Abstract

According to the failure of Ti dental implant due to the interface mismatching in clinic,polyurethane(PU)polymer coating was prepared by pulling Ti from PU solution in order to mimic the function and properties of human periodontal tissue.Then,PU-coated Ti was biomineralized by being immersed into supersaturated Ca-P solution for different periods.The physico-chemical properties of the biomineralized PU were characterized and analyzed by means of SEM,EDX,IR,XRD,DSC-TG and water contact angle testing,and the behaviors of MG63 cells were studied by co-culture test.The results indicate that the deposit on PU is formed by the agglomeration of microspheres made of nano-flake crystals and its main ingredient is proved to be poorly crystallized and non-stoichiometric hydro apatite crystals.Also,the biomineralized PU coating has better biocompatibility than PU coating and is more favor of the proliferation and growth of MG63 cells.
