The most common cause of class II malocclusion:
Correct Answer: Growth discrepancy
Description: The class II division 2 pattern is known to have a strong familial occurrence. Peck and Peck called it a heritable entity of small teeth in well-developed jaws. According to their findings, the pattern of strong vertical posterior development of the mandible with upward and forward rotation and skeletal-facial hypo-divergence anteroposteriorly, smaller mesio-distal tooth diameters for the maxillary and mandibular incisors are characteristic pattern of heritable skeletal and tooth-size features in class II division 2 malocclusion. These findings indicate the presence of strong genetic influences in the formation of Angle’s class II division 2 overbite discrepancies.
