Objective: This study compared and evaluated the clinical and radiographic results of guided bone regeneration using platelet-rich fibrin (PRF) and collagen membrane as barrier membrane in immediately placed implants with severe buccal bone defect (with respect to marginal bone level, implant stability quotient [ISQ]), and histological analysis of new bone formation. Materials and Methods: Sixteen implants were placed in patients requiring immediate implant placement and having a buccal wall defect and randomly divided into two groups one receiving PRF membranes and other collagen membrane. The sites were grafted with bone-substitute material in both the groups. After 4 months, at the time of second-stage surgery, implant stability is measured by Osstell Mentor, crestal bone level on mesial and distal sides of implant by digital intraoral periapical, buccal defect clinically by probe and histological analysis of biopsied bone. Results: The results were insignificant and comparable in both the groups when comparison was made between the groups. The mean buccal defect, mean values of average ISQ, crestal bone level in both the groups at baseline and after 4 months were compared. No significant difference between both the groups was found after 4 months. Bone quality seemed to be equal in both groups after histological analysis. Within the limits of the study, both the groups had shown similar results in all criteria. Conclusion: Within the limitation of the study, it can be concluded that both the treatment modalities are successful in terms of buccal defect reduction, stability, and increase in crestal bone level.
