If primary Es are present move the Arc adjusted for primary dentition distal 2 mm (Fig. 17). I have found the mesial position of the 6s relative to the Midfacial Arc to vary widely from case to case. Therefore, I defer to the dental relationship of the 6s relative to one another on www.orthodontics.com Fig. 17 Spring 2023 19
