Dentures and Implants
Dentures, partial
and full, are a removable option for replacement of lost or missing teeth.
The prosthetic can be taken in and out of the mouth by the patient.
Partial dentures replace some of the teeth in your mouth and
use special attachments to help hold them in place. These attachments rest
or grip onto the existing
natural teeth or onto specially sculpted crowns called "surveyed crowns". These
attachments can be cast metal clasps or clasp-less "precision" attachments.
Porcelain or plastic teeth are attached to the partial denture in place of
the missing teeth.
Full dentures replace all of the upper or lower teeth on one or both arches.
Teeth are fabricated from porcelain, plastic or a combination of the two.
Choosing the right size, shape, contour, and shade of teeth are the keys to
giving the patient a natural and healthy appearance. Since teeth and the underlying
supporting bone work together to create the fullness and contour in a person's
face, patients who have lost all of their teeth often will have a sunken, older
appearance. Properly fabricated dentures can restore this fullness and contour,
which helps the patient maintain a younger and more desirable appearance.
Full dentures are held in place by a combination of a patient's facial musculature
and suction created by the patient's underlying bone structure. Dynamic changes
in the form of shrinking can occur in the bone and tissue under the denture
with tooth loss and age. The result could be a loose and ill-fitting denture
with decreased function.
Implants
Implants are an option for replacement of a missing tooth or teeth and often
can be made more aesthetic than conventional techniques such as bridges or
partial dentures. Implants can support dentures and prevent the bone loss
and facial aging that unsupported dentures can cause. And, implants can simply
replace full dentures for a natural appearance and greater comfort.
A prosthetic fixture (usually made of titanium) is placed into
the bone beneath the gum tissue. The implant serves as a "virtual root" onto
which a tooth or teeth can be affixed. After placement, the implant site
is allowed to heal
for four to eight months. Placement of the implant requires the use of a
local anesthetic (novocaine) and healing is usually quick with minimal discomfort.
After healing, the top portion of the implant is exposed for placement of
the final restoration.
Although they take longer to place and can be more costly than other options,
implants are considered a permanent restoration and have a very natural appearance.
Research is currently being conducted on a single-visit, one-step implant that
requires little or no healing time. Implants are considered a state-of-the-art
option for tooth replacement.
