Major & Minor Bone Grafting
Over a period of time, the jawbone associated with missing teeth atrophies. This often leaves a condition in which there is poor quality and low quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.
Today, we 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.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee). Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.
Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites depending on the size of the defect. The skull (cranium), hip (iliac crest), and lateral knee (tibia), are common donor sites. These procedures are routinely performed in an operating room and require a hospital stay.
More on Bone Grafting
These procedures may be performed separately or together, depending upon the individual’s condition. As stated earlier, there are several areas of the body that are suitable for obtaining bone grafts. In the maxillofacial region, bone grafts can be taken from inside the mouth, in the area of the third molar region, the chin, 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.
In many cases, we can use allograft material to implement bone grafting for dental implants. This bone is prepared from human donors and used to promote the patient’s own bone to grow into the reconstruction and repair site. It is quite effective and very safe. Synthetic materials can also be used to stimulate bone formation. We can even use factors from your own blood, or proteins from bone to accelerate and promote bone formation in graft areas.
These procedures are commonly performed in our office as an outpatient surgery under IV sedation or general anesthesia. After discharge, bed rest is recommended for one day and limited physical activity for one week.
