Specify the aetiology of Class II/2 Angle malocclusion?

• A. Respiratory disorders
• B. Infantile swallowing
• C. Premature loss of milk teeth
• D. Hereditary nature of the pathology

Answer: (D)

The main factor driving Class II Division 2 malocclusion is genetic predisposition. This pattern—often showing a tendency for retroclined upper front teeth with a deep bite and a relatively retrusive mandible—frequently runs in families, indicating inheritance of the skeletal and dental traits that produce this type of occlusion. Environmental influences can modulate expression or severity, but they are not the primary cause of Class II/2. Respiratory issues, infantile swallowing patterns, or premature loss of deciduous teeth may affect development in some cases, yet they do not establish the characteristic inheritance seen with this malocclusion.
