Abstract:
In orthodontic treatment, anchorage control is essential for success. A recent development, stationary anchorage (micro- implants) eliminates one of the uncertainties of orthodontic tooth movement by offering absolute control over potentially undesirable counter movements. The objective of this study was to establish a 3D finite element model for microimplant and to analyze the influence of different angulations to the long axis of the teeth (30-90°) on the biomechanical characteristics of orthodontic anchorage implant-bone interface. Results of this study showed that largest stress and deformation was seen in the cortical bone and upper region of trabecular bone. Stress and deformation increased as the angulations of the implant to the long axis of the tooth increased. As the angulation of the implant to the long axis of maxillary 1st molar increased, stress and deformation also decreased. Maximum stress and displacement were recorded when implant was placed perpendicular to the long axis of maxillary 1st molar.
