Displacement pattern of the second molar in each direction for the 5 molar displacement protocols. a Configuration A, (b) Configuration B, (c) Configuration C, (d) Configuration D and (e) Configuration E. The color intensity correlates with the magnitude of tooth movement, with cooler hues indicating smaller movement trends and warmer hues indicating greater movement trends. Positive and negative values denote specific directions
