目的：本研究的目的是比较临床面部软组织测量与面部石膏模型，三维扫描面部石膏模型，三维数字摄影测量图像，三维激光扫描仪images.Materials：三维面部图像的15名成人获得立体摄影测量和三维激光扫描仪。使用硅胶印模获得受试者的面部模型并进行扫描。地标被标记的主题和石膏模型，数字化的三维模型，并在模拟12.0软件（Materialise的交互式医学图像控制系统，鲁汶，比利时）测量。结果：没有统计学显着差异，发现所有的三维测量方法之间的口宽，人中位高，鼻宽。临床测量结果与石膏模型测量结果的比较显示，临床测量的人中宽度、鼻尖突出度、右唇和上唇高度比石膏模型测量的宽和长。比较临床测量的激光扫描和立体摄影测量模型的测量结果显示，人中侧面和唇的高度和人中宽度的方法之间有显着差异。当激光扫描和立体摄影测量进行了比较，显着差异，观察在嘴唇和鼻孔heights.Conclusions：面部印象可能是有问题的，由于抑郁症造成的印象材料，特别是在鼻尖。激光扫描不够灵敏，无法看到更深的压痕，如鼻孔。立体摄影测量是有前途的三维面部测量，甚至会更好的颜色识别之间的粘膜皮肤交界处的嘴唇区域实现。
Aim: The aim of this study was to compare the clinical facial soft tissue measurements with the measurements of facial plaster cast, three-dimensional scanned facial plaster cast, 3-dimensional digital photogrammetrical images, and three-dimensional laser scanner images.Materials and Methods: Three-dimensional facial images of 15 adults were obtained with stereophotogrammetry and a three-dimensional laser scanner. Facial models of subjects were obtained using silicone impression and were scanned. Landmarks were marked on the subjects and plaster casts, digitized on three-dimensional models, and measured in Mimics 12.0 software (Materialise's Interactive Medical Image Control System, Leuven, Belgium).Results: No statistically significant differences were found between all three-dimensional measurement methods in mouth width, philtrum median height, and nasal width. Comparison of clinical measurements with facial plaster cast measurements revealed that philtral width, nasal tip protrusion, and right lip and nostril heights were wider and longer in clinical measurements than in facial plaster cast measurements. Comparison of clinical measurements to the laser scanned and stereophotogrammetric model measurements revealed that philtrum lateral and lip heights and philtral width were significantly different between methods. When laser scanned and stereophotogrammetric measurements were compared, significant differences were observed in lip and nostril heights.Conclusions: Facial impression may be problematic owing to the depression caused by the impression material especially on the tip of the nose. Laser scanning is not sensitive enough to visualize the deeper indentations such as nostrils. Stereophotogrammetry is promising for three-dimensional facial measurements and even will be better when color identification between mucocutaneous junctions of the lip region is achieved.
