To treat facial deformation, we must start with an accurate analysis of the deformation. Orthodontists need to understand facial balance and perform treatment, accordingly. The face is roughly divided into forehead, eyes, nose, lips and chin. It is necessary to fully consider the balance of these components before starting orthodontic treatment. The participants in this study were 72 males and 50 females with normal occlusion, who met the inclusion criteria from 647 fifth-year degree students at Osaka Dental University. The mean and standard deviation of each measured value of the aesthetic triangle obtained from the cephalograms were calculated. In males, the mean (standard deviation) of NFr, NFa, NM, MC and NL were 129.97° (1.95°), 32.67° (0.90°), 132.14° (1.09°), 111.17° (2.50°) and 89.81° (2.46°), respectively. The ANB angle, interincisal angle and FMA for females were 2.48° (0.19°), 124.24° (1.41°) and 28.04° (1.41°), respectively. In females, NFr, NFa, NM, MC and NL were 136.78° (1.90°), 32.14° (0.91°), 131.32° (1.81°), 104.53° (2.66°) and 89.44° (2.51°), respectively. We concluded that these values were useful for orthodontic analysis of Japanese. (J Osaka Dent Univ 2020; 54: 153-157)
