【摘要】 目的:本研究旨在通过对成人正常人群进行Ricketts头影测量分析,为将来更深入系统的研究以及中国人正常值的提出奠定研究基础,同时也试图为VTO技术在本地区的推广应用提供一定的临床依据。方法:筛选出生于武汉市的成人正常人群33例(男性13人,平均年龄25岁,女性20人,平均年龄22岁),在自然头位(NaturalHead Posture,NHP)下获取头颅侧位片,在计算机辅助下进行Ricketts头影测量分析及统计学分析。结果:本研究得到了本地区正常人群部分样本的Ricketts分析正常值。结论:该样本中Ricketts分析结果未显示出性别差异。更多还原

【Abstract】 Objective:To investigate the dentofacial features of Chinese normal adults through Ricketts short cephalometric analysis.Methods:33 normal adults(including 13 males with mean age of 25 and 20 females with mean age of 22) were enrolled for the study.Lateral cephalometric X-rays were taken under natural head position(NHP).Computer aided methods were used for Ricketts cephalometric analysis and statistic analysis.Results:The presented study raised norms of Ricketts measurements in local area.Conclusion:The measurements showed no difference between male and female groups.更多还原
