Bone Grafting

What is Bone Grafting?


Bone grafting is a procedure where bone is used to reconstruct areas in the jaw with inadequate bone, so that implants can be placed. The source of bone can be iether patients' own bone, of artificial bone (calcium particles).

Diagram below shows the sequence of events following a tooth loss. The alveolar bone will gradually recede, leaving bone which is much smaller than before. The reduced bone height is inadequate to support a denture, and makes implant placement impossible.



This photo shows bone with inadequate width to support dental implant. A bone grafting procedure is required to augment the bone prior to implant placement.




SINUS LIFT BONE GRAFTING

Diagram 1 After an upper molar tooth is lost, the bone will resorb, causing inadequate bone height due to its proximity to the maxillary sinus. This causes inability to support a dental implant.

Diagram 2 Augmentation using a sinus lift bone grafting technique to 'rebuild' the lost bone.

Diagram 3 After bone maturation, a dental implant can be placed.
