Aim: Biomimetic implant surface coatings can improve osteoblast response and enhance osseointegration. This study aimed to assess the response of osteoblast-like cell line (MG-63) coating of injectable platelet-rich fibrin on titanium discs.
Materials and methods: Injectable-PRF (i-PRF) was prepared by centrifugation of blood at 700 rpm for 3 minutes without any anti-coagulant in i-PRF tubes. Ten commercially pure titanium discs were divided into control groups comprising plain discs, and test group, titanium discs were coated with i-PRF. These were then added to the cultured MG-63 cells. Cell proliferation, alkaline phosphatase production, and mineralization were assessed in both groups at day 1, 7, 14, and 21.
Results: The cell proliferation, alkaline phosphatase production, and mineralization increased significantly from day 1 to day 21 in both test and control groups and was significantly higher in the test group than in control group at day 1, 7, 14, and 21 (p <0.001).
Conclusions: Coating of titanium discs with i-PRF causes increased proliferation, alkaline phosphatase production, and increased mineralization at day 1, 7, 14, and 21 in MG-63 osteoblast-like cells.
Clinical significance: Improved osteoblast proliferation and mineralization demonstrate enhanced activity on the surface of an implant, which in turn may lead to increased bone to implant contact and faster/ and/or enhanced osseointegration.
