Micro-CT scanning and image processing of the mouse mandible. Transverse micro-CT slice of the craniofacial skeleton (A). Three-dimensional reconstruction of the whole mandible (B). The left hemimandible appeared as a relatively plane structure and was aligned parallel with the sagittal plane (C). Horizontal orientation of the mandibular plane (dashed white line) (D). Binarized image and segmentation of the mandibular bone (E). Extraction of the mandibular outline (F); the starting point of the outline (red cross) corresponded to the anterodorsal tip of the incisor alveolar bone.
