Miller Classification
Pronunciation: MIL-er klas-ih-fih-KAY-shun
System for classifying gingival recession defects based on clinical characteristics and prognosis.
Full Definition
The Miller Classification is a widely used system for categorizing gingival recession defects into four classes based on the extent of recession and the likelihood of achieving complete root coverage through periodontal surgery. Class I involves recession not extending to the mucogingival junction with no bone or soft tissue loss. Class II extends to or beyond the mucogingival junction but without bone or soft tissue loss. Class III includes recession beyond the mucogingival junction with bone or soft tissue loss, while Class IV involves circumferential bone and soft tissue loss. This classification helps predict surgical outcomes and treatment planning.
Usage
Usage note: Always specify the class number; essential for treatment planning and prognosis.
