Abstract:
Objective:To study the biocompatibility of porous Ti processed by laser solid forming(LSF)with osteoblasts.Methods:SD rat osteoblasts were seeded on porous Ti surface processed by LSF.Adhesion,proliferation and ALP activity of the osteoblasts were measured at different time,and all samples were observed under SEM.Dense sand-blasted Ti sheets were used as the controls.All data were statistically analyzed.Results:Adhered cells on porous Ti were more than those on nonporous Ti sheets after 2 and 3 hours of culture(P <0.05).At 4 and 7 days,cell proliferation and ALP activity were significantly higher on porous Ti than those on the controls(P <0.05).Conclusion:Porous Ti processed by LSF possesses good biocompatibility with osteoblasts.
