Abstract: The aim of this paper was to evaluate the effect of grid size on the fatigue
life calculations of a dental implant by conducting a non-linear contact FEM
analysis. A Nobel - Biocare (Replace - Select) implant was chosen and
modelled in CATIA after retrieving accurate dimensions from SEM. The
mandibular bone was modelled using MIMICS software. Static and dynamic
simulation was then conducted on the final assembly using ANSYS which is a
commercially available FEA software package. It was observed that variation
in grid size leads to significant variation in the life of the dental
implant. Hence for an accurate estimation of fatigue life of the dental
implant the mean of the range of values must be considered.
Keywords: Finite element analysis, fatigue, dental implants
