The 3D segmentation and reconstruction of T1 and T2 CBCT images. The maxillary teeth, maxillary alveolar bone and cranial base of T1 (a, c) and T2 (b, d) were reconstructed with various threshold values. In the U1-axis sagittal plane, the labial, palatal and total alveolar bone thicknesses were measured in three slices separated by 3 mm (S1, S2 and S3, respectively). We also assessed the U1-PP angles of T1 (e) and T2 (f)
