摘要：“最好的朋友会随着时间的流逝而脱落，牙齿也是如此。”因此，为了满足患者的社会需求和功能康复，需要更换丢失的牙齿和支撑结构。使用全口义齿进行修复治疗是一种非常常见的治疗方式；其制造过程中最大的挑战是复制正常的垂直尺寸。在不改变垂直尺寸的情况下完成治疗并获得最佳面部比例，可以避免失败。记录VD的方法有很多种。放射线头影测量作为口腔修复学的诊断工具已有五十多年的历史，许多作者，如 Ricketts (1981)、McNamara (1984) 和 Slavicek (1984) 开发并计算机化了这些技术，以关联和记录患者的 VD。然而，头影测量分析可以帮助可视化骨骼和面部比例关系。本研究使用侧位X光片进行头影测量分析，因为它可以是一种简单、非技术敏感、非侵入性和无创伤的方法来确定全口义齿患者的VD，并且还可以将生理方法（吞咽/语音）与头影测量方法进行比较以记录较低的面部高度。
Abstract “The best of friends fall out with time and so do teeth.” Thus, there is a need to replace the lost teeth and the supporting structures for the patient's social demands and functional rehabilitation. Prosthetic treatment with complete dentures is a very common treatment modality; the biggest challenge in its fabrication is to duplicate the normal vertical dimension. Failure can be avoided by completing the treatment without changing the vertical dimension and obtaining an optimal facial proportion. There are many methods to record VD. Radiographic cephalometry has been used as a diagnostic tool in Prosthodontics for over five decades and numerous authors, like Ricketts (1981), McNamara (1984) and Slavicek (1984) developed and computerized these techniques to co-relate and record VD in patients. However cephalometric analysis can help to visualize skeletal and facial proportion relation. The present study was done to use the lateral radiographs with cephalometric analysis, as it could be a simple, non-technique sensitive, non-invasive and atraumatic way to determine VD for complete denture patients and also to compare physiologic methods (swallowing/phonetics) with cephalometric method to record lower facial height.
