A three-dimensional Finite element analysis for initial stress of maxillary incisors during activation of upper utility arch wire / 대한치과교정학회지

ABSTRACT

The purpose of this study was to find the difference of stress distribution of initial compressive and tensile stress when anterior section of uppor utility arch was activated crown lingual torque of 5degrees, 10degrees, 15degrees through three dimensional finitc element analysis. For this study, the finite element model of upper central and lateral incisors 1st, and 2nd, premolars and 1st. molars and each periodontal membrance and upper utility arch were made. From the solutions of ANSYS the followings were obtained.
