Where bone has already been lost following the loss of a tooth it may be necessary to do what is known as a bone graft to restore the lost bone. Modern techniques have made this procedure much more simple and effective.
Small amounts of bone are taken from other areas of the mouth and combined with artificial bone and placed in the area where bone has been lost. The transplanted bone is then covered by a membrane and left to heal. This then restores the lost bone. This can often be done at the same time as placing the dental implant.
