Clinical Application of SIS for Mandibular Prognathism

Part 2. Two Cases of Orthognathic Surgery Using Multiple Regression Equation between SIS and Dentofacial Measurements

Abstract

The purpose of this study was to clarify how to use SIS for making treatment plan of orthognathic surgery cases. The efficacy of the clinical test of the multiple regression equation was investigated.
The results were as follows:
1. SIS made it possible to evaluate the soft tissue profile numerically in both pre and posttreatment.
2. Multiple regression equation made it possible to predict the severity of the soft tissue profile in posttreatment, hence these analyses were found to be useful for making treatment plan and methods.
