Outline of Final Research Achievements

Iodine supported implant is the novel technology with a special oxide layer and countless micro pore. It holds both antimicrobial activity and osteoinductive activity. Three kinds of examinations were performed during this research period. Relationship between the surface roughness of the metal implant and antibacterial iodine-supported process, relationship between the change of the size of the metal implant and antibacterial iodine-supported process, and relationship between the sterilization process and the antibacterial iodine-supported process. These are important results for approval of the developed product.
