Types of Bone Grafts and Bone Grafting Materials
What is bone grafting?
Over a period of time, the jaw bone associated with missing teeth atrophies and is reabsorbed. This often leaves a condition in which there are 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.
With bone grafting, we now have the opportunity to not only replace bone where it is missing but also the ability to promote new bone growth in that location! This not only gives us the opportunity to place implants of proper length and width, but it also gives us a chance to restore functionality and esthetic appearance.
Types of Bone Grafts
There are a few types of bone graft material ranging from autografts made from your own bone to cadaver pieces to bone-derived from non-living bone of another species, usually a cow. After a review of your medical history and discussion with you, our doctors will advise which option would be best for you.
Bone Graft Substitutes
As a substitute to using real bone, many synthetic materials are available as a safe and proven alternative, including:
Demineralized Bone Matrix (DBM)/Demineralized Freeze-Dried Bone Allograft (DFDBA)
This product is processed allograft bone, containing collagen, proteins, and growth factors that are extracted from the allograft bone. It is available in the form of powder, putty, chips, or as a gel that can be injected through a syringe.
Graft composites consist of other bone graft materials and growth factors to achieve the benefits of a variety of substances. Some combinations may include: collagen/ceramic composite, which closely resembles the composition of natural bone, DBM combined with bone marrow cells, which aid in the growth of new bone, or a collagen/ceramic/autograft composite.
Bone Morphogenetic Proteins
Bone morphogenetic proteins (BMPs) are proteins naturally produced in the body that promote and regulate bone formation and healing.
Synthetic materials also have the advantage of not requiring a second procedure to harvest bone, reducing risk and pain. Each bone grafting option has its own risks and benefits. We will determine which type of bone graft material is right for you.
