Evaluation of Peri-Implant Tissues of Different Implant Assisted Overdentures

Summary

The researchers will perform a parallel randomized, clinical trial involving completely edentulous healthy patients. Each participant will receive four dental implants in the anterior mandible. According to the processing technique and denture base material, the patients will be classified into three groups. Group I: involves CAD/CAM milled poly ether ether ketone PEEK overdentures, Group II: involves CAD/CAM milled PMMA overdentures and Group III :involves conventional heat-cured poly methyl methacrylate PMMA overdentures. All assessments were carried out at delivery, 6 moths and one year after overdenture insertion to clinically evaluate the preiimplant tissues. .

Interventions

PROCEDURE

the plaque index (PI)

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).

PROCEDURE

the bleeding index (BI)

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. 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).

PROCEDURE

simplified gingival index(GI),

Peri-implant soft tissue changes as regards gingival scores was assessed simplified gingival index(GI). 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
