Bone grafting is used in oral and maxillofacial procedures to restore, augment, or regenerate bone in the jaw and facial skeleton. The underlying reason is simple: many dental and facial treatments depend on having enough healthy bone for stability and function.
Here are the main reasons it’s done:
- To support dental implants
After tooth loss, the jawbone in that area often shrinks (a process linked to bone resorption). If there isn’t enough bone, implants can’t anchor securely. Bone grafting rebuilds that volume so implants can be placed safely. - To repair bone loss from disease
Conditions like periodontal disease can destroy the bone around teeth. Grafting helps regenerate that lost bone and stabilize remaining teeth. - To reconstruct after trauma or surgery
Facial injuries, tumour removal, or cyst removal can leave defects in the jaw or face. Bone grafts restore the structure, function, and appearance of the affected area. - To improve denture fit and facial structure
When significant bone loss occurs, dentures may become loose and facial contours can change. Grafting can rebuild the ridge of the jaw, improving both function and aesthetics. - To correct developmental or anatomical defects
Some people have congenital or structural deficiencies in the jaw. Bone grafting helps reshape and strengthen these areas for better alignment and function.
The graft (which can come from your own body, a donor, animal sources, or synthetic material) acts as a scaffold. Over time, your body replaces or integrates it through a process related to bone regeneration, forming new, living bone.
