摘要
目的 研究操作者确定标志点的可重复性 ,并获取一批恒牙初期少年的面部测量数据。方法 由同一名操作者在对 8名男性完成采像后擦去标记 ,进行重新定点测量 ,比较 14个标志点至鼻根点空间线距的前后结果。对 2 0名恒牙初期少年进行面部软组织的三维测量。结果 前后 2次定点测量的结果无统计学差异。恒牙初期少年各测量项目的性别比较中 ,17个有差异者主要集中在与下面高相关的项目上。结论 本研究所选用的标志点有明显的解剖特征 ,操作者能较好地掌握定点标准。
Objective The purpose of this article were to assess the reproducibility of the landmark locating, and to obtain some facial soft tissue measurements data of the teenagers.Methods 8 males were selected to refix the black markers by the same operator and remeasure 14 items by the system, then compare both results. Three dimensional facial morphametry was investigated in a sample of 20 teenagers at the early stage of the permanent dentition.Results No item of the remeasurement test showed statistical difference error. The sexual dimorphism was found in the measurements connecting with lower face height(Sn Pg).Conclusion It indicated that the landmarks selected in this study had biologic significance and unique definition. The result of teenager facial measurements is in accordance with growth rule. [
