Abstract:
Objective:To investigate influences of bicortical anchora ge on the values of natural frequency of dental implants. Methods: Using the commercial code of SolidWorks, 3-D models of a screw-shaped dental i mplant and a mandibular bone segment were generated. After the 3-D implant-bon e complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were comp uted. Results:Bicortical anchorage increased the buccolingual na tural frequencies and the axial natural frequencies of the implants by a maximu m of 13.77% and 107.40% respectively. The apical anchorage depth in the cortical bone had an insignificant effect on further increase of implant stability. Conclusion:Bicortical anchorage can increase the stability of dental implants, especially in the axial direction.
