| Abstract | ||
| Background: Partially stabilized Zirconia(PSZ)coated implant demonstrated the distinct effects on the surface composition of the implant, and activates on osteoblasts. Zirconia improves cell proliferation significantly during the first days of implantation, and may improve attachment and adhesion strength of the implant. The aim of the study was to evaluate the influence of the coated biomaterial (zirconium) on osseointegration of cpTi implant radiographically with mechanical test. Materials and Methods: Seventy-two commercially pure titanium implants(cpTi)were used in this study,(24)implants were coated with PSZ by electrophoretic deposition(EPD)method,&(24) by dipping method, the rest24 implants were used as controls, they were inserted in the tibia of (32)New Zealand white rabbits & were followed for 2,&6weeks .Mechanical torque removal test for evaluation of osseointegration was performed, Results: Results revealed that bone –implant contact (BIC), increased with time &that implants coated with PSZ by dipping method have shown higher torque mean values than those coated by EPD method. Conclusion: Dip-coating of the cpTi implants with PSZ, can be considered as an alternative coating method and enhance better bone implant contact than EPD. | ||
