Bone Grafting

There is variety of bone graft choices obtainable for patients who got to reverse jaw bone loss in preparation for dental implants.

Bone graft is that the replacement or augmentation of the portion of the jaw bone that anchors the teeth. it is an operation that is typically done to reverse the loss or reabsorption of bone which will have occurred owing to tooth loss, trauma, malady or ill-fitting dentures, and to reconstruct the bone structure at a lower place the gums in preparation for the position of dental implants or alternative tooth replacements

When bone graft is planted within the jaw, it does not simply merely fill a void within the bone; it should additionally facilitate promote new bone growth in this location. once triple-crown, bone affixation will restore each the peak and breadth of your jaw bone.

There are various bone graft choices and that they take issue in however they assist promote bone formation. They include:

Autogenous Bone Grafts: Also referred to as autografts, these styles of grafts are made up of the patient’s own bone, harvested from elsewhere within the body.

Autogenous bone graft has historically been thought of the “gold standard” as a graft material as a result of its “live bone” complete with the living cellular components that enhance bone growth. These embody osteogenesis (bone formation from cells), osteoconduction (bone formation via migration upon a scaffold) and osteoinduction, which direct cells to make new bone).

A potential drawback of autogenic bone attachment, however, is that it involves a second procedure to reap the bone, which can be painful and not in some patients’ best interest, betting on their condition. It additionally might not be a viable possibility in instances wherever the patient’s overall bone quality and/or density is poor, or once an outsized volume of graft material is needed.

Allogeneic Bone: Allogeneic bone, conjointly known as homograft, is bone derived from a genetically unrelated member of constant species. It’s generally non-vital (dead) bone harvested from remains, and then processed employing a lyophilization methodology that extracts all the water via a vacuum.

Allogeneic bone cannot manufacture new bone on its own – it’s neither osteogenic (like autograft) nor osteoinductive (like BMP). Rather, its primary mechanism of action is that it’s osteoconductive, and is a framework or scaffold over that bone from the encircling bony walls will grow to fill the defect or void.

Xenogenic Bone: Similar to allogeneic bone, xenogenic bone is non-vital bone derivative from another species, sometimes a cow. As a result of the potential for immune rejection and contamination by infectious agent proteins is higher in bovine bone than in human dead body bone, transplant material is processed at terribly high temperatures. Xenograft’s mechanism of action is comparable thereto of graft – it is an osteoconductive background on that bone from the encircling space will grow to fill the void.

These affixation choices square measure most popular by several patients and dental professionals alike as a result of they eliminate the doubtless painful second gathering procedure. However, as a result of graft and transplant lack autograft’s bone forming properties, bone regeneration might take somewhat longer than it will once mistreatment the patient’s own bone and therefore the outcome could also be less foreseeable.

Bone Graft Substitutes: Bone graft substitutes are commercially produced synthetic products that have many of the same bone forming properties as human bone, and are a safe and proven alternative to autograft and allograft.

One of the advantages of using a bone graft substitute instead of autogenous bone is that it eliminates the need to harvest the patient’s own bone, thus potentially reducing the risk and pain associated with the harvest procedure.

Some bone graft alternatives include:

Demineralized Freeze-Dried Bone Allograft (DFDBA): a product of processed homograft bone, DBM/DFDBA contains scleroprotein, proteins and growth factors that square measure extracted from the homograft bone. it’s on the market within the style of a powder, crushed granules, putty, chips or as a gel that may be injected through a syringe.

Ceramics: Ceramics also are used as a substitute for bone grafts, and are accessible in several forms like porous and mesh. Though ceramics might offer a framework for bone growth, they contain none of the natural proteins that influence bone growth and will be related to inflammation in some patients

Bone Morphogenetic Proteins: These proteins are produced in the body naturally, which regulates bone healing and formation.

Graft Composites: Graft composites use combos of different bone affixation materials and/or bone growth factors to realize the advantages of a spread of gear. Typical combos in use nowadays include: a collagen/ceramic composite, which closely reproduces the composition of natural bone; DBM combined with bone marrow cells, that aid within the growth of latest bone and a collagen/ceramic/autograft composite.
