Uprighting of mesially tipped #37 and #46 with miniscrew implant and long cantilevers. The cantilevers generate molar uprighting, molar extrusion, and intrusion of the anterior teeth. Ligature between miniscrew and molar is used to control the extrusive force and the distal crown movement of each molar. Thus, the uprighting is mainly achieved by mesial root tipping. a The beginning of uprighting of #37 and #46 with long cantilevers, from the molar to the anterior teeth, and a screw mesial to the molar. b Lateral view at the initiation stage of uprighting of #46. c Lateral view at the initiation stage of uprighting of #37. d Occlusal view during the beginning stage of uprighting of #37 and #46. e Lateral view tracing of uprighting of #37 and #46 with superimposition. The black line stands for the initial position and the red line for the final position. The superimposition is applied on the panoramic radiograph and the mandibular canal the external oblique ridge and the lower border of the mandible are chosen as reference points (from Musilli et al.
