Bone Grafting in Preparation for Implant Placement

Over a period of time, the jawbone associated with missing teeth atrophies or is resorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.

Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and aesthetic appearance.

We may decide to regenerate the deficient site by using a number of different techniques.
The area may be treated by using allographic (treated donor bone) Puros or xenographic (treated animal bone) Bio-Oss or by using a bone growth hormone known as Infuse. Infuse stimulates the bodies’ ability to re-grow its own bone.

Large defects may be treated by a combination of techniques. The techniques include using donor bone material or transposing the patient’s own bone from a distant donor site.

Block or Autogenous Grafting  in Preparation for Implant Placement

Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee). Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.

Major bone grafts are typically performed to repair significant defects of the jaws. These defects may arise as a result of post extraction bone loss, periodontal disease, traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites depending on the size of the defect.  Dr. DiGregorio or Dr. Anjomshoaa will graft with the goal of being able to place implants to re-establish the occlusion.
