A cephalometric study on changes of facial morphology in the frontal view following mandible setback surgery(bssro) in patients with skeletal class iii dentofacial deformities

ABSTRACT

0.05) postoperatively. 3. In the facial index, hard tissue decreased(0.23+/-2.21%), but soft tissue increased(2.41+/-3.46%) with statistical significance. CONCLUSION: One of the main purpose of orthognathic surgery is to achieve facial esthetics and harmony. In order to fullfill this purpose, it is important to carry out a precise presurgical treatment planning by estimating the changes of frontal profile after surgery.
