| Over
a period of time, the jaw bone associated with missing teeth atrophies
or is reabsorbed. This often leaves a condition in which there is
poor quality and quantity of bone suitable for placement of dental
implants. In these situations, most patients are not candidates
for placement of dental implants.
We now have the ability to grow bone where needed. This not only
gives us the opportunity to place implants of proper length and
width, it also gives us a chance to restore functionality and
esthetic appearance. The bone graft procedures are referred to
as:

Sinus lift procedure
In most people, a normal sinus extends down into the upper jaw area in the back. This procedure involves elevating the sinus membrane and placing the bone graft above the upper jaw. This increases the thickness and allows implants to be placed in the back part of the upper jaw.
Ridge-augmentation
In severe cases the ridge has been reabsorbed and a bone graft
is placed to increase the ridge height and/or width.
These procedures may be performed separately or together, depending
upon the individual's condition. There are several areas of the
body which are suitable for obtaining bone grafts. In the maxillofacial
region, bone grafts can be taken from inside the mouth, in the
area of the chin or wisdom tooth region or in the upper jaw behind
the last tooth. In more extensive situations, a greater quantity
of bone can be obtained from the hip.
These surgeries are performed in the our office surgical suite
under I.V. sedation or general anesthesia. After discharge, bed
rest is recommended for one day and limited physical activity
for one week.
