A stable soft and hard tissues around Osseo-integrated implants are very crucial. Soft tissue thickness around implants is crucial as it prevents peri-implant bone loss and enhance the esthetic outcomes. The treatment of thin tissue phenotype should be improved as the thin tissue phenotype will lead to plaque accumulation. There are some techniques that can increase the thickness of the peri-implant mucosa including connective tissue graft, platelet- rich fibrin and xenogeneic collagen matrix .Leukocyte and Platelet rich fibrin is a second generation platelet concentrate that was introduced by choukroun et al in 2001 after platelet rich plasma. PRF is the first source of autogenous blood derived growth factors harvested without the use of anticoagulants5. It contains various growth factors that are believed to contribute to periodontal regeneration. It promotes neovascularization and accelerated wound closing
