What is a characteristic feature of Angle's Class 2 division 1 malocclusion?

• A. Deep overbite
• B. Retruded incisors
• C. Flared maxillary incisors
• D. Derived from a crowded arch

Answer: (C)

In Angle's Class 2 division 1 malocclusion, a defining characteristic is the presence of flared maxillary incisors. This occurs because the upper front teeth are typically protruded in relation to the lower front teeth. The alignment of these incisors plays a significant role in the classification of the malocclusion, as they often exhibit a forward position, which can lead to aesthetic concerns as well as functional issues during occlusion.

Flared incisors in this classification indicate that the anterior teeth are positioned more labially (toward the lips) than normal, which can lead to difficulties in achieving proper contact with the opposing teeth and can affect the overall bite and jaw function. This protrusion is a hallmark of Class 2 division 1, distinguishing it from other classifications, where the positioning of the incisors may differ significantly.

In contrast, deep overbites and retruded incisors are not specific to Angle's Class 2 division 1, as they may also be present in other dental classifications. A crowded arch typically refers to limited space in the dental arch, leading to overlapping teeth, which is not specifically characteristic of Class 2 division 1. Therefore, recognizing the feature of flared maxillary incisors is crucial for
