A patient classified as Angle's class II division 1 malocclusion is likely to have which feature?

In Angle's classification of malocclusion, class II division 1 specifically refers to a condition where the first molars have a certain positional relationship, and it is characterized by specific dental features. One of the predominant features of class II division 1 malocclusion is the proclination (forward angling) of the upper incisors. This proclination occurs as a response to the underlying skeletal and dental misalignment, which leads to the upper incisors being positioned more forward in the dental arch.

The proclined upper incisors are a notable aesthetic feature, often resulting in a more prominent appearance of the upper front teeth. This is critical as it can influence both the patient's smile and the functionality of their bite. Understanding this feature can significantly aid dental nurses in recognizing the implications of class II division 1 malocclusion on treatment planning and patient care.

In contrast, a bilateral crossbite, retroclined lower incisors, and a normal overbite do not characterize Angle's class II division 1. Instead, these features can be associated with different types of malocclusion or varying dental relationships, hence making them less relevant in the context of this specific classification.
