A Successful Dental Implant Experience
In order for dental implants to be successful there are several factors
that must be met. Patients that are not considered good candidates include
those with uncontrolled diabetes, cancer, undergoing radiation or
chemotherapy treatments, smoking, alcoholism or gum disease. It is also
important to notify your implant specialist of any prescribed, alternative
or over-the-counter medications that you are taking.
It is necessary to have sufficient bone density for the implant to graft
to properly.
Bone needs stimulation to maintain its form and density. In a
natural state , the
necessary stimulation comes from the teeth themselves. When a tooth is lost,
the lack of stimulation causes loss of bone in the area supporting the teeth. There is a 25%
decrease in width of bone during the first year after tooth loss and an
overall decrease in height over the next few years.
The more teeth lost, the more function lost. This leads to some
particularly serious aesthetic and functional problems, particularly in
people who have lost all of their teeth. And it doesn’t stop there. After
bone that supported the teeth is lost, the bone beneath it, the jawbone proper
also begins to disintegrate.
The bone must be regenerated either at the time of extraction by
grafting the bone into the sockets at the time of tooth loss
or removal or through surgical techniques by which artificial or donor bone
is grafted into the area that is deficient. This will provide the necessary bone substance for anchoring implants.
This a primary reason to consider dental implants to replace missing
teeth is the maintenance of jawbone. Only dental implants can stop the loss
of jawbone.
Placing dental implants requires a surgical procedure in which precision
channels are created in the jawbone, often using a surgical guide. The
implants are then fitted into the sites so that they are in intimate contact
with the bone. They generally require two to six months to fuse to the bone
before they can have tooth restorations attached to them to complete the
process.
There are three options for dental implants.
- If it is to replace a single tooth the implant may be placed immediately
or after a period of healing.
Then an abutment is attached
to the implant. This is a device that joins the implant to a
crown, the tooth part you see in the
mouth, the dental laboratory has
fabricated and is a match to your existing teeth. The custom crown is cemented or
screwed onto the abutment to permanently keep it in place. Once the crown is
in place it is indistinguishable from your natural teeth.
- As with single tooth replacement, when
placing multiple tooth replacements,
temporary
healing caps or abutments may be placed on multiple implants until the
healing phase is complete. After healing, the permanent abutments are
attached to the implants. They can attach to crowns or
bridgework that a dental laboratory will fabricate to match your existing
teeth. In the final step, the custom bridge, which will replace multiple
teeth, is cemented onto the abutments. The teeth have been replaced
without disturbing the healthy teeth next to them, and bone loss has been
halted.
- The third option for dental implants is if
all of your lower teeth are missing. Depending
on
the design of the removable restoration, two to six implants may be used
to support a lower denture.
If all of
your upper teeth are missing, a minimum of four implants may be used to
support an upper denture. Removable dentures are often used to replace
extensive tooth, bone and gum-tissue loss, thus
providing support for the facial skeleton, lip and cheeks. A new denture
can have attachments that snap or clip it into place on the implants or a
custom made, milled bar can be fabricated to create additional strength
and support for the restoration. Design variations are often related to
your bone density and number of implants present; your dentist will
discuss these options during your consultation. A significant advantage of
a removable denture is facilitating the cleaning of the dental implants.
Implant crowns and other prosthetic (false) tooth replacements are made to
be remarkably failsafe systems. They are removable and replaceable (only by
your dentist), so that if damage or wear necessitates replacement, this can
be accomplished without affecting the implant(s) or attachment to the bone.
Nevertheless, implants do require maintenance. It is important to
practice good daily oral hygiene, including brushing and flossing. It is also important to see your dentist and dental
hygienist. Special instruments are necessary to clean dental implants that
will not damage their metal surface beneath the gum tissues. Your dentist
will need to monitor your implants to make sure the integrity of the
osseointegration is stable, and that the implant crowns, bridgework or
dentures are functioning properly.
