Photoelastic stress analysis of en masse distalizationof mandibular premolar and molar with SkeletalAnchorage System-Using isochromaticfringes and isoclinic fringes

摘要

The principal aim of this study was to photoelastically analyze the distribution and direction of stress around the roots of posterior teeth during en masse distalization under various conditions of loading. In conclusion, the photoelastic study is a very useful methodology to analyze the biomechanics of SAS.
