Studying malocclusion during active growth period is important because this period has the maximum impact on dentofacial structures. The present study comprises of computerised cephalometric evaluation of 100 North Indian children in the age group of 9-12 years, with 50 children in normal occlusion group. The samples were segregated according to sex with 25 females and 25 males in each group. It was concluded from the study that changes or deviations in SNB, Saddle, Articular and Gonial angles are the potential indicative factors in the development of a class II malocclusion and that class II pattern is associated with short and posteriorly placed mandible in relation to the cranial base.
在生长活跃期研究错牙合畸形很重要,因为这个时期对牙颌面结构的影响最大。本研究包括对100名年龄在9至12岁的北印度儿童进行计算机头影测量评估,其中50名儿童为正常咬合组。样本按性别分类,每组有25名女性和25名男性。研究得出结论,SNB角、鞍状角、关节角和下颌角的变化或偏差是II类错牙合畸形发展的潜在指示因素,并且II类模式与相对于颅底较短且向后移位的下颌骨有关。
