In patients with Class II malocclusion, what ANB angle would typically be expected?

In orthodontics, the ANB angle is a critical measure used to evaluate the relationship between the maxilla (upper jaw) and the mandible (lower jaw). In patients with Class II malocclusion, the relationship is characterized by a more significant overjet and the positional discrepancy where the maxilla is positioned further ahead relative to the mandible.

Typically, a normal ANB angle is around 2 degrees. However, in Class II malocclusion cases, due to the forward positioning of the maxilla compared to the mandible, the ANB angle tends to be larger. An ANB angle of +8 degrees indicates a significant discrepancy where the maxilla is more advanced compared to the mandible, which is consistent with the Class II classification.

This +8 degree measure suggests a more pronounced skeletal relationship, highlighting the malocclusion present in these patients. Understanding the implications of the ANB angle in different classes of malocclusion is essential for formulating appropriate treatment plans and evaluating treatment outcomes effectively.
