What are
Implants?
Implants are metal
posts or frames that are surgically placed beneath your
gums. After placement, the implants fuse to the bone of
your jaw and act as artificial tooth roots. gums.
After placement, the implants fuse to the bone of your
jaw and act as artificial tooth roots.
What are the benefits of Implants?
One key advantage of
implants is that they fuse to the jawbone, offering
stable support to artificial teeth. Dentures, bridges or
individual teeth mounted to the implants won't slip or
shift in your mouth-an especially important benefit when
eating and speaking. This secure fit also helps
replacement teeth feel more natural than conventional
bridges or dentures.
Can
anyone have Implants?
Candidates need to
have healthy gums and adequate bone to support the
implant-and they must commit to keeping these structures
healthy. Meticulous oral hygiene and regular dental
visits are critical to the long-term success of dental
implants. Because implant placement involves more than
one oral surgery, candidates must be in overall good
health. Certain chronic diseases-like diabetes,
osteoporosis or chronic sinus problems-may interfere
with proper healing and could prevent the bone from
attaching to the implant. Long term medication use and
certain behaviors, like smoking, also may affect the
stability of the implant over time.
What are
implants made of?
The implant itself is
made of metal-usually titanium as it has proven to be
very compatible with bone and other tissues. The
surfaces of some implants are treated with a substance
that helps them adhere to the bone. Just like
conventional crowns, bridges or dentures, the
replacement teeth mounted on the implants are made of
porcelain, porcelain and metal, or polymer resin.
Are there different
types of implants? With proper patient selection, the
ADA considers two kinds of implants safe:
| |
■ endosteal;
and |
|
|
■ subperiosteal
|
Like tooth roots,
endosteal implants extend into the jawbone. A
sufficient amount of bone is required to support this
type of implant.
Afrer placement, the
gum tissue may be stitched over the implant for a period
from three to six months. During this time the bone
attaches to the implant in a process called
osseointegration. A second surgery would be needed to
attach a post to the implant. Artificial teeth then can
be attached to the posts-individually, or grouped on a
bridge or denture.
A subperiosteal
implant can be used if there is not enough bone present
to support an endosteal implant. The subperiosteal
implant is a metal frame that fits on the jawbone
beneath the gums. As the gums heal, the implant becomes
fixed to the jaw. Posts, which are attached to the
frame, protrude through the gums. As with the endosteal
implant, artificial teeth then are mounted to the posts.
Is there any way to build up the
bone in my jaw to support implants?
Some studies suggest that implant
placement can be successful in augmented bone. Bone
substitutes -either synthetic or natural-can be placed
under the gums. Over a period of about six to 12 weeks,
these materials can stimulate new bone growth.

Would I need to
see a specialist to have implants placed?
Implant placement is
not one of the dental specialties recognized by the ADA.
Implants can be
placed by general dentists or specialists-like oral and
maxillofacial surgeons, prosthodontists or periodontists.
Any dentist who places implants, however, should have
special training in the procedure. When seeking a
dentist qualified to place implants, you should ask:
| |
■
|
how much training the dentist has in this
procedure |
| |
■ |
how many implant patients he or she has treated;
|
| |
■
|
how long the dentist has been working with
implants |
What else should I know about
implants?
As with any medical or dental
procedure, implant placement is not always successful.
You and your dentist should discuss complications
related to healing factors that could influence
long-term retention of the implant.
Placing the implant and allowing
the bone to fuse with the implant will take some time.
The entire procedure can take place over a few months
and usually involves more than one surgical appointment.
Your dentist may be able to make a temporary bridge or
denture that you can use during this healing period.
Placement and adjustment of the artificial teeth also
may require more than one fitting.
Implant placement also can be
costly, and some insurance carriers do not cover this
procedure. When considering implants, you should check
with your insurer to determine how much of the cost will
be covered under your plan.
How can I tell if implants are
the right choice for me?
Talk to your dentist. He or
she is familiar with your oral health and history, and
will help you determine whether dental implants are an
option for you.
As part of a thorough evaluation,
your dentist will check the condition of your mouth, the
supporting bone in your jaws and the way your upper and
lower teeth fit together. The dentist may gather
additional information by taking dental X-rays or making
models of your teeth. This information will help
determine whether you are a good candidate for dental
implants. |
