The Effect of Injectable Platelet-Rich Fibrin in Peri-implant Soft Tissue

The injectable platelet rich fibrin will be integrated into the tissue by subgingival and submucosal application to the keratinized gingiva of the implant sites with insufficient peri-implant soft tissue phenotype. Then, the prepared injectable platelet rich fibrin will be injected into the mucogingival junction apical to the keratinized gingival site. This procedure will be repeated 3 times in total, 1 time in 30 days for 3 months.
