This study aimed to determine how facial measurements explain the variability of dental proportions. The following measurements were obtained from 90 subjects: width and length of each maxillary anterior tooth, length of the nose, length of the upper lip, facial length (including the lengths of the facial thirds), intercanthal width, interalar width, intercommisural width while smiling, and maximum central incisor exposure while smiling. The combination of all facial measurements explained the variability of maxillary anterior teeth width/length ratios by only 20% to 38% in men and 16% to 27% in women. Within the population tested, the results suggest that the use of facial measurements for the selection of artificial denture teeth is generally inaccurate.
本研究旨在确定面部测量如何解释牙齿比例的变异性。从90名受试者身上获取了以下测量数据：每颗上颌前牙的宽度和长度、鼻子的长度、上唇的长度、面部长度（包括面部三部分的长度）、内眦间距、鼻翼间距、微笑时的口角间距，以及微笑时上颌中切牙的最大暴露量。所有面部测量值的组合仅解释了男性上颌前牙宽度/长度比变异性的20%至38%，以及女性的16%至27%。在测试人群中，结果表明，使用面部测量来选择人工假牙牙齿通常是不准确的。
