Quantitative Prediction of Change in Chin Position in Le Fort I Impaction

ConclusionThis study draws to a conclusive finding that the movement of maxilla in the superior direction has an effect on the repositioning of the chin in the anterior and cranial directions. This has led to a formulation that 1  mm of superior impaction of maxilla results in 0.6 mm of vertical and 0.2 mm of sagittal movement of chin. This might help to have a glance of future chin position and aid in deciding the need for mandibular surgery.
