Single-splint two-jaw orthognathic surgery-based skeletofacial reconstruction principle. (a) Both maxilla (Le Fort I segment) and mandible (two proximal ramus segments and one distal segment) were completely osteotomized, fixed in the final occlusion (surgical occlusion splint), and moved as an integrated “maxillo-mandibular complex” (MMC) to the 3D-simulated position. To transfer the virtual simulation to actual surgery, the MMC was moved in six potential directions, including pitch, roll, and yaw rotations (blue arrows) and en-bloc linear horizontal (left or right shifts and advancements or setbacks in the antero-posterior direction) and vertical (extrusion or intrusion) movements (green arrows).
