Changes in the axial inclinations of upper and lower incisors after mandibular surgery in class III cases.

Cephalometric radiographs of the position of upper and lower incisors following mandibular surgery only were undertaken in 31 cases. All cases were seen before and after treatment, and after all retention had ceased. Pre-treatment records revealed some compensation of the incisor angulation for the skeletal discrepancy, and post-operatively the upper incisors proclined further and the lower incisors remained unchanged.
