Comparison of clinical and radiographic status around dental implants placed in patients with and without prediabetes: 1-year follow-up outcomes

ObjectiveWe hypothesized that peri-implant soft tissue inflammation is worse and peri-implant marginal bone loss (MBL) is higher around dental implants placed in patients with prediabetes compared to healthy subjects. The aim of the present 12-month follow-up study was to compare the clinical and radiographic status around dental implants placed in patients with and without prediabetes. Material and methodsTwelve patients with medically diagnosed prediabetes (Group-1) and 12 controls (Group-2) were included. All patients were indicated for single tooth maxillary or mandibular premolar replacement with the adjacent teeth intact. Success of the restored implants was assessed by comparing clinical (peri-implant bleeding on probing [BOP], and probing pocket depth [PPD]) and radiographic (peri-implant MBL) parameters at baseline and at 12-months follow-up. Statistical analysis was performed using one-way analysis of variance, and P-values <0.05 were considered statistically significant. ResultsAt 12months of follow-up, there was no clinical evidence for the presence of plaque, BOP and peri-implant pockets with PPD4mm in both groups. At 12-month follow-up, the mean MBL among implants placed in groups 1 and 2 were 0.2 +/- 0.1mm and 0.1 +/- 0.01mm, respectively. Overall, the periodontal status (PI, BOP and PPD4mm) at 12-month follow-up was comparable among patients in both groups. ConclusionWithin the limitations of this study, it is concluded that dental implants inserted in prediabetic and healthy patients have similar success rates and remain clinically and radiographically stable after 1-year follow-up.
