What is Bone Grafting?
Most dental bone grafting procedures are done to restore your bone to its previous form following tooth loss, gum disease or trauma. Bone grafting may also be used to maintain bone structure after tooth extraction. You lose 30% of your bone the first year after your tooth is extracted and 10% each year after that. Bone grafts and implants are important to maintain and preserve the bones of your future.
Restoring and maintaining facial bone structure is important for several reasons. Many dental procedures, such as implant placement, require that the bone be as close to its original dimension and position as possible for optimal results. Also, the jaw and other facial bones support the skin and muscle that are responsible for our outward cosmetic appearance. Without the support of the underlying bone, our faces can look prematurely aged.
How Does Bone Grafting Work?
During the body’s normal maintenance cycle, specialized cells in the blood continually enter your tissue to remove damaged cells and replace them with new, healthy cells.
Grafting procedures place a framework of material in the areas of missing bone into which these cells can enter and start the rebuilding process. Over time, your cells will remodel the graft material into your own functioning bone.

Bone Grating Material Comes From Many Sources
Autograft bone is material that is taken from another point in the patient’s body and transplanted to the desired site. It is a good graft material since it contains the patient’s own cells, and it carries no risk of disease transmission. The chief drawbacks are that it requires a second surgical procedure, and enough harvestable bone may not be easily available.
Another source of bone graft is Allograft, which is the inorganic component of cadaver bone. The advantage of Allograft is that it does not require a second donor site, making it very convenient and safe. The disadvantage is the cost because of all the processing.
What is Allograft?
Allograft bone is material that was taken from a carefully screened organ donor. The donor material is processed to ensure safety and improve handling characteristics. Allograft bone is well documented and has an excellent safety record.
Advantages of Allograft
- Readily available
- No second surgical site
- Proven results
- Exceptional safety record
Allograft for Ridge Augmentation
Patients with missing teeth frequently experience bone loss. When too much bone is lost, a ridge augmentation is necessary to restore support for dental implants or a denture. Dr. Sowell can use allograft bone graft material to restore your jaw bone to its natural shape so it can support the restoration with either a dental implant or denture.
