摘要

目的:本研究的目的是使用面部人体测量和数字2D面部摄影测量的两种方法,确定塞尔维亚民族15个颅面线性距离的值,以及它们之间的相关性,这些相关性可以预测或作为OVD的替代。材料和方法:共选择90名成年人。作为测量OVD的工具的面部距离是Sn-Gn——鼻中隔(Sn)和下巴尖(Gn)之间的距离。使用Boley Gauge(Buffalo Dental Manufacturing Co.NY,USA)进行面部人体测量。使用计算机程序DrCeph(FYI Technologies,USA)执行数字2D摄影测量面部测量。多元回归分析表明,Sn-Gn(f)依赖于ExL-ExR(f)P结论:面部人体测量和数字2D面部摄影测量的比较表明,所获得的值没有统计学显著性差异,并表明面部摄影测量可能是一种可靠的面部人体测量方法。

Comparison of Face Anthropometry and Digital 2D-Face Photogrammetry as Methods for Predicting Vertical Dimension of Occlusion.

Purpose: To determine the values of 15 craniofacial linear distances in the Serbian ethnic group using and comparing two methods of face-anthropometric and digital 2D-face-photogrammetric measurement and to determine the correlations between distances that can be predictive or can serve as proxy for occlusal vertical dimension (OVD).

Materials and methods: A total of 90 adults were selected. Facial distance as a tool to measure the OVD was measured as Sn-Gn (the distance between the septum of the nose [Sn] and the tip of the chin [Gn]). Face-anthropometric measurements were made with a Boley gauge (Buffalo Dental). Digital 2D-photogrammetric facial measurements were performed using the computer program Dr Ceph (FYI Technologies).

Results: The mean value for the distance Sn-Gn was 63.55 using face-anthropometric measurement (Sn-Gn[f]) and 63.56 using 2D-face-photogrammetic measurement (Sn-Gn[ph]) Multivariate regression analysis revealed that Sn-Gn(f) depended on ExL-ExR(f) P = .001; ZyL-ZyR(f) P = .077; N-Sn(f) P = .096; Sn-Sto(f) P = .043; and sex. Analysis also identified that Sn-Gn(ph) depended on ExL-ExR(ph) P < .001; EnL-EnR(ph) P = .029; N-Sn(ph) P = .013; Sn-Sto(ph) P = .001; and sex.

Conclusions: A comparison of facial anthropometry and digital 2D-facial photogrammetry revealed no statistical significance differences in the values obtained and showed that facial photogrammetry could be as reliable a method as facial anthropometry.
