precious metal:
Porcelain-fused-to-metal dental crowns are somewhat of a hybrid between
metal crowns 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 over this metal (in a high heat oven), giving the crown a white tooth
-like appearance. Depending on the requirements of your situation, these
crowns are sometimes made where the porcelain veneer only covers those
aspects of the crown that is readily visible (meaning the other portions of the
crown have a metal surface). In other cases these crowns are pretty much fully
surfaced with porcelain. Porcelain-fused-to-metal dental crowns can be a
good choice for either front or back teeth. These crowns are strong enough to
withstand heavy biting pressures and at the same time can have an excellent
cosmetic appearance.

All-ceramic crowns:
This modern technique offers a metal-free alternative. These crowns can
possess a translucency that makes them the most cosmetically pleasing of all of the different
types of dental crowns. Although they can be very life like in appearance, the overall strength of
all-porcelain dental crowns is less than other types of crowns. While they can be a good choice
for front teeth, due to the hefty chewing and biting forces that humans can generate, all-porcelain
dental crowns may not be the best choice for back teeth. Your dentist's judgement will be
required on this point.
Gold alloy crowns:
Gold is one of the oldest filling materials. Today it is used with other metal
alloys to increase its strength, which makes it a very hardwearing restoration. These crowns are
white or gold in colour. The crowns are fixed in place with special dental cement or adhesive.
Zirconium crowns:
One of the most difficult areas in dentistry today is the restoration of dental
structures with biocompatible materials that are strong enough to withstand the forces of
chewing (500-1000lbs pressure on molar teeth). Recent technology from Germany now offers
a material that has overcome most of the pitfalls of present day products. Patients now have a
choice of a material that is aesthetic, strong, pure, biocompatible and capable of being used
for single and long span dental bridgework. That material is called Zirconium oxide. It is the
optimal material for crowns: tasteless, radiopaque, no pulp irritation because there is no need
to use adhesive cements and minimal invasive preparation by dentist.
