According to Angle's classification, the division of Class II is based on the relationship of which teeth?

• A. Canine relationship
• B. Incisors relationship
• C. First molar relationship
• D. Premolars relationship in transversal plane

Answer: (B)

The division within Class II is determined by how the front teeth meet. After establishing Class II from the molar relationship, the subdivisions look at the upper incisors in relation to the lower incisors. Specifically, it’s the maxillary incisors’ position against the mandibular incisors that defines the division: in Division I the upper incisors are typically protruded, while in Division II the upper central incisors are retroclined (often with the lateral incisors more proclined). This anterior dental relationship, not the canines or premolars, is what separates the divisions.
