Methods: The present study included three dimensional mandibular bones in the second premolar, ITI implant, rigid connector, and chewing force that were analyzed in ABAQUS software program by three dimensional finite element method. In this evaluation dental implant and jawbone had to exactly be modeled in the software program.
Results: There were not any modulations in the different frequencies. Increasing of frequencies from 0 to 30 HZ did not have any effect on the dental implant. Maximum stress was made in the neck of narrow neck implant and stress was decreased by the increasing of diameter.
Conclusions: Regarding to the results of this study, frequencies on the dental implant in compared with resonance frequencies had difference. Natural implant frequencies were not stimulated by chewing frequencies. So different implant failures in different frequencies were not related to implant frequencies. The best choice for each patient could be implant with maximum diameter regarding to anatomic condition.
