| When
a fracture or a large filling weakens the
tooth, it needs repair. Your dentist may suggest
a crown, an artificial replacement of the
upper part of the tooth, to restore the function
and appearance of the damaged tooth. Crowns
can be made from different kinds of materials.
Based on location of the affected tooth, aesthetics
and cost, the right one to repair your damaged
tooth can be selected.
You
may have one or more missing teeth due to
decay or an accident. This might have lead
to changes in the way you smile, bite, and
even talk. This causes application of additional
stress on surrounding teeth to compensate
for the lost tooth. One option your dentist
may suggest for replacing the lost tooth is
with a bridge. The missing tooth is replaced
with an artificial tooth connected between
two crowns (caps), which are permanently cemented
or bonded on the adjacent teeth.
Usually,
missing teeth were restored by grinding down
the neighbouring teeth and then fabricating
custom made bridges for them. In Implant Dentistry,
this is rendered unnecessary, as a sterile
biocompatible material is inserted into the
bone, where it fuses with the bone in 3 months.
A crown is fitted onto this. This procedure
is part of the newest frontier in Dentistry
and requires special training and skill. Implants
can also be used as abutments or supports
for single crowns or bridges. In these situations
a post is attached to the implant itself.
The crown or bridge is then fitted to the
post and is held in place by either cement
or a small screw. These types of teeth are
all fully implant-supported and so bridges
may require an adequate number of implants.
The placement of these implants is also critical
for proper function and aesthetics.
