were placed on the radiographic plane parallel to the cut surface at the intersection with the latter perpendicular plane (Figure 5). These digital markers correspond to the ink marked points on the cut surface for physical measurement. Corresponding digital markers were connected by a straight line extending the outer bony dimensions (Figure 6). The digital markers were then removed enabling observers to perform individual measurements on a straight digital line (Figure 7). Linear measurements on the radiographic image of the outline of the outer cortical bone were carried out with a digital volumetric analysis tool and repeated three times by 3 independent surgeons with experience in examining MDCT and CBCT at least 1 week apart.
