Bone Grafting

For successful implant placement, a sufficient amount and quality of bone is essential around the site of insertion. However, if you are seeking implant treatment and you are deficient in bone volume, bone grafting will be an integral part of your implant surgery.

Today, bone-grafting procedures have become an almost integral part of implant reconstruction. Dental implant placement can be a difficult and expensive treatment option, and bone grafting procedures are often needed. In about 40% of all implantations, a regenerative procedure is required to build up bone and soft tissue. The use of bone substitutes and membranes is now one of the standard therapeutic approaches.

Bone grafting is the process of surgically placing new bone into spaces around a broken bone or bone defects. Defects are replaced with bone from the patient’s own body (autogenous bone), or an artificial, synthetic or natural alternative. The graft not only replaces missing bone, but also helps your body to re-grow its own lost bone.

In many instances, a potential implant site in the upper or lower jaw does not offer enough bone volume or quantity to accommodate a root form implant of proper size or in the proper place. This is usually a result of bone resorption that has taken place following loss of one or more teeth. Bone grafting procedures usually try to re-establish bone dimension, which was lost due to resorption.

With respect to the bone graft materials we can use, we have to differentiate between several choices. The complexity of the bone deficiency and your comfort level will influence the graft material chosen.

Autografts:

The autograft remains the gold standard to which all other materials are judged. It is basically your very own tissue, taken from a donor site and placed somewhere else in your body, into the recipient site.

Allografts:

Allograft material can also be used for dental implant treatment. An allograft is a tissue graft between individuals of the same specimen but of non-identical genetic composition. The source is usually cadaver bone, which is available in large amounts. Human bone material in the form of freeze dried bone or demineralized freeze dried bone (DFDB) has been used widely in periodontology and implant dentistry.

Xenografts:

Defined as tissue grafts between two different species (i.e. bone of bovine origin). Some have received wide acclaim and are used to provide inert framework for bone regeneration either alone or in combination with autogenous bone graft. Currently, Bio-Oss® and Bio-Gide® are widely used as dental xenograft materials.

Alloplasts:

Graft material that is synthetically derived and does not originate from humans or animals. Materials such as hydroxyapatite and similar formulations are easily used as fillers on their own or combined with autogenous bone.
