Ridge augmentation may be indicated when tooth loss occurred some time ago, and the bone has regressed in one or more areas. The ridge of bone tissue, or arch, can be restructured with the addition of bone to achieve a more sufficient level. The procedure helps to maintain facial shape, which often suffers when bone loss occurs.
When one or more teeth are extracted, it may be necessary to preserve a portion of the ridge by adding bone. Such efforts help to mitigate the bone loss that begins as soon as a tooth is lost.
If receiving dental implants in the upper molar or premolar regions of the mouth, a sinus lift may be indicated. The need for this jaw bone grafting procedure arises when bone height is inadequate to provide a proper foundation for the implant post. Bone tissue can either be added to the floor of the maxillary sinus cavity, or the floor of the cavity can be gently raised to enable the placement of additional bone tissue.
