Measurement method at measurement point 4. (a) Customised axial: Adjust the axis to appear perpendicular to the buccal cortical bone. (b) Customised sagittal: Adjust the axis to appear horizontal to the mandible’s inferior border. (c) Customised coronal: Measurements are taken with a digital ruler 5–7 mm above the inferior margin of the mandible (blue line), specifying the profile curve as in the path of the bicortical screw placement (yellow line). The full width at half maximum is used to measure the buccolingual thickness of the mandible.
