The aim of this study was to perform a systematic review on the morphological characteristics of the skull base (flexion, anterior length and posterior length) and the concomitant development of malocclusions, by comparing differences in dimorphism, ethnicity and age.
The articles were selected by means of electronic search on BBO, MEDLINE and LILACS databases from 1966 to 2016. A qualitative evaluation of the methodologies used on the articles was also performed.
Although the literature on this topic is abundant, only 16 articles were selected for the present systematic review. The cranial base angle itself does not seem to play a significant role in the development of malocclusions. In fact, the cranial base angle is relatively stable at the ages of 5 to 15 years.
A more obtuse angle at the skull base, in association or not with a greater anterior length of the cranial base, can contribute to the development of Class II division 1 malocclusions. On the other hand, a more acute angle at the skull base can contribute to a more anterior positioning of the mandible and to the development of Class III malocclusions.
本研究旨在通过比较二态性、种族和年龄的差异，对颅底的形态特征（弯曲度、前长度和后长度）以及错牙合畸形的伴随发育进行系统评价。
通过对1966年至2016年期间BBO、MEDLINE和LILACS数据库进行电子检索来选择文章。还对文章中使用的方法进行了定性评估。
尽管关于该主题的文献很多，但本系统评价仅选择了16篇文章。颅底角本身似乎对错牙合畸形的发展没有显著作用。事实上，颅底角在5至15岁时相对稳定。
颅底角更钝，无论是否伴有颅底前长度增加，都可能导致安氏II类1分类错牙合畸形的发展。另一方面，颅底角更锐可能导致下颌骨更靠前的位置，并导致安氏III类错牙合畸形的发展。
