Stress-strain analysis of dental implant inserted in different mandibles

This thesis deals with a problem in the field of dental implantology, namely the mechanical interaction between the dental implant and the bone tissue of the mandible. This interaction is affected by the shape and density of the bone tissues. A review of studies dealing with mechanical stresses at the bone-implant interface is carried out. The obtained information were further used in the analysis of bone tissue density and in the strain-stress analysis of three geometrically different jaws with an implant placed in the first molar region. Bone density was evaluated based on information obtained from CT scans of the individual jaws. For evaluation of the deformation-stress states was used computational modelling using the finite element method. Three models of jaw geometries were created based on CT images. The implant was loaded from masticatory forces at the moment of bite. Based on the results, it can be stated that the shape and thickness of the cortical bone tissue and the density of spongiosis have a significant influence on the deformation-stress states of the bone-implant interface
