The alveolar process is also called the alveolar bone or alveolar ridge. [3] In phonetics , the term refers more specifically to the ridges on the inside of the mouth which can be felt with the tongue , either on roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
Generalized bone loss occurs most frequently as horizontal bone loss. [2] Horizontal bone loss manifests as a somewhat even degree of bone resorption so that the height of the bone in relation to the teeth has been uniformly decreased, as indicated in the radiograph to the rig defects occur adjacent to a tooth and usually in the form of a triangular area of missing bone, known as triangulation.
[2] [3] [4] Ankylosis occurs when partial root resorption is followed by repair with either cementum or dentine that unites the tooth root with the alveolar bone, usually after trauma. [5] However, root resorption does not necessarily lead to tooth ankylosis and the causes of tooth ankylosis remain uncertain to a large extent. [5]
Physiological bone resorption is an integral part of bone functioning, while the bone is constantly growing thanks to two processes — breakdown and formation of bone tissue. [23] Locally, it could be manifested in tooth eruption when the movement of a tooth follicle is followed by an active resorption of jaw bone tissue.
Postoperative bone resorption and remodeling can be reduced as the periosteal attachment to the underlying bone is maintained. The height of the ridge can be preserved while reducing the labial prominence of the alveolar ridge.
It appears only on the gingiva or on an edentulous alveolar ridge. It is more often found in the mandible rather than the maxilla, in either anterior or posterior areas. The underlying alveolar bone can be destroyed, leaving a unique appearance referred to as "cupping resorption" or "saucerization".
Bone Resorption Another tissue change that can result from wearing an overdenture is resorption of the alveolar bone. Although retention of a root prevents the alveolar bone from resorbing, at a distant site from the overdenture abutment the bone is susceptible to gradual resorption.
Alveolar osteitis usually occurs where the blood clot fails to form or is lost from the socket (i.e., the defect left in the gum when a tooth is taken out). This leaves an empty socket where bone is exposed to the oral cavity, causing a localized alveolar osteitis limited to the lamina dura (i.e., the bone which lines the socket). This specific ...
