X线头影测量,主要是测量X线头颅定位照像所得的影像,对牙颌、颅面上各标志点描绘出一定的相关线段和角度进行测量分析,从而了解牙颌、颅面硬软组织的结构,使对牙颌、颅面的检查,诊断,由表面形态而深入到内部的骨骼结构中云。几十年来,X线头影测量一直成为口腔科各专业,特别是口腔正畸、外科正畸、口腔修复等专科的临床诊断、治疗设计及研究工作的一个重要手段。传统的手工测量方法不但效率低,而且精度不高,使大样本的科研工作十分困难,也使临床诊断及治疗设计的普及受到限制。电子计算机X线头影测量系统使测量计算机化,从
X-cephalometry, mainly the measurement of X-ray cranial positioning of the image obtained from the dental, craniofacial various markers on the point of drawing a certain correlation between the line and angle measurement analysis to understand the dentures, craniofacial soft and hard tissue Structure, so that the jaw, craniofacial examination, diagnosis, from the surface morphology and deep into the internal skeleton structure of the cloud. For decades, X-cephalometry has become an important means of clinical diagnosis, treatment design and research work in dental specialty, especially oral orthodontics, orthodontics, oral repair and other specialist. The traditional manual measurement method is not only inefficient but also low in accuracy, which makes the research of large samples difficult and limits the popularization of clinical diagnosis and treatment design. Computerized X-ray cephalometric systems computerize measurements from
