1 patient (1M) AGE: 70 years SA: NR AOT:16/17/18	Study: L-PRF as a repair method for sinus membrane perforation (1). Control: No.	8, 14, and 20 months follow up CBCT	3,000 rpm 10 min	Graft material: DBBM Sinus membrane repairing: L-PRF + Collagen	After 6 months grafts ensured none formation form implant installation Bone graft well-delimited to the area of interest No prosthesis failure or periimplantitis The use of L-PRF associated with collagen membrane was efficient for the sealing of the sinus membrane perforation and enabled bone formation for subsequent implant installation.
