目的：探讨牙合垂直尺寸(VDO)与面部和手部不同测量值之间的相关性，为口腔修复领域的研究提供参考。方法：对年龄在20-45岁的134名符合纳入标准的齿状样本进行横断面研究。临床上使用游标测量仪测量VDO以及面部和手部尺寸。用回归分析找出VDO与其他测量指标之间的相关性。结果：经统计学处理，受试者咬合的最小、最大和平均垂直尺寸分别为52.33、85.67和69 mm。眼外角至口角的垂直距离与VDO呈最强正相关，具有统计学意义。外眼角至外耳道、拇指尖端至食指尖端的距离与VDO的相关性最小。结论：面部测量，尤其是眼外斜角到口角的垂直距离，是一种可靠、可重复性好的测量VDO的方法，可用于临床日常测量。它消除了对主观技术的需要，例如评估生理休息位置、外观、言语、吞咽和患者舒适度，以及复杂和昂贵的X光照片和设备。
Objective: To determine the correlation between the vertical dimension of occlusion (VDO) and different facial and hand measurements, contributing in the domain of prosthodontics. Methods: A cross-sectional study was conducted on a sample of 134 dentate individuals of age group 20-45 years, who fulfilled the defined inclusion criteria. VDO along with facial and hand measurements were measured clinically usingVernier gauge. Regression analysis wasused to find the correlation between VDO and the other measurements. Results: Statistically, the minimum, maximum, and average vertical dimension of occlusion recorded for the participants were 52.33, 85.67, and 69 mm, respectively. The vertical distance from the outer canthus of the eye to the corner of mouth showed the strongest positivecorrelation with VDO, which was statistically significant. The distance from the outer canthus of the eye to the external auditory meatus and from the tip of the thumb to the tip of the index finger showed the least significant correlation with VDO. Conclusion: The use of facial measurements, particularly the vertical distance from the outer canthus of the eye to the corner of the mouth, is a reliable and reproducible technique that can be used in daily clinical practice for VDO determination. It eliminates the need for subjective techniques, such as assessment the of physiologicrest position, appearance, speech, swallowing, and patient comfort, radiographs and devices that are complex and expensive.
