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 aesthetic appearance.

The bone graft procedures are referred to as:
Sinus lift procedure
This procedure involves elevating the sinus membrane and placing the bone
graft onto the sinus floor, allowing 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.
Nerve repositioning
The inferior alveolar nerve, which gives feeling to the lower lip and chin,
may need to be moved in order to make room for placement of dental implants to
the lower jaw.
These procedures may be performed separately or together, depending upon
the individual's condition. There are several areas of the body that are
suitable for attaining bone grafts. In the maxillofacial region, bone grafts
can be taken from inside the mouth, in the area of the chin or third molar
region or in the upper jaw behind the last tooth. In more extensive
situations, a greater quantity of bone can be attained from the hip
or the outer aspect of the tibia at the knee.
These surgeries are performed in 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.
