Titanium-Prepared Platelet-Rich Fibrin Versus Connective Tissue Graft on Peri-Implant Soft Tissue Thickening and Keratinized Mucosa Width: A Randomized, Controlled Trial

Purpose The health of peri-implant tissues is associated with the peri-implant soft tissue thickness (STT) and keratinized tissue width (KTW). Resorptive changes in the crestal bone around implant sites will be affected by the STT. The present randomized prospective study compared the effectiveness of titanium-prepared platelet-rich fibrin (T-PRF) with that of connective tissue graft (CTG) on peri-implant STT, KMW, and crestal bone level....
