Association between diabetes and dental implant complications: a systematic review and meta-analysis.

A final total of 10 published studies were included in this systematic review. There were statistically significant differences between the groups with regard to marginal bone loss (p < .00001), probing depth (p < .00001) and bleeding around dental implants (p < .00001), and subjects without diabetes had lower complication rates. Additionally, in the subgroup analysis performed with loading time and HbA1c levels, a more evident association was found in immediate loading for probing depth. Moreover, the analysis results of bleeding around dental implants suggested that as HbA1c level increases, the bleeding of the tissues surrounding the implant will also increase. With regard to dental implant complications, there were statistically significant differences favouring patients without diabetes mellitus.
