Why Consider 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. Restoring and maintaining facial bone structure is important for several reasons. Many dental procedures, such as dental 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.

Bone Grafting for Dental Implants

While the need for bone grafting has been significantly reduced, it has not been eliminated entirely. However, in most cases it is now relegated to small minimally invasive interventions that can be managed quite easily in an ambulatory (office) setting. Furthermore, while bone grafting of earlier years involved harvesting and using large quantities of the patient’s own bone (autogenous grafts). These grafts are termed xenografts and are generally comprised only of the mineral content of natural bone, have been sterilized and have had all organic material removed. A simplified explanation for the success of this form of grafting is that a bovine bone graft is placed to act as a “biological placeholder.” Initially, it mechanically prevents the collapse of the surrounding tissues, whether that is bone or soft tissue. Then, through a process called “guided tissue regeneration,” the human body is fooled biochemically to recognize the graft as natural bone and over time resorbs and replaces it with the patient’s own native bone.

What to expect with bone grafting

Your doctor may recommend a bone grafting procedure to help restore your jaw bone to a level suitable for dental implants. View illustrations of procedures below and discuss the details of your recommended procedure with your doctor.
