Bone Grafting
Missing teeth over a period of time can cause your jawbone to atrophy, or resorb. This often results in poor quality and quantity of bone suitable for the placement of dental implants as well as long-term shifting of remaining teeth and changes to facial structure. Most patients, in these situations, are not candidates for dental implants unless they receive a bone graft. Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries.
Types of Bone Grafts
Allogenic Bone
Allogenic bone, or allograft, is dead bone harvested from a cadaver, then processed using a freeze-dry method to extract the water via a vacuum. Allogenic bone serves as a framework, or scaffold, over which bone from the surrounding bony walls can grow to fill the defect or void.
Xenogenic Bone
Xenogenic bone is derived from non-living bone of another species, usually a cow. The bone is processed at very high temperatures to avoid the potential for immune rejection and contamination. Like allogenic grafts, xenogenic grafts serve as a framework for bone from the surrounding area to grow and fill the void.
Autogenous Bone Grafts
Autogenous bone grafts, also known as autografts, are made from your own bone, taken from somewhere else in the body. The bone is most commonly harvested from your own jaw. Autogenous bone grafts are advantageous in that the graft material is your own live bone, meaning it contains living cellular elements that enhances bone growth, also eliminating the risk of your body rejecting the graft material since it comes from you.
Bone Graft Substitutes (Synthetic materials):
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
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.
Each bone grafting option has its own risks and benefits. Dr. Boghossian will determine which type of bone graft material best suited to your particular needs and will discuss this with you prior to moving forward with your procedure.
