| Research Abstract |
This study aimed to examine the influence of various loading on dynamic changes of bone-metabolism around the implant using a super-high resolution [18F]NaF-PET in rat tibiae. Adult male Wistar rats installed experimental implant on the tibia were used in this study. Increase of bone-metabolism was observed until 7 days after implantation surgery and then gradually decreased. Differences in bone-metabolism between immediate loading and no-loading group were found. This suggests loading affects bone-metabolism around the implant. Also
