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 relationship between the vertical distance and facial and soft tissue marks, and to study a new method of establishing vertical distance. Methods 100 cases of patients over 50 years old with stable occlusion were selected as research objects. The digital lateral radiographs taken during the treatment were overlapped with the X-ray lateral radiographs by Photoshop software. The vertical distance, the distance between the soft and hard tissue markers And related angles, analyze the vertical distance and facial anatomical landmarks distance and angle of the correlation. Results The mean vertical distance was (62.83 ± 6.11) mm, which was significantly related to age but not significantly related to gender. Correlation test results showed that the distance between facial anatomical landmarks was significantly related to the vertical distance of , and there was a certain linear relationship between them. The mandibular plane angle was the important influencing factor of the above correlation. Conclusion Facial anatomical landmarks have certain reference value for clinical determination of vertical distance.
