Originální abstrakt
The aim of this study wasto compare mechanical performancesof bone-implant interactionwhen different material models were used in thecomputational modeling process. Specifically,homogeneous andnon-homogeneous material modelsofmandibularbone tissuewere scrutinized. Peri-implant region of the mandible was analyzedusing three variants of cancellous bone material model. The first two variantswere based on the assumption of perfect material homogeneity (with various elastic constants), the third one was assumed to be nonhomogeneousandbased onCT image data. The results indicated that the strain intensities in cancellous bone tissue wereconcentrated in the regionof implantapexregardless of the variant.Thecharacter of strains in the peri-implantregion (up to 0.1mm 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.
