For years, physicians have used various types of implants to replace missing parts such as hip and
shoulder joints. Today, dentists can replace missing teeth in much the same way. A dental implant is
simply a metal or ceramic device that replaces the root of the natural tooth. After an implant is placed
into underlying bone, artificial teeth are attached to it, enabling normal function.
Whether an implant is right for you depends on where the implant will be placed, the kind and amount
of bone available in the jaw, and the design of tooth or teeth that will be placed on the implant.
Implants are not the right restorative choice for every patient. First, you must have enough healthy
jawbone to support an implant, or you may require a bone graft. Patients with medical conditions
such as diabetes and cancer, or with conditions affecting their ability to use hands and arms, are
usually not good implant candidates. Likewise, it is not suitable for smokers, and patients who are
not committed to thorough home care.
Implants are not a quick fix. Treatment requires several months. First your mouth will be examined
thoroughly, and x-rays of your head, jaw and teeth will be taken. Impressions or molds of your teeth
and jaws will also be made so that the dentist can determine exactly where the implant should be
placed. You may be required to undergo blood tests as well as a physical examination, to determine
your overall health status.
The surgical phase of implant treatments is typically performed in two stages, although it can be
done in one stage. The surgery can be performed under local anesthesia in the dentist’s office or
under intravenous anesthesia. Within a few days, the gums should return to normal, and you will be
able to resume most of your routine activities.
The surgical placement time per implant is approximately one hour depending on the complexity of the
procedure. Healing is approximately three months in the lower jaw and six months in the upper jaw while
the implant permanently attaches to the bone. After integration, implants can be restored with a crown
or bridge.
Poor oral hygiene is a big reason why some implants fail. It is important to floss and brush around
the fixtures at least twice a day, without metal objects. Your dentist will give you specific instructions
on how to care for your new implants. Additional cleanings of up to four times per year may be necessary
to ensure that you retain healthy gums. You will need an examination by a restorative dentist at
least once a year.
Implant therapy has been tremendously beneficial to patients who have been unable to wear, or do
not want to wear, removable or fixed bridges. Once successfully integrated into the bone, the implant
can last indefinitely, barring infection. The life expectancy of the restoration will be the same
as a regular crown or a bridge.
