Dental Injerto de Hueso en Falls Church, Virginia

What is Bone Grafting?

Durante un período de tiempo, la mandíbula asociada con los dientes que faltan se atrofia o se reabsorbe. Esto deja a menudo una condición en la que no es de mala calidad y cantidad de hueso adecuado para la colocación de implantes dentales. En estas situaciones, la mayoría de los pacientes no son candidatos para la colocación de implantes dentales.

Hoy, tenemos la capacidad de hacer crecer hueso donde sea necesario. Esto no sólo nos da la oportunidad de colocar implantes de longitud y anchura adecuada, sino que también nos da la oportunidad de restaurar la funcionalidad y apariencia estética.

 

Mayor Injerto de Hueso

El injerto óseo puede reparar sitios de implante con la estructura ósea inadecuada debido a las extracciones anteriores, enfermedad de las encías o lesiones. El hueso es o bien obtenerse a partir de un banco de tejidos o en su propio hueso se toma de la mandíbula, la cadera o la tibia (debajo de la rodilla). injertos óseos del seno también se realizan para reemplazar el hueso en el maxilar superior posterior. Adicionalmente, membranas especiales se pueden utilizar que disolver debajo de la encía y proteger el injerto de hueso y estimular la regeneración ósea. Esto se llama la regeneración ósea guiada o regeneración tisular guiada.

injertos óseos principales se realizan normalmente para reparar los defectos de los maxilares. Estos defectos pueden surgir como consecuencia de las lesiones traumáticas, cirugía de tumores, o defectos congénitos. Los defectos grandes se reparan con el paciente y rsquo; s propio hueso. Este hueso se cosecha de un número de sitios diferentes, dependiendo del tamaño del defecto. La calavera (cráneo), cadera (cresta ilíaca), y lateral de la rodilla (tibia), son sitios comunes. Estos procedimientos se realizan de forma rutinaria en una sala de operaciones y requieren una hospitalización.

Types of Bone Grafts

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 typically harvested from the chin, jaw, lower leg bone, cadera, or the skull. Autogenous bone grafts are advantageous in that the graft material is live bone, meaning it contains living cellular elements that enhance bone growth.

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 in your best interest.

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. 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:

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 with autografts. sin embargo, because these options lack autograft’s bone-forming properties, bone regeneration may take longer than with autografts, with a less predictable outcome.

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:

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. Our surgeons will determine which type of bone graft material is right for you.
