Numbers of Beauty: An Innovative Aesthetic Analysis for Orthognathic Surgery Treatment Planning

The aim of this study was to validate a new aesthetic analysis and establish the sagittal position of the maxilla on an ideal group of\r\nreference.We want to demonstrate the usefulness of these findings in the treatment planning of patients undergoing orthognathic\r\nsurgery. We took a reference group of 81 Italian women participating in a national beauty contest in 2011 on which we performed\r\nArnett’s soft tissues cephalometric analysis and our new “Vertical Planning Line” analysis.We used the ideal values to elaborate the\r\nsurgical treatment planning of a second group of 60 consecutive female patients affected by skeletal class III malocclusion. Finally\r\nwe compared both pre- and postoperative pictures with the reference values of the ideal group. The ideal group of reference does\r\nnot perfectly fit in Arnett’s proposed norms. From the descriptive statistical comparison of the patients’ values before and after\r\northognathic surgery with the reference values we observed how all parameters considered got closer to the ideal population. We\r\nconsider our “Vertical Planning Line” a useful help for orthodontist and surgeon in the treatment planning of patients with skeletal\r\nmalocclusions, in combination with the clinical facial examination and the classical cephalometric analysis of bone structures.
