Overlapping of digital images. The DICOM (Digital Imaging and Communication in Medicine) files of the obtained CT datasets, before and 1 year after grafting, are converted into a surface mesh model with digital imaging software (Mimics, Materialise, Leuven, Belgium). The two surface mesh models are then superimposed and rigidly aligned with anatomical landmarks, with the aid of software for the overlapping of digital images (Geomagic Studio, Morrisville, NC, USA). The distance between the 2 surface meshes is presented as color-coded graded figures (blue: tissue loss; yellow/orange/red: tissue apposition; green: little or no modifications) to identify zones of apposition/resorption.
