Bone grafting is a surgical procedure used to repair or rebuild bone that has been lost or damaged due to trauma, disease, or tooth extraction. In dentistry, bone grafting is often performed to restore bone in the jaw before placing dental implants, ensuring there is enough bone to support the implant. It is also used to stabilize the jawbone and maintain facial structure.
Reasons for Bone Grafting in DentistryDental Implants:
Insufficient Bone Density: Bone grafting is commonly needed when a patient does not have enough bone in the jaw to securely hold a dental implant. This may occur due to bone loss after tooth extraction, periodontal disease, or long-term tooth loss.Preservation of the Jawbone:
After Tooth Extraction: Bone grafts are sometimes placed immediately after tooth extraction to preserve the socket and prevent bone loss, making future implant placement easier.Sinus Lift:
In the upper jaw, particularly in the area of the molars and premolars, a sinus lift (a type of bone grafting procedure) might be necessary to add bone below the sinus membrane when the natural bone has resorbed.Repair of Bone Defects:
Bone grafts can be used to repair defects in the jawbone caused by trauma, surgery, or congenital conditions.
