METHOD FOR PRODUCING LIVING BODY IMPLANT, AND METHOD FOR REGENERATING LIVING BODY IMPLANT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a living body implant, in which the living body implant excellent in bonding force to a bone tissue of a living body is produced, and to provide a method for regenerating the living body implant.;SOLUTION: The method for producing the living body implant comprises a substrate formation step a1, a surface treatment step a2, a gamma ray irradiation step a3 in a vacuum atmosphere, a package step a4 and a sterilization treatment step a5. At the gamma ray irradiation step in the vacuum atmosphere, the living body implant is irradiated with a gamma ray in the vacuum atmosphere. As a result, foreign matter such as organic matter is not stuck to the surface of the living body implant being the final product and decomposed matter of the foreign matter is not stuck also thereto so that the deteriorated biocompatibility can be recovered and the living body implant excellent in bonding force to the bone tissue of the living body can be produced.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
