[Influence of bicortical anchorage on the natural frequencies of dental implant].
OBJECTIVE
To investigate the influences of bicortical anchorage on values of natural frequencies of dental implants utilizing the 3-dimensional finite element analysis.


METHODS
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.


RESULTS
Bicortical anchorage increased both the buccolingual and axial natural frequencies remarkably. As the bicortical anchorage got deeper, the frequencies correspondingly got higher.


CONCLUSIONS
Bicortical anchorage can increase the buccolingual and axial primary stability of dental implants.
