What Is Bone Grafting?
Bone grafting not only enables us to restore bone where it is lost but also gives us a chance to stimulate new bone growth in that location. This allows the placement of dental implants of accurate length and width and also provides an opportunity to restore functionality and appearance.
Types of Bone Grafting
The bone grating is of the following types:
Autogenous Bone Graft
The surgeon uses your own bones to perform this. They get them from chin, your jaw, skull, bone of the lower leg, or even hip. As the surgeon uses your own living bone for bone grafting, this helps to regrow the bone faster. Your body also does not reject the bone used for bone grafting as it is your own.
The only disadvantage of this procedure is, the surgeons take a bone from another part of your body, which takes another procedure.
Also known as allograft is a dead bone extracted from a cadaver. It is then processed using a freeze-dry method to extract the water via a vacuum. As opposed to autogenous bone, allogenic bone cannot produce new bone on its own. But it does provide a platform over which bone from the surrounding bony walls can grow to fill the defect.
It is extracted from dead bones of other species, generally a cow. The bone is refined at high temperatures to reduce immune refusal and infection. It also serves as a framework for the bone from nearby bony walls that can grow to replace the void.
Unlike autografts, both allogenic and xenogenic bone grafting does not need any second procedure to extract your own bone. But due to the absence of bone-forming properties, bone renewal may take longer than usual and give less expected results.
Bone Graft Substitutes
Many synthetic materials are available which are safe and proven alternatives, such as:
Demineralized Bone Matrix (DBM)/Demineralized Freeze-Dried Bone Allograft (DFDBA)
It is a refined allograft bone that holds collagen, proteins, and growth factors obtained from the allograft bone. This product is accessible in powder, putty, chips, or as a gel to be injected through a syringe.
Graft composites are comprised of other bone graft materials and growth factors so that advantage of a variety of materials can be attained. It has different types of blends like collagen/ceramic composite, which is very similar in nature to natural bone, DBM fused with bone marrow cells, helps in the maturation of new bone, or a collagen/ceramic/autograft composite.
Bone Morphogenetic Proteins
Bone morphogenetic proteins (BMPs) stimulate and balance bone generation and healing as they are naturally occurring proteins in the body.
Synthetic materials have their own benefits. For example, they do not require any second process to harvest bone, which reduces risk and ache.
