Surface distance (SD). The SD between two 3D models can be calculated after automatic superimposition by using the iterative closest point algorithm so that the distances of all surface points from one model to the other (and vice versa) are as small as possible. Maximum SD (MaSD) is calculated as the widest distance between “meniscus A” and “meniscus B.” The mean SD (MeSD) is the mean value of all surface points between “meniscus A” and “meniscus B.” For this analysis, the Hausdorff distance, i.e., the highest values, is used
