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 augment and 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 function and esthetic 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 aveolar 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.
