| Outline of Final Research Achievements |
Recently, Advanced Glycation End products (AGEs) known to accumulate in bone collagen by diabetes mellitus was reported to have a relationship with reduction of bone quality. However, it was not clarified the correlation between accumulation of AGEs and implant treatment success due to established osseointegration. The aim of this study was to investigate the effect of accumulation of AGEs during osseointegration using diabetes mellitus model rats. There were no significant deafferents between new bone formation in the bone defect area and around implant body of experimental group and those of control groups. On the other hands, positive immunoreaction of AGEs was recognized at the implant neck area of cortical bone in experimental group. From those result, accumulation of AGEs does not have relationship with early stage of osteointegration. However, AGEs is suggest to effect the long-term success rate, because implant neck area was known to be starting point of peri-implantitis.
