Surface morphology of the polished Ti and Ti with different surface modification. Control: polished Ti; SLA: 400 μm SiO2 sandblast + acid etching; SLA + HT4h: 400 μm SiO2 sandblast + acid etching + 4 mol/L NaOH hydrothermal for 4 h; SLA + HT8h: 400 μm SiO2 sandblast + acid etching + 4 mol/L NaOH hydrothermal for 8 h. 1 represents 1000x magnification; 2 represents 5000x magnification; 3 represents 50000x magnification.
