Objective: The aim of this study was to investigate the stress distributions in a surface-treated dental implant and bone under physiological load. Methods: The nanoporous surface-modification films were characterized by scanning electron microscopy to analyze surface morphology. The novel implant surface used in this study was complex and difficult to represent because of limitations in computer performance. However, this complex geometry could be simplified using a nanoporous film to investigate stresses resulting from treatment of surfaces with 0-10-μm thicknesses. Results: The study results indicated that the stresses were more uniform in implants coated with nanoporous films that underwent surface treatments, and the stresses were reduced with increasing film thickness. Conclusion: These nanoporous surface modifications can be potentially beneficial in reducing the stress in dental implants.
