a Illustration of changes in alveolar bone and tooth movement of the lower central incisor after complete decomposition in presurgical orthodontic treatment. The lower central incisor indicated by the dotted line presents complete decompensation; red arrow indicates fenestration; IA and IA’:the long axis of the lower central incisor before and after decompensation; IMPA and IMPA’: the angle between the long axis of the lower central incisor and the MP before and after decompensation; MA:the long axis of the mandibular symphysis; MIA: the angle between the IA and the MA. b Illustration of physiological reconstruction of alveolar bone and tooth movement of the lower central incisor after orthodontic camouflage treatment by the force transmission technique.
