Purpose: This study was conducted to evaluate the effect of glycemic control on implants assisted mandibular overdentures in type II diabetic patients after three years of function. Materials and Methods: Thirty, completely edentulous patients with a mean age of fifty years old were included in this study. For each patient two implants (3.5*13mm Anyone Two– piece dental implant, Mega Gen Implant System, Korea) were placed at the canine region bilaterally with equator attachment to retain mandibular overdenture. Patients were distributed into two groups: Group (1) contained patients who their glycemic control values below 8%. Group (2) contained patients who their glycemic control values 8% or above 8%. Each patient was evaluated clinically concerning plaque index, probing depth and implant stability by using resonance frequency analysis and radiographically concerning marginal bone loss at baseline (overdenture insertion) and after 6, 12, 24, 36 months after insertion. Data were collected, tabulated and statistically analyzed using t-Student test.
Results: There was a statistically significant difference between both groups (P < 0.05) regarding probing depth, implant stability and marginal bone loss
Conclusions: Wither the limitations of this short term study, glycemic control seems to have an effect on the survival of implants assisted complete overdentures in type II diabetic patients.
