Alveolar Bone
Pronunciation: al-VEE-oh-lar
The portion of the maxilla and mandible that forms and supports the tooth sockets (alveoli), visible on dental radiographs as the surrounding osseous structures.
Full Definition
Alveolar bone is the specialized bony process of the maxilla and mandible that contains the tooth sockets and provides attachment for the periodontal ligament fibres. On dental radiographs, it is assessed for level, density, and pattern of bone loss, which are key indicators of periodontal disease. The alveolar crest — the most coronal portion of alveolar bone between adjacent teeth — is a critical reference point in bitewing and periapical radiograph interpretation. Editors should note that 'alveolar' is an adjective; 'alveolus' (singular) and 'alveoli' (plural) are the noun forms. 'Alveolar bone loss' (not 'alveolar bone lost') is the standard clinical phrasing.
Usage
Usage note: Use 'alveolar bone loss' rather than 'loss of alveolar bone' for conciseness in clinical reports. Distinguish 'alveolar bone' from 'basal bone,' which underlies the alveolar process and is not remodelled by tooth loss.
