What characterizes the overjet in Class 2 Division 2 malocclusion?

• A. It is increased
• B. It is normal
• C. It is reduced
• D. It is absent

Answer: (C)

In Class 2 Division 2 malocclusion, the overjet is characterized as reduced. This condition typically involves the upper incisors being retroclined (tipped toward the tongue), which contributes to a decrease in the distance between the upper and lower incisors. Consequently, the measurement of overjet, which is the horizontal distance between the incisal edges of the upper and lower incisors, is less than normal. In this scenario, the reduction in overjet can be contrasted with other classifications of malocclusion. For instance, in Class 2 Division 1 malocclusion, the overjet is often increased due to the protrusion of the upper incisors. In a normal occlusion, the overjet is within an average range, and in Class 3 malocclusion, it is typically increased as well due to the relationship of the incisors. Therefore, understanding the characteristics of overjet in various malocclusion classes is crucial for diagnosing and implementing appropriate orthodontic treatment strategies.
