Bone augmentation is a collective term used in dental surgery to refer to a number of reinforcement surgeries that are done for jaw defects. The Onlay augmentation or grafting is a unique bone augmentation method that can be used on both the upper and lower jaw. This is done when the alveolar ridge
regression is uneven. Jaw bones are augmented by using bones from other parts of the patient’s body, bone from animals such as cattle or even synthetically manufactured bone.Transplanted human bones have the highest success rate as they heal best when compared to animal or synthetic bones.

          

Bone Augmentation is a technical term in dental surgery. This dental term describes various methods of adding bone material, in case there is a lack thereof in the jaw. Lack of bone in the jaw may have various causes. For example after the removal of a cyst a ‘localized lack of bone’ may occur.With large cysts this process may be disturbed as the resulting blood clot pulls itself together in proportion to its size. The blood clot will therefore get smaller the larger the space in the bone is. If the space is too large the blood clot will then shrink so much that it will no longer have any contact with the bone walls. Blood vessels will then no longer be able to grow out from the bone walls into the blood clot and this is a necessary requirement for bone regeneration.

A transformation of the blood clot into bone tissue is therefore no longer possible and a lack of bone results. In order to avoid these kinds of complications, where there is a big lack of bone, as shown here in the animation, this should be filled in immediately after the cyst removal with bone replacement material. The blood clot will thus not collapse into itself. That’s one example of bone augmentation.

Another example of bone augmentation would be for loss of bone due to periodontitis. Here you see a tooth isolated from the bone which has retreated. Such isolation cases respond well to reconstruction with replacement bone material. The mucous is folded to one side, bone replacement material is inserted and the wound sutured. Some weeks later the filled in area is transformed into bone. This is another example of bone augmentation, in this case to treat a tooth rather than to create a place for an implant.
