Which Miller classification describes gingival recession that extends to the mucogingival junction with no interdental bone loss?

The Miller classification system is designed to categorize gingival recessions based on their extent and the condition of the underlying tissues. In this system, Class II is defined as gingival recession that extends to the mucogingival junction but does not involve any loss of interdental bone.

This classification is significant because it helps clinicians understand the severity of the gingival recession and plan appropriate treatment. In Class II, the absence of interdental bone loss indicates that while the gingival margin has significantly receded, the integrity of the bone support between teeth remains intact. This gives clinicians a more favorable prognosis for potential interventions, such as grafting procedures, compared to more advanced classifications where bone loss is present.

In summary, Class II of the Miller classification accurately describes the situation where there is gingival recession reaching the mucogingival junction without any concurrent loss of the interdental bone, underlining its specific nature in dental assessments and treatments.
