Evaluation of Peri-Implant Tissues of Different Implant Assisted Overdentures

Peri-implant soft tissue changes as regards plaque was assessed employing the modified plaque index (PI). Patients were evaluated clinically at the time of mandibular overdenture insertion (T0), 6 months (T1), 12 months (T2) and 3 years (T3) after denture insertion. Both plaque index (PI) and bleeding index (BI) were evaluated according to the Mombelli index , and gingival index (GI) according to the modified Silness and Loe index. Measurements were taken from the buccal, lingual, mesial, and distal aspects of each implant. All the clinical parameters were measured from the four aspects using a graduated periodontal probe (Hawe Perio-Probe, Kerr), and the sum total of the four readings was divided by four to obtain the mean value. The distance between the marginal border of the peri-implant mucosa and the tip of the probe was measured and considered as pocket depth (PD).

Peri-implant tissue changes as bleeding score was assessed employing the bleeding index (BI) . Patients were evaluated clinically at the time of mandibular overdenture insertion (T0), 6 months (T1), 12 months (T2) and 3 years (T3) after denture insertion. Both plaque index (PI) and bleeding index (BI) were evaluated according to the Mombelli index , and gingival index (GI) according to the modified Silness and Loe index.
