Abstract
Several vibration analysis procedures are used for determination of the levelof bone loss, status of implant stability, modal damping factor and numerous otherproperties of tissues. The detection methods of bone properties are to compare theresults of theoretical work with practical results. So, there are many options forprocessing of image data and establishing the finite element (FE) model thatdifferentiation of calculated outputs is inevitable. Uncertainty of outputs can lead tomistakes while mechanical parameters or behaviors of tissue are determined. In thisstudy, the effect of Micro-CT scanning intensity in connection with the reconstructionprocess on properties of the modal behavior of bone tissue were investigated. Resultshave shown that examined parameters have important effects on numerical values of thenatural frequencies and modal behaviors. Furthermore, it has been revealed thatnumerical values and mode shapes must be considered together for properlyunderstanding the natural vibration analysis of bone tissue.
