SINUS
LIFT |
| A sinus lift is a form of bone grafting
that adds bone to your upper jaw in the area of your molars and premolars.
It is done when there is not enough bone, or the sinuses are too close
to the jaw for a dental implant to be placed. The bone is added between
your jaw and the maxillary sinuses, which are on either side of your
nose. The sinus membrane has to be moved upward or lifted to make
room for the bone. |
| There are several
reasons for this: |
|
Many people who have lost teeth
in their upper jaw — particularly the back teeth, or molars
— do not have enough bone for |
|
implants to be placed. Because of the anatomy
of the skull, the back of the upper jaw has less bone than the lower
jaw. |
|
Bone may have been lost because of gum disease
|
|
Once teeth are gone, bone begins to be resorbed
(absorbed back into the body). If teeth have been missing for a long
time, there |
|
often is not enough bone left to place implants.
|
|
The maxillary sinus may be too close to the
upper jaw for implants to be placed. The shape and the size of this
sinus varies among |
|
individuals and can get larger as you age |
How
is a Sinus life done? |
| An incision will be made near the
gum tissue near your premolars and molars. Then the tissue is raise,
to expose the bone. A tiny opening is then cut in the bone, revealing
the sinus membrane. It is then moved upwards and away from the jaw.
Then several millimeters of bone are packed into the space where the
sinus was. |
| |
| The bone from the tiny opening is
then placed back and the tissue is stitched closed. The surgical site
is then left to heal for four to nine months, allowing time for the
grafted material to mesh with your bone. |
