Crown
and bridgework
Crowns and bridges are fixed tooth replacements.
They are either made
entirely of ceramic or ceramic
combined with a gold-platinum alloy (porcelain
bonded onto metal).
A crown is considered if the crown of the patient’s
original tooth
is badly destroyed but the root of the
tooth is still intact. The tooth
may have to undergo
root canal treatment beforehand (see “Root
canal
treatment”). It can then also be fitted with a post
crown.
A bridge can be used to deal with gaps between
the
teeth if there is no longer any root left. The teeth
before and after
the gap (“abutment
teeth”) are
ground back and fitted with crowns – between
which the “pontics” are suspended – to recreate
a continuous
row of teeth.
As an alternative, implantology may also be used
for bridgework. The
advantage of this approach is
that it does not require abutment teeth
and these
teeth do not have to be ground back
(see “Implantology”). |
