Abstract


Success of immediately loaded dental implant can be achieved by selecting appropriate implant dimensions through establishing their correlation with interfacial strains which are responsible for bone healing and osseointegration process. This study aim was to correlate maximal bone strains induced by variable-sized implants with functional loads for the purpose of their comparing with mean experimental functional load. 3D models of 24 implant-bone assemblies were designed and finite element analysis was performed in ANSYS 15. Maximal first principal strains were analyzed. Current ultimate functional load values, corresponding to 3000 μstrain of pathological bone turnover, were determined and compared with 120.92 N mean experimental functional load to evaluate the success prognosis. Strains were found directly dependent on bone quality and implant dimensions. So, bone strains alone have an impact on immediate loading success. It is favorable for tested implants placed in type III bone, if functional load does not exceed 120.92 N. Type IV bone is completely unacceptable for immediate loading
