Dental
Health: Dentures
A denture is a removable replacement for missing teeth and surrounding
tissues. Two types of dentures are available – complete and
partial dentures. Complete dentures are used when all the teeth
are missing, while partial dentures are used when some natural teeth
remain.
Complete Dentures
Complete dentures can be either "conventional" or "immediate."
Made after the teeth have been removed and the gum tissue has begun
to heal, a conventional denture is ready for placement in the mouth
about 8 to 12 weeks after the teeth have been removed.
Unlike conventional dentures, immediate dentures are made in advance
and can be positioned as soon as the teeth are removed. As a result,
the wearer does not have to be without teeth during the healing
period. However, bones and gums shrink over time, especially during
the healing period following tooth removal. Therefore a disadvantage
of immediate dentures compared with conventional dentures is that
they require more adjustments to fit properly during the healing
process and generally should only be considered a temporary solution
until conventional dentures can be made.
Partial Dentures
A removable partial denture or bridge usually consists of replacement
teeth attached to a pink or gum-colored plastic base, which is connected
by metal framework that holds the denture in place in the mouth.
Partial dentures are used when one or more natural teeth remain
in the upper or lower jaw. A fixed (permanent) bridge replaces one
or more teeth by placing crowns on the teeth on either side of the
space and attaching artificial teeth to them. This "bridge"
is then cemented into place. Not only does a partial denture fill
in the spaces created by missing teeth, it prevents other teeth
from changing position. A precision partial denture is removable
and has internal attachments rather than clasps that attach to the
adjacent crowns. This is a more natural-looking appliance.
Are There Alternatives to Dentures?
Yes, dental implants can be used to support permanently cemented
bridges, eliminating the need for a denture. The cost is usually
greater, but the implants and bridges more closely resemble the
feel of real teeth. Dental implants are becoming the alternative
to dentures. |
