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 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 If teeth have been missing for an extended period of time, the respective alveolar ridge (the bone which supports teeth) has been reabsorbed. This leads to a compromised situation, which cannot accommodate the placement of implants. In such cases a bone graft is needed to restore the height and the width on the alveolar ridge prior to implant placement. Traumatic injuries can lead to the loss of teeth as well as their supporting bone. This could possibly compromise the placement of implants in the injured site. The damaged or lost bone can be replaced with a bone graft, thus facilitating the esthetic and functional restoration of the injured site. 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. 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 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. These surgeries are performed in the out-patient surgical suite under I.V. sedation or general anesthesia. |
