目的 研究女性单侧上颌唇侧错位尖牙与矢状骨面型之间的关系,探讨女性上颌单侧唇侧错位尖牙患者的牙颌面形态特征。 方法 选出女性患者上颌单侧尖牙唇侧错位30例进行头颅定位侧位片的定点测量分析,将所测项目值与正常值比较。采用SPSS17.0对数据进行
t检验。结果 测量项目中,SNA、A＇-Ptm＇、ANS-Ptm、Wits值、 L1-NB角中均小于正常值,而U1-SN角、U1-NA角大于正常值,差异有统计学意义(
P<0.05)。结论 女性上颌单侧唇侧错位尖牙使上颌基骨矢状向发育不足,有Ⅲ类骨面型倾向。
Abstract
Objective: To investigate the relationship between unilateral maxillary labial malposed canines and sagittal facial type in female, and evaluate the dentofacial morphological characteristics of female with unilateral maxillary labial malposed canines.Methods: A total of 30 cases of unilateral maxillary labial malposed canines in female patients were selected, and their cephalometric films were measured and analyzed.SPSS17.0 was applied for
ttest.Results: SNA, A＇-Ptm＇,ANS-Ptm, Wits and L1-NB were smaller than the normal value, U1-NA and U1-NA were greater than the normal value in groups. Conclusion: The unilateral maxillary labial malposed canines of female might result in short maxillary basal bone, and tends to be Class Ⅲ facial type.
