A dental bone graft (or bone augmentation) is a surgical procedure used to repair and rebuild diseased or damaged jawbone through the transplantation of bone tissue, which facilitates bone formation and promotes wound healing. This technique is often performed as part of another dental treatment, commonly done before dental implants so that the patient has a strong and healthy bone for them to be placed.
When is a dental bone graft necessary?
Bone grafting might be needed in any of these scenarios:
Where does the bone come from?
The bone used in the procedure can come from:
- Your body (the chin, the back of the jaw, the hip, or from a leg – also called autografts).
- A deceased donor (allografts).
- An animal source (commonly from cows or pigs – also called xenografts).
- A synthetic material (ceramic, bioglass, or polymers – also called alloplastic grafts).
The dentist will decide what type of bone graft could work better in your case, depending on the size of the socket and its condition.
How long do dental bone grafts take to heal?
Recovery time can vary depending on the injury being treated and the size of the bone graft needed. As osseointegration evolves, healing can take anywhere from 4 to 9 months or longer, depending on the type of bone substitute used, the complexity of the grafting procedure, and the location of the transplant in the mouth (upper or lower jaw).
