The Distance-space was built on the mesiodistal length (MD, vertical) and buccolingual breadth (BL, horizontal) taken from each molar. The Area-space was built by estimating the occlusal areas of each molar as the A=MDxBL. The ICM-space was built by calculating the relative area size for m2 and m3 in relation to m1.
