ABSTRACT
<p><b>OBJECTIVE</b>To investigate the influences of bicortical anchorage on values of natural frequencies of dental implants utilizing the 3-dimensional finite element analysis.</p><p><b>METHODS</b>Using the commercial code of Solidworks, 3-D models of a screw-shaped dental implant and a mandibular bone segment were generated. After the 3-D implant-bone complex was meshed by ABAQUS software, effects of bicortical anchorage on the buccolingual and axial first-order natural frequencies of the implant were computed.</p><p><b>RESULTS</b>Bicortical anchorage increased both the buccolingual and axial natural frequencies remarkably. As the bicortical anchorage got deeper, the frequencies correspondingly got higher.</p><p><b>CONCLUSION</b>Bicortical anchorage can increase the buccolingual and axial primary stability of dental implants.</p>
