In the past, improvements in craniofacial reconstructions (CFR) methodology languished due to the lack of adequate 3D databases that were sufficiently large and appropriate for 3-dimensional shape statistics. In our study, we created the "FACE-R" database from CT records and 3D surface scans of 400 clinical patients from Hungary, providing a significantly larger sample that was available before. The uniqueness of our database is linking of two data types that makes possible to investigate the bone and skin surface of the same individual, in upright position, thus eliminating many of the gravitational effects on the face during CT scanning. We performed a preliminary geometric morphometric (GMM) study using 3D data that produces a general idea of skull and face shape correlations. The vertical position of the tip of the (soft) nose for a skull and landmarks such as rhinion need to be taken into account. Likewise, the anterior nasal spine appears to exert some influence in this regard.
过去，由于缺乏足够大且适用于三维形状统计的三维数据库，颅面重建（CFR）方法的改进停滞不前。在我们的研究中，我们从匈牙利400名临床患者的CT记录和三维表面扫描中创建了“FACE-R”数据库，提供了比以前显著更大的样本。我们数据库的独特之处在于将两种数据类型联系起来，这使得在直立位置研究同一个体的骨骼和皮肤表面成为可能，从而消除了CT扫描过程中许多对面部的重力影响。我们使用三维数据进行了一项初步的几何形态测量（GMM）研究，该研究得出了颅骨和面部形状相关性的大致概念。对于颅骨，（软）鼻尖的垂直位置以及鼻根等标志点需要考虑在内。同样，前鼻棘在这方面似乎也有一定影响。
