dc.description.abstractObjective > The aim of this FEM study was to assess the effect of mechanical vibration force on miniscrews and stress distribution in cortical and trabecular bone around miniscrews. Methods > A 3D model was created using a CBCT image of a patient. Three different analyses were performed on a single model. Material properties, boundary conditions and the quality of applied forces (direction and magnitude) were defined. 150 gf, 150 gf and 30 Hz (0.2 N), 150 gf and 111 Hz (0.06 N) were applied to miniscrew from distal to mesial and from sulcus to alveolar crest direction like a power arm application. The first moment effect of force and vibration were evaluated by using Algor Fempro FEM analysis program. Von Mises and principal stress distribution on miniscrews and bone layers were evaluated by different force and vibration applications. Results > It was seen that Von Mises stress distribution on miniscrew was located on the neck region and the highest stress levels were observed in the 1st analysis (27,0159 N (mm(2))), which was only force application. The loading of the cortical bone in the proximity of the miniscrew was clearly greater with only force application rather than force and vibration application together. Maximum and minimum principle stress values gradually decreased while vibration value increased. Conclusion > It was concluded that mechanical vibration force might reduce the peri-implant loading of the bone and stress levels on the miniscrews.en_US
