Which feature is used to distinguish Class II malocclusion subdivisions in the context of the material?

Explanation:
The feature used to distinguish Class II malocclusion subdivisions is the position and inclination of the upper front teeth, especially the maxillary incisors. In Division 1, the upper incisors are proclined, producing a noticeable overjet. In Division 2, the upper central incisors tend to be retroclined (often with the laterals contributing to a deep bite). This anterior-tooth variation sets the subdivisions apart, while the relationships of canines, premolars, or molars don’t define the division itself.
