In Class 2 Division 1, how are the upper incisors positioned?

• A. They are vertically aligned with the lower incisors
• B. They bite in front of the lower incisors and slope toward the lips
• C. They are retruded relative to the lower incisors
• D. They are aligned with the premolars

Answer: (B)

In Class 2 Division 1 malocclusion, the upper incisors are positioned in a way that they bite in front of the lower incisors and slope toward the lips. This characteristic describes the typical presentation of upper incisors in this classification, where there is a notable overjet due to the upper teeth protruding relative to the lower teeth. The inclination towards the lips adds to the distinct appearance associated with Class 2 Division 1, where the upper incisors are not only positioned further forward but also tend to face outward. This understanding is crucial in identifying and diagnosing different types of malocclusions, as it helps in planning appropriate orthodontic treatments. Recognizing the specific positioning of the teeth can aid dental professionals in evaluating the overall occlusion and aesthetics of a patient's dentition. The other options provide alternative descriptions that do not match the typical characteristics seen in Class 2 Division 1, highlighting the importance of accurate identification in clinical practice.
