Abstract

Objectives: To evaluate and compare clinical and radiographic parameters viz. Gingival Index (GI), Plaque Index (PI), Width of Keratinized Tissue (WKT), Midbuccal & Midlingual/Midpalatal soft tissue thickness (STT), ISQ values and crestal bone levels (CBL) using CBCT at baseline and 6 months in Group I (Immediate implant placement & A-PRF+) and Group II (Immediate implant placement & Collagen Membrane).

Methods: A total of 20 sites indicated for extraction were selected and randomly divided into: GROUP I : 10 sites were treated with immediate implant placement and covered with an A-PRF+ membrane and GROUP II : 10 sites were treated with immediate implant placement and covered with collagen membrane.

Results: Both groups showed significant reductions in plaque and gingival scores from baseline to 6 months (p D 0.001), indicating improved oral hygiene and gingival health. Implant stability (ISQ) increased significantly in both groups, with

a greater mean change in Group II (p D 0.001). The width of keratinized tissue and soft tissue thickness (mid-buccal and mid-lingual) increased significantly in both groups, with a greater change in Group I (p D 0.001). Buccal and lingual crestal bone levels decreased significantly in both groups (p D 0.001), though intergroup comparisons were non-significant. Overall, both A-PRF+ and collagen membrane effectively enhanced implant stability and soft tissue parameters.

Conclusion: Three months following tooth extraction, a physiological thickening of the facial soft tissue occurs concurrently with significant bone loss beneath it. The present study highlights the effectiveness of both A-PRF+ and collagen membrane in enhancing overall clinical outcomes following immediate implant placement.
