Attached Gingiva
The firm, stippled gingival tissue bound to the underlying periosteum and alveolar bone, extending from the free gingival groove to the mucogingival junction.
Full Definition
Attached gingiva is the portion of the masticatory mucosa that is tightly bound to the periosteum of the alveolar process and the cementum of the root. Its width is measured from the mucogingival junction to the base of the gingival sulcus (or periodontal pocket), and varies significantly by tooth type and individual. A minimum width of attached gingiva is considered important for maintaining periodontal health, particularly around dental implants and teeth subject to high frenal pull. The characteristic orange-peel stippling seen on attached gingiva in health is attributed to the interlocking of epithelial ridges and connective tissue papillae. Editors should be aware that 'width of attached gingiva' and 'width of keratinised gingiva' are related but distinct measurements.
Usage
Usage note: Distinguish carefully from 'keratinised gingiva,' which also includes the free (marginal) gingiva. The two terms are frequently confused in clinical documentation.
