Purpose of test
  • The success of dental implant depends on the biocompatibility of the implant and its biofunctionality, the mechanical, physical properties for performing the relevant function.
  • As implant receives static and dynamic loads, many problems may occur in relation to biodynamics.
  • These problems may lead to destruction of abutment screw or fixture due to loosening of abutment screw.
  • Thus, research is continuously conducted on implant materials, geometric shape, general bite force, and stress analysis.
  • This test is performed according to ISO14801 regulations and predicts fatigue lifespan of implant based on S-N curve to realize implant with greater function.
