About Bone Grafting, Yorktown Heights New York
What is Bone Grafting?
Over a period of time, the jawbone associated with missing teeth atrophies is reabsorbed. This often leaves a condition in which there is 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, it also gives us a chance to restore functionality and aesthetic appearance.
Types of Bone Grafts
Autogenous Bone Grafts:
Autogenous bone grafts, also known as autografts, are made from your own bone. The bone is typically harvested from the area surrounding the site. Autogenous bone grafts are advantageous in that the graft material is live bone, meaning it contains living cellular elements that enhance bone growth.
Allogenic bone, or allograft, is bone harvested from a cadaver, then processed using a freeze-dry method to extract the water via a vacuum. The graft material is cleansed and purified and is very safe and effective. Unlike autogenous bone, allogenic bone cannot produce new bone on its own. Rather, it serves as a framework or scaffold and stimulates bone from the surrounding bony walls to grow and fill the defect or void.
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.
Both allogenic and xenogenic bone grafting are advantageous in that they do not require a second procedure to harvest your own bone, as autografts sometimes require. However, because these options lack autograft’s bone-forming properties, bone regeneration may take longer than with autografts.
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 morphogenic proteins (BMPs) are proteins naturally produced in the body that promote and regulate bone formation and healing.
Each bone grafting option has its own unique benefits. Dr. Wetzler will determine which type of bone graft material is right for you.
