Figures & Tables

Figure 1.

Subspinale (A), Nasion (N), Supramentale (B) and the ANB angle was used to classify the sagittal skeletal relationship as follows: Class I (1°< ANB <4°), Class II (ANB >4°), and Class III (ANB <1°).

Figure 3.

Box plots of overjet values (mm) in the 3 categories of IOFTN [5 (n = 214), 4 (n = 164), and 1–3 (n = 25)] showing a near normal range of overjet in IOFTN 1–3 category.

Figure 4.

Box plots of ANB angles in the 3 categories of IOFTN [5 (n = 214), 4 (n = 164), and 1–3 (n = 25)] demonstrating a wide range of ANB angles in the IOFTN 1–3 category [mean (SD) = 3.44° (3.86°), 95% CI, 1.85°-5.04°, range = -4° to 9°].
