Three-dimensional dynamic evaluation of facial soft tissue changes following anterior traction in growing Angle Class III malocclusion patients. J Han, Q Li, L Wang, J Zhang, B Liu, H Zhan, J Liu, K Qi.
By adopting the 3dMD dynamic system, we captured, for the first time, a significant increase in RMS values during key facial movements, including smile lips open, lip purse, and cheek puff, following traction treatment. As an orthopedic treatment, anterior traction provides a structural basis for the forward development of the maxilla by stimulating the patient’s own growth potential and promoting bone suture reconstruction.
