📕 Antegonial notch is present at the lower border of mandible. Here we present the study of cranio facial morphology depending on the Antegonial notch depth that helps in the orthodontic treatment as well as predicting the cranio facial morphology of the growing child.This also shows the correlation between notch depth and craniofacial morphology. This work will be of great value for academicians, students and clinicians.
