Materials and Methods: FESA was originally introduced as a numerical form of analysis in aeronautical engineering and has the potential to obtain a computer generated mathematic model of a real object of complicated shape with its different physical material properties in order to identify the stresses and displacement. Finite element structural models of the Absoanchor implant, cortical bone and cancellous (trabecular) bone of both maxilla and mandible were generated using solid modeling software NASTRAN. In this present study three types of loads were applied on head of implant to simulate different loading conditions. The forces applied were in the range of 25-300gms in both horizontal and diagonal plane, while forces of 10-100gms were applied in vertical plane. Results: There is no bone deformation seen in this study in all the three loading conditions. Conclusion: Since there is no bone deformation for the normal range of force in all the three planes the absoanchor titanium micro-implant placed in maxilla and mandible provide stable anchorage for orthodontic force.&#13;
