A high mandibular plane angle (steep, hyperdivergent growth pattern) is most commonly associated with which malocclusion?
Show answer and explanation
Correct answer: D. Anterior open bite
- A. Class III relates to sagittal jaw relationship rather than the vertical growth pattern.
- B. Posterior crossbite reflects transverse discrepancy, independent of the vertical dimension.
- C. Deep bite is associated with a LOW mandibular plane angle (brachyfacial, horizontal growth pattern).
- D. Correct. Backward/downward mandibular rotation increases the mandibular plane angle and the anterior face height, which characteristically produces an anterior open bite (dolichofacial pattern).
