[2025-09-29T19:12:30.594465] [PI reasoning] **Determining E-plane norms**

I need to tackle an orthodontic question regarding the Ricketts esthetic plane, which stretches from the nose tip to the soft tissue pogonion. For Caucasians, the norms specify that the upper lip is 4 mm behind the plane, while the lower lip is 2 mm behind. This means the answer is C: 2 mm posterior. I should provide reasoning and a citation, likely pulling from a study on cephalometric norms. I’ll look for the article "Esthetic plane line Ricketts" for evidence.
