Abstract Purpose: The aim of this study was to compare clinically between single and two implants retaining mandibular complete overdentures as regards bleeding on probing and the depth of peri-implant sulcus. Subjects and Methods: Twelve completely edentulous males were enrolled in the study and were randomly divided into two equal groups. First group received two implants at the canine areas. Second group received a single implant at the midline. The degree of peri-implant inflammation was assessed using the modified Bleeding on Probing Index and by measuring the depth of the peri-implant sulcus (probing depth). Assessments were carried out two weeks after overdenture delivery, then one, two and three months later to evaluate the soft tissue changes around the implants. Mann Whitney test was used for between-group comparison, and Friedman test was used for within group comparison. The significance level was set at P ≤. 0.05. Results: There was a gradual decrease in bleeding on probing and probing depth within each group. However, this decrease was not statistically significant. Similarly, for both parameters, there was no statistically significant difference between both groups at all follow-up periods. Conclusion: One implant retained overdentures showed comparable results to two implant retained overdentures as regards bleeding on probing and probing depth. Keywords: single implant retained overdentures, two implant retained overdentures, bleeding on. |
