Measurement systems in the coronal zygomatic section. a Angular measurement system: frontozygomatic angle (FZA), frontoalveolar angle (FAA), and frontodental angle (FDA); rF, right fulcrum; lF, left fulcrum. b Linear measurement system: zygomaticomaxillary line (ZML), alveolar bone line (ABL), and dental line (DL). Light blue line represents the maxillary sagittal plane
