Class II mechanics & the development of a better device for correction
CASE PRESENTATION: A 44-year-old man presented with severe mandibular prognathism and reversed overjet before presurgical orthodontic treatment (Figs 11.57–11.61). The lateral cephalometric radiograph (Figs 11.58 and 11.59) demonstrated severe retrusion of the mandibular incisors. Therefore a presurgical decompensation was necessary at the same time as the buccal teeth were moved mesially.
