Location of the Mandibular Canal and Thickness of the Occlusal Cortical Bone at Dental Implant Sites in the Lower Second Premolar and First Molar

Figure 2

Upper left: axial slice of the mandible with planning and orthoradial lines along the mandibular arch. Upper right: multiple orthoradial reconstructions corresponding to the orthoradial lines visible on the axial slice. Lower half: measurement of the location of the mandibular canal and the thickness of the occlusal cortical bone on the selected slice (second premolar). MC: the distance from the mandibular canal to the upper border of the mandible; CD: the distance from the mandibular canal to the buccal border of the mandible; MD: the distance from the mandibular canal to the lingual border of the mandible; TC: the thickness of the cortical bone at the occlusal side.
