What does Class 3 malocclusion indicate regarding the position of the mandible?

• A. It is behind the maxilla
• B. It is aligned with the maxilla
• C. It is in front of the maxilla
• D. It is below the maxilla

Answer: (C)

Class 3 malocclusion indicates a relationship where the mandible, or lower jaw, is positioned forward relative to the maxilla, or upper jaw. This condition is often referred to as a "prognathic" bite and can lead to a variety of dental and skeletal issues. In this classification, the lower first molar is positioned more towards the front of the mouth compared to the corresponding upper molar, causing the mandible to appear more advanced than the maxilla in the overall occlusion. Understanding this relationship is crucial for dental professionals as it plays a significant role in orthodontic treatment planning and overall assessment of dental health.
