摘　　要：目的为探索垂直距离与面部软硬组织标志点关联性,研究确立垂直距离的新方法。方法以100例50岁以上咬合关系稳定的患者为研究对象,使用Photoshop软件将其在治疗过程中拍摄的数码侧位片与X线侧位片重叠,测量垂直距离、软硬组织标志点间距离及相关角度,分析垂直距离与面部解剖标志点间距离及角度的相关性。结果测得垂直距离平均值为(62.83±6.11)mm,与年龄显著相关,但与性别无显著相关性。相关性检验结果显示部分面部解剖标志点间距离与垂直距离显著相关,且存在一定线性关系,其中下颌平面角是上述相关性的重要影响因素。结论面部解剖标志点对临床确定垂直距离有一定参考价值。Objective To explore the novel method to obtain the occlusal vertical dimension so as to find out the relationship between oeelusal vertical dimension and marking points of facial hard and soft tissue. Methods The study sample consisted of 100 participants, who were older than 50 and had stable ocelusal relation. We overlapped the X-ray lateral radiographs and digital lateral photos with Photo- shop, measured vertical dimension ,the lengths and angles among facial hard and soft tissue marking points, and analyzed the relationship between lengths and angles among facial anatomical marking points and occlusal vertical distances. Results The mean value of occlusal vertical dimension was （62.83 -＋ 6.11 ） mm,which was obviously related to age,but had no obvious relationship with gender. After the cor- relation test,we found that occlusal vertical dimension had strong correlations with several lengths among facial anatomical marking points, that they showed a certain linear relation,and that the mandibular plane angel was an important factor of the above mentioned correlation. Conclusions Facial anatomical marking points have certain referential value for obtaining occlusal vertical dimension clinically.
