Figure 27. A) Patient with Class II malocclusion and overbite, treated with mechanics for distalizing the entire maxillary arch, using mini-implants in the IZC. B) Force action line passes over the anterior teeth's Cr. By applying distalization force in the entire maxilla, using force parallel to occlusal plane (Gurin on the same level as the mini-implant), the anterior teeth usually keep their initial inclination (C), occurring no vertical force. D) Image illustrating case conclusion. E, F) Initial and final lateral teleradiographies.
