What is Bone Grafting?

Over a period of time, the jaw bone associated with missing teeth atrophies and is reabsorbed. Esto a menudo deja una condición en la que hay mala calidad y cantidad de hueso adecuado para la colocación de implantes dentales. En estas situaciones, most patients are not candidates for the placement of dental implants.

With bone grafting, we now have the opportunity to not only replace bone where it is missing, but we also have the ability to promote new bone growth in that location. Esto no solo nos da la oportunidad de colocar implantes de la longitud y el ancho adecuados., también nos da la oportunidad de restaurar la funcionalidad y la apariencia estética.

Types of Bone Grafts

Autogenous Bone Grafts

Autogenous bone grafts, also known as autografts, están hechos de tu propio hueso, taken from somewhere else in the body. The bone is typically harvested from the chin, jaw, lower leg bone, cadera, or the skull. Autogenous bone grafts are advantageous in that the graft material is your own live bone, meaning it contains living cellular elements that enhance bone growth, also eliminating the risk of your body rejecting the graft material since it comes from you.

sin embargo, one downside to the autograft is that it requires a second procedure to harvest bone from elsewhere in the body. Depending on your condition, a second procedure may not be recommended.

Allogenic Bone

Allogenic bone, or allograft, es hueso muerto cosechado de un cadáver, then processed using a freeze-dry method to extract the water via a vacuum. Unlike autogenous bone, allogenic bone cannot produce new bone on it’s own. Rather, it serves as a framework, or scaffold, over which bone from the surrounding bony walls can grow to fill the defect or void.

Xenogenic Bone

El hueso xenogénico se deriva de hueso no vivo de otra especie, 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 have an advantage of not requiring a second procedure to harvest your own bone, as with autografts. sin embargo, because these options lack autograft’s bone-forming properties, bone regeneration may take longer than with autografts, and have a less predictable outcome.

Bone Graft Substitutes

As a substitute to using real bone many synthetic materials are available as safe and proven alternatives, 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

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. Dr. Paredes determinará qué tipo de material de injerto óseo se adapta mejor a sus necesidades particulares.
