For individuals who wish to replace missing teeth,
dental implants may be an effective long-term solution. Implants
provide greater structural support and last longer than either bridges
or dentures. Implants serve as the artificial root to which new
teeth are bonded. They are typically constructed of titanium, a
strong and safe material that effectively attaches to bone. The
procedure to insert dental implants typically involve three steps:
the implant insertion stage, osseointegration (the period of healing
for the jawbone), and the attachment of the restoration or new tooth.
Types of Implants
The most popular form of implant is the Root Implant. This type
of implant is very effective and mirrors the size and the shape
of a patient's natural tooth. Many times, this implant will be as
strong structurally as the original tooth's root. Once the dentist
applies the local anesthesia, he or she makes an incision in the
gum in order to gain access to the jawbone. The bone is then prepared
and the implant inserted into the jawbone with care and precision.
Finally, the dentist stitches the gums and, if necessary, prescribes
the appropriate medication. During the osseointegration step, which
lasts anywhere from 3 to 8 months, the jawbone firmly attaches itself
to the implant. Once osseointegration is completed, the patient
returns to the dental office where the implant is fitted with the
new tooth.
Another form of implant is the Plate Form Implant.
This implant is ideal in situations where the jaw bone is not wide
enough to properly support a Root Implant. The Plate form implant
is long and thin, unlike the Root Implant, and anchors into thin
jawbones. Once the dentist applies the local anesthesia, he or she
makes an incision in the gumline in order to gain access to the
jawbone. The bone is then prepared and the implant is inserted into
the jawbone with care and precision. The dentist then sutures the
gums and prescribes the appropriate medication. In certain cases,
Plate Implants are immediately fitted with the restoration without
waiting for the osseointegration period.
The last type of implant is the Subperiosteal Implant.
These implants are utilized when the jawbone has receded to the
point where it no longer supports a permanent implant. These implants
are placed on top of the bone and imbedded in the gums, but not
in the jawbone as with the other types of implants. The dentist
applies a local anesthesia, and makes a mold of the mouth and jawbone.
From this impression, a dental lab constructs implants to custom
fit the patient's jaw. On the second visit to the dentist, the dentist
exposes the jawbone and inserts the implant on top of it. Over the
next month the gums grow up and around the implant. This same type
of implant can sometimes be performed in a single procedure with
the use of an initial CAT scan of the gumline and jawbone.
Health Concerns
As with any cosmetic surgery, complications are rare, but can include
infection, slight damage to nerves, and mild discomfort. Although
very unlikely, infection of the gums or jawbone is a possibility
and is treated through medication and/or antibiotics. Surgery to
the upper or lower jawbone can result in mild nerve damage. Nerve
damage typically subsides in several weeks, but can persist for
longer periods of time. As the jawbone heals, patients may experience
some discomfort, which can be tempered through medication. Discomfort
subsides within 7 to 10 days.
Proper Maintenance
Although patients should always practice proper dental hygiene,
this is especially true once a dental implant has been put into
place. When teeth and gums are not properly cleaned, bacteria can
attack sensitive areas, causing the gums to swell and the jawbone
to gradually recede. Enough recession of the jawbone can weaken
dental implants and eventually necessitate their removal. Patients
should visit their dentist's office at least twice a year in order
to insure the health of your teeth and your implant. Following an
implant operation, smoking should be avoided, as it impairs the
gum and jawbone's ability to heal. Given the proper care, dental
implants should last 25 years or longer.
