The cranial base plays a key role in craniofacial growth; it helps to integrate spatially and functionally different patterns of growth in various adjoining regions of the skull such as components of the brain, the nasal and oral cavity and the pharynx. The aim of this study was to evaluate the difference in cranial base flexure between skeletal and dental Class I and Class II division 1.
MATERIALS & METHODS: Lateral cephalometric radiograph, of Class I and Class II with an average growth pattern were analyzed and compared. A total of 103 patients having class I (n=52) and class II (n=51) malocclusion, were taken from Department of Orthodontics, Rajasthan Dental College & Hospital, Jaipur. Cranial base angle (N-S-Ar) and ANB were measured on pre treatment lateral cephalograms.
In this study cranial base angle did not show statistically significant difference between the two groups studied.
In the assessment of orthodontic problems involving anteroposterior malrelationships of the jaws, the problem is usually the result of size, form and position of the jaw. The present study failed to find any differences in cranial base angle between sagittal malocclusions. How to cite this article: Agarwal A, Pandey H, Bajaj K, Pandey L.

颅底在颅面生长中起关键作用；它有助于在空间和功能上整合颅骨各个相邻区域不同的生长模式，如脑、鼻腔、口腔和咽部的组成部分。本研究的目的是评估骨骼类和牙性I类与II类1分类错牙合之间颅底弯曲度的差异。
对具有平均生长模式的I类和II类错牙合的头颅侧位X线片进行分析和比较。总共103例I类（n = 52）和II类（n = 51）错牙合患者来自斋浦尔拉贾斯坦牙科学院及医院正畸科。在治疗前的头颅侧位片上测量颅底角（N-S-Ar）和ANB。
在本研究中，所研究的两组之间颅底角没有显示出统计学上的显著差异。
在评估涉及颌骨前后关系不调的正畸问题时，问题通常是颌骨的大小、形态和位置所致。本研究未能发现矢状向错牙合之间颅底角有任何差异。如何引用本文：Agarwal A, Pandey H, Bajaj K, Pandey L. 1类和2类1分类错牙合中颅底形态的变化。《国际口腔健康杂志》2013；5(1):39 - 42。
