摘要
Abstract
Objective: To investigate cranial base morphology of patients with skeletal Class Ⅱ and Ⅲ malocclusion in the deciduous dentition. Method: Forty patients aged from 3 years to 5 years were divided into Class Ⅱ and Class Ⅲ group. Cephalograms were analyzed for all subjects. The mean differences between both groups were tested using Student's t-test for independent samples. Pearson's product-moment correlations were calculated between the parameters of the sagittal jaw relationship and cranial base. Result: The overall cranial base length and posterior inclined angel deceased significantly in patients with Class Ⅲ malocclusion compared with Class Ⅱ malocclusion. Significant positive correlation was detected between SNA and S-N, S-Ba,N- Ba. The value of SNB was found significant negative correlation with S-Ar,N-Ar, N-Ba, NSAr, NSBa, and positive correlation with SBa-FH. Conclusion: There is association between malocclusion in sagittal jaw relationship and cranial base morphology in the deciduous dentition, and posterior cranial base has more effects on maxillofacial morphology than anterior cranial base.关键词
