Clinical finite element analysis of mandibular displacement model treated with Twin-block appliance.INTRODUCTION
 Finite element analysis, a powerful numerical, analytical tool, is widely used to predict the stress and strain distribution of the craniofacial bone that orthodontics generates.


 In the Finite element analysis of the pretreatment model, the remote displacement model of the mandible was established with the sella point as the center. 
Finite element analysis
A cone-beam computed tomography scan was undertaken at pretreatment and posttreatment.
