The aim of this study was to compare mechanical performances of bone-implant interaction when different material models were used in the computational modeling process. Specifically, homogeneous and non-homogeneous material models of mandibular bone tissue were scrutinized. Peri-implant region of the mandible was analyzed using three variants of cancellous bone material model. The first two variants were based on the assumption of perfect material homogeneity (with various elastic constants), the third one was assumed to be nonhomogeneous and based on CT image data. The results indicated that the strain intensities in cancellous bone tissue were concentrated in the region of implant apex regardless of the variant. The character of strains in the peri-implant region (up to 0.1 mm from the implant) is influenced dominantly by the geometry of the selected dental implant than by the used material model variant. To perform more credible analysis of local strains in the peri-implant region, it is preferable to adopt material model based on CT images.
