FIGURE 3.

Bland-Altman plots³³ showing the agreement between coordinates from corresponding landmarks: A and D, between landmark-based registration on the posterior teeth (R1) and landmark-based registration on the palate (R2); B and E, between landmark-based registration on the posterior teeth (R1) and registration on the palate using regions of interest (R3); C and F, between landmark-based registration on the palate (R2) and registration on the palate using regions of interest (R3). Each circle denotes the superior-inferior distance between 1 coordinate (z axis) of landmarks 3 and 4 (3-right maxillary central incisor for A, B and C; and 4-left maxillary central incisor for D, E and F) of T2 models registered by the different methods (R1, R2, R3). Solid lines denote the mean differences and the dashed lines represent the 95% limits of agreement
