Bone Grafting in Dentistry

Dental bone grafting is a surgical procedure that replaces missing bone in the jaw to create a stable foundation for dental implants or to restore bone lost due to periodontal disease, trauma, or tooth extraction. The grafting material stimulates new bone growth through osteoconduction, osteoinduction, or osteogenesis depending on the material type. Four main categories of bone graft materials are used: autografts from the patient's own body, allografts from human donors, xenografts from animal sources (typically bovine), and synthetic materials such as calcium phosphate or hydroxyapatite. Each has specific advantages and indications based on the defect size and location. The healing period for bone grafts typically ranges from three to nine months, during which the graft material gradually transforms into the patient's own bone. Advanced techniques such as ridge augmentation and sinus lifts address specific anatomical challenges. Growth factors like platelet-rich plasma and bone morphogenetic proteins can accelerate healing and improve outcomes.
