    The distance between the FA point (midpoint of the vestibular axis of the clinical crown) and the WALA Border (anatomic structure located at the mucogingival junction of the lower maxilla) is important for determining the position of the lower maxillary teeth in Element I. These distances, lines, and reference points were described by Lawrence Andrews, who introduced the six keys to optimal occlusion, which have become a standard for evaluating the quality of occlusion in individuals. The evaluation of the vestibular anatomy of these models helped develop the straight arch appliance, which is characterized by providing brackets with three-dimensional information to perform optimal orthodontic treatment in a simpler way, without needing too many bends in the wires. Following these contributions, the philosophy of the six elements of Orofacial Harmony emerged. This analysis is important for personalized diagnostic evaluation of each patient. It is different because these analyses were conducted on people with different morphological characteristics who present different facial patterns and biotypes.
