Fig. 4From: Palatal changes after treatment of functional posterior cross-bite using elastodontic appliances: a 3D imaging study using deviation analysis and surface-to-surface matching techniqueDeviation analysis and calculation of the percentage of matching between the original and speculated models of the palate detected at T0 and T1 in both test group and control group. The RGB coloured scale bar (millimetres) is shown on the right: the upper (red) and lower (blue) parts of the scale indicate the maximum positive and negative deviations. Green indicates the tolerance range, set to 0.3 mmBack to article page
