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, some 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 graftprocedures are:
Sinus lift procedure: The sinus membrane is elevated and bone graft is placed 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.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 attaining bone grafts. In the maxillo-facial 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.With the exception of hip grafting, these surgeries are performed in the our surgical suite under I.V. sedation. After discharge, bed rest is recommended for one day and limited physical activity for one week.
