Abstract:
Objective To construct a finite element analytical model of multiloop edgewise arch wire(MEAW),and study its mechanical characteristics.Methods Three-dimensional(3D) model of dentition-bracket-arch wire was set up in an initial graphics exchange specification(IGES) format complex by Pro/E software.The multiloop edgewise arch wire was spliced on the lower dentition.After dividing the arch wire and brackets with quarter-tetrahedron element method,the model was analyzed by ANSYS(an engineering simulation software).Results The finite element analytical model of multiloop edgewise arch wire was successfully built up.Based on the model,when multiloop edgewise arch wire was subjected to a heavy strength in certain parts(such as tooth 3,4),the anti-force strength on the other brackets(such as tooth 1,2,5,6,7) was not so heavy.The subjected strength was light and soft,especially on the first molar.Conclusion The results suggest that the finite element analytical model of multiloop edgewise arch wire built up in the experiment may be used to study the integrated mechanical characteristics,reveal the orthodontic specialty,and discuss the orthodontic mechanisms of multiloop edgewise arch wire techniques.
