Research Abstract	It is not clarified of the uniting style on implant/biological tissue interface on Nano scale still at all. Because the implant and the bone flake off in a past sample making method, the observation on implant/biological tissue interface at the electron microscope level was extremely difficult. Observing it without destroying implant/biological tissue interface at the electron microscope level as a result of this research after the observation part had been specified by the combination with the sample making method with the argon ion by the ion grinding method and Focused Ion Beam (FIB) became possible.
