Flow Diagram Dolphin Method. T1 and T2 CBCT images are approximated using 4 landmarks located at the right and left frontozygomatic sutures and the right and left mental foramen and superimposed on the cranial base. Then the slice views (axial, sagittal and coronal) are used to confirm the precision of Dolphin 3D superimposition. Once this step is completed, the registered post-treatment scans are exported as DICOM files and opened in ITK-Snap software to convert them into GIPL format. After placing the defined landmarks to pre and post-treatment images, 3D surface models were created using 3D Slicer. 3D linear distances between T1 and T2 of corresponding landmarks are then quantified and color-coded maps are created
