Figure 21. A, B) Patient with biprotrusion and anterior open bite, treated with mini-implants in the IZC and BS for distalizing mechanics. B) Curved yellow arrows represent moments generated around the maxilla and mandible's center of resistance, causing occlusal plane rotation (clockwise for the maxilla and counterclockwise for the mandible). Vertical red arrows demonstrate extrusion vectors over the incisors and intrusion vectors over the molars. In C, after four months of treatment, an improvement can be seen in the anterior vertical relationship. A clear uprighting of the incisors can be expected.
