软组织X线头影近年来越来越多地受到广大正畸医生的重视,从而使X线头影测量技术更为完善。1983年美国学者Holdaway根据他多年临床经验,本着简单、直观的原则,提出了一套软组织X线头影测量方法。目前国内系统报道软组织X线头影测量研究的文章不多,本文就以西安市112名正常(牙合)儿童为研究对象,利用微机X线头影测量系统为测量统计手段,对Holdaway软组织头影测量分析法进行研究,得出其中国儿童测量项目的正常值,供临床参考。 Soft tissue X-ray in recent years more and more by the majority of orthodontists attention, so that the X-cephalometry more perfect. In 1983, according to his many years of clinical experience, American scholar Holdaway proposed a soft tissue X-cephalometry based on the principle of simplicity and intuition. At present, there are not many articles about the study of soft tissue X-ray cephalometry in our country. In this paper, 112 normal occlusion children in Xi'an were studied. Using the computerized X-ray cephalometric measurement system as measuring statistical means, Analysis method to study, come to its normal measurement of children's items in China for clinical reference.
