The prevalence of edentulism is pandemic and people resort to complete dentures for the restoration of missing teeth and esthetics. However, the determination of the correct occlusal vertical dimensions (OVD) constitutes to play an important role in overall patient satisfaction. The objective of this study was to apply anthropometric methods to correlate the length of index finger (2D) to measure the OVD from base of the nose to the base of the chin (Sn-Me) and to assess satisfaction by comparing both the methods. A total of 80 edentulous patients were randomized and controlled for this trial into experimental and control groups. A correlation was found between Sn-Me and finger measurements, dentures' satisfaction was assessed after a 1-week follow-up and marked according to the Visual Analog Scale. Our findings established that finger measurements are greater among males, and in both genders, positive, and statistically significant correlations exist between the facial and finger length measurements. Moreover, 97.0% patients from experimental group were satisfied with the use of complete dentures through the new anthropometric method. Hence measuring the length of index finger can be an adjunct method for the restoration of OVD and is a relatively time-effective and simple method with a satisfactory follow-up.Trial registration: ID: NCT05153213 ( https://clinicaltrials.gov/ct2/show/NCT05153213 ).
无牙颌的流行是全球性的，人们求助于全口义齿来修复缺失的牙齿和美观。然而，确定正确的正中颌垂直距离（OVD）对于整体患者满意度起着重要作用。本研究旨在应用人体测量学方法将食指长度（2D）与从鼻底到颏底（Sn-Me）的 OVD 测量值相关联，并通过比较两种方法来评估满意度。共有 80 名无牙颌患者被随机分为实验组和对照组进行试验。发现 Sn-Me 与手指测量值之间存在相关性，在 1 周随访后评估义齿满意度，并根据视觉模拟量表进行标记。我们的研究结果表明，男性的手指测量值更大，并且在两种性别中，面部和手指长度测量值之间存在正相关且具有统计学意义。此外，实验组 97.0%的患者对使用新的人体测量学方法修复 OVD 非常满意。因此，测量食指长度可以作为 OVD 修复的辅助方法，是一种相对省时、简单且随访满意度高的方法。试验注册：ID：NCT05153213（https://clinicaltrials.gov/ct2/show/NCT05153213）。
