Alveolar atrophy
In the field of dentistry, Alveolar atrophy refers to the regression of the teeth supporting jaw that occurs after the loss of a tooth. As the bone is no longer subjected to the chewing motion, regression begins to take place due to which the alveolar ridge decreases in height and width. After the occurrence of alveolar atrophy, implantation surgery is often impossible as the nerves or maxillary sinus could be damaged. In such cases, a bone augmentation surgery is to be done through which bone from another part of the patient’s body is transplanted in the osseous part of the jaw where the regression has taken place. Sometimes a fibrous ridge of tissue may also be formed when the alveolar ridge deterioration is quicker than normal. Alveolar regression and the speed of bone loss may differ from person to person depending on various factors. You can watch this video to learn more about Alveolar atrophy, its consequences and the remedies.

Thanks for sharing such an informative video! I agree with Steven about ridge preservation as an important technique since it is most useful in preserving the natural appearance of the front of the mouth. It provides appropriate support for dentures or dental bridge construction.

Ridge preservation - is a great technique, whereby a bone graft, commonly utilizing bone from a bone bank, is performed immediately after a tooth is removed (bad analogy, but kind of like filling in a pothole in the road). This retards bone resorption, preserves the ridge width and height to the bone where the tooth was and also sets a patient up for a better outcome for future treatment whether it be tooth replacement with an implant or a less desirable dental bridge. -Steven Koos DDS,MD
