Which dental segment is used to divide Class II angle malocclusion into two subdivisions?

Explanation:
The divisions of Class II malocclusion are defined by the position of the maxillary incisors. One pattern has the upper front teeth tipped forward (proclined), creating a larger overjet, while the other shows retroclined upper incisors (often with the laterals crowded), leading to a different anterior relationship. Because this anterior tooth position determines the two subdivisions, the dental segment used is the incisors—the maxillary incisors specifically. The posterior segments (canines, premolars, molars) don’t define these divisions.
