Fig. 5From: A novel approach to determining augmented bone volume in intraoral bone block augmentation using an intraoral scanner: an in vitro studySelection of the region of interest. a Aligned scan of full-block augmentation as a closed object (blue transparent) and ground truth (green). b Region of interest is defined using a cube object (grey transparent) which includes the augmentation with a safety margin. c Intersection of the region of interest cube from that shown in b and the augmentation surface scan is calculatedBack to article page
