If a small amount of bone is required, the bone is usually taken from another part of the mouth. This can easily be carried out in the surgery. This is either the back of the mouth (wisdom tooth area) or the chin. The donor site is selected depending on the shape of the bone needed and the amount available.
Bone grafts take in the region of 2-4 months to heal. Following the healing period, implants can then be placed into the grafted site in the normal way.
