Progress photographs: (A) mesial movement of the mandibular right first molar, (B) mesial marginal ridge of the mandibular right second molar is confirmed, (C) initial stage of molar occlusion using the occlusal surface of the mandibular right second molar, (D) inclination of the second molar is improved.
After retention photographs and radiographs: (A) facial photographs, (B) intraoral photographs, (C) panoramic radiograph, (D) lateral cephalometric radiograph and (E) lateral cephalometric tracing.

Superimposed tracings of lateral cephalometric radiographs at pretreatment (solid line), posttreatment (dashed line), and after retention (dotted line); right molars are traced. (A) on the sella-nasion plane at the sella, (B) on the palatal plane at ANS and (C) on the mandibular plane at Menton.
