Outline of Final Research Achievements

The antibacterial iodine-supported titanium implants has been developed in our institute and have been observed in a clinical trial. We conducted animal experiment about an osteoconductivity of the iodine-supported titanium.
A biomechanical testing of pull out strength and a histological examination of the 3 kinds of screws inserted to lumbar vertebral bodies of dogs were investigated. They were titanium screws, anodically-oxidized titanium screws, and iodine-supported titanium screws. In the both the pull out strength and histological osteoconduction, no significant differences were observed between any two of 3 types of screws. The osteoconduction of iodine-supported titanium was equivalent to that of titanium.
