Mandibular morphological study using Bjorks signs: Bjork seven signs for assessing hypodivergent and hyperdivergent growth patterns of mandible

The findings from the investigation suggested that significant difference in the mandibular morphology was found between the Hypodivergent and Hyperdivergent groups. Subjects with hypodivergent pattern showed inclination of condylar head to be more forwardly placed, flat inferior mandibular border, thick symphysis with a more forward inclination and more obtuse interincisal and intermolar angles. Hyperdivergent subjects exhibited backwardly placed condyle, notched inferior mandibular border, symphysis with a backward inclination and more acute interincisal and intermolar angles.
