Stress Distribution Under High-pull Extraoral Chin Cup TractionA photoelastic study
Photoelastic stress analysis of a three-dimensional model of craniofacial structures is used to identify the areas of ultimate stress distribution under high-pull chin cup traction. Greatest concentrations outside the dentition are in the retromolar area and condylar process of the mandible.Abstract
