Attachment ratios (A), OD values (B) and ALP activities (C) of MC3T3-E1 cells on PEEK, 80FPK and 160FPK at different times after culturing (*p < 0.05, vs. PEEK).
Abbreviations: OD, optical density; ALP, alkaline phosphatase; PEEK, polyetheretherketone; 80FPK, femtosecond laser treated polyetheretherketone with processing power of 80 mW; 160FPK, femtosecond laser treated polyetheretherketone with processing power of 160 mW.
