In
dentistry, crowns and bridges refers to the restoration
of natural teeth that have been damaged, decayed or lost.
A crown can be made to restore an individual tooth damaged
by decay or fracture back to it's original form and function,
while a bridge is used to replace one or more missing
teeth. These restorations are cemented onto the teeth
and are referred to as "fixed" dentistry as
opposed to a restoration of missing teeth with a removable
appliance or partial denture.
Both procedures
require the use of a local anesthetic and the grinding
or preparation of the teeth, with a crown, the damaged
tooth, with a bridge, the adjacent teeth. A badly decayed
or broken tooth may require that the tooth be "built
up" with a special restorative material during the
preparation of the teeth.
With a fixed
bridge, the prosthesis will span the area of a missing
tooth, known as a pontic, while the two or more adjacent
supporting teeth are called abutments. An impression is
taken of the prepared area, and a temporary crown or bridge
is placed.
The permanent crown will fit considerably better than
the temporary crown, so the temporary crown gives little
indication of how the final crown will fit or feel. It
is important that the temporary crown or bridge stay in
place until the final crown or bridge is placed. If the
temporary should come off early, please call the office.
After about two weeks, the crown or bridge is ready to
be fitted, adjusted, and cemented in place.
Crowns and bridges can be made of several materials. Full
gold crowns and porcelain fused to metal crowns are normally
done on the very last teeth in the mouth where strength
is most important and appearance is less important. Porcelain
fused to metal offers most of the strength of full gold,
but the esthetics of a tooth colored crown. A thin layer
of "High Noble Metal" is made to exactly fit
over the prepared tooth model, then porcelain is layered
and fired in a ceramic oven at over 2000 degrees, till
the desired shape and size is achieved. Most of The Dentist's
crowns are of this variety.
Front teeth can be restored with porcelain fused to gold,
but sometimes an all porcelain crown is used. With porcelain
fused to gold and all porcelain crowns, the color of the
porcelain is shaded to match the existing teeth, or in
some cases, lighter to cosmetically brighten the smile.
Some of the indications for a crown are:
-
A previously
filled tooth where there now exists more filling than
tooth. The existing tooth structure becomes weakened
and can no longer support the filling.
- Extensive damage by decay.
- Discolorations and compromised
esthetics.
- Fractures.
-
Root
canal - After root canal, teeth tend to become brittle
and are more apt to fracture. These teeth need to
be protected by a crown.
- Bridges are recommended
to replace one or two missing teeth. They require healthy
adjacent teeth to support the replacement teeth.
