摘要
颅底在颅面生长中起关键作用;它有助于整合空间和功能上不同的生长模式在颅骨的各个相邻区域,如大脑的组成部分,鼻腔和口腔和咽部。本研究的目的是评估骨和牙I类和II类1区颅底屈曲的差异。材料与方法:分析比较I类和II类平均生长模式的侧位头颅x线片。来自斋浦尔拉贾斯坦邦牙科学院和医院正畸科的ⅰ类(52例)和ⅱ类(51例)错牙合患者共103例。在治疗前侧位脑电图上测量颅底角(N-S-Ar)和ANB。结果:两组的颅底角无统计学差异。结论:在评估颌骨前后关系不正常的正畸问题时,问题通常是由颌骨的大小、形状和位置引起的。本研究未发现矢状面错牙合在颅底角度上有任何差异。Agarwal A, Pandey H, Bajaj K, Pandey L.ⅰ类和ⅱ类1类错颌畸形的颅底形态变化。国际口腔卫生杂志;2013;5(1): 39-42。
Changes in Cranial Base Morphology in Class I and Class II Division 1 Malocclusions.
Introduction: 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.
Results: In this study cranial base angle did not show statistically significant difference between the two groups studied.
Conclusion: 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.
