Bone Grafting

Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. Dr. Hagan may suggest a bone graft to prepare a more solid base for your dental implant.

Minor Bone Grafting
The most common bone grafting procedure is done to preserve the height and width of bone when a tooth is extracted in preparation for implant placement. It is very important when removing a tooth in an area of future implant placement to remove it with great care and to maintain most of the bone surrounding the tooth. The extraction should be performed by a surgeon experienced not just in removing teeth, but also in removing teeth with preservation of the surrounding bone. In addition to extraction with bone preservation, it is important to graft the socket with bone to provide a scaffold for bone growth within the socket.

Major Bone Grafting
Bone grafting is used prepare dental implant sites that have deficient volume due to previous extractions, gum recession, or injuries. The bone is either obtained from a tissue bank or your own bone is used to augment the deficient site. 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. These procedures are typically performed in the office with moderate sedation.

Major bone grafting is performed to repair large defects of the jaws. These defects may arise from a number of conditions but usually involve significant loss of jaw function. These 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. These procedures are routinely performed in an operating room and require a hospital stay.
