- OBJECTIVES: A novel technique based on plasma immersion ion implantation (PIII) is presented to modify titanium implant surfaces. MATERIALS AND METHODS: Initially, the implants are cleaned with argon to remove contaminants and the nanostructures are created by the bombardment of the surface with a mix of noble gases. Desired crystal structure of the titanium is obtained by the implantation of oxygen on the contaminant-free surface with particular nanostructures. RESULTS: In this study, turned implants modified by PIII revealed a high density of rutile-TiO(2) nanostructures. Turned implants used as control revealed mainly microstructures and amorphous crystal structure. Surface roughness values were similar at the microscale for both turned and turned+PIII implants. Bone response was evaluated by removal torque tests of implants placed in the rabbit tibia and femur. After 4weeks of healing, turned+PIII demonstrated higher removal torque values (P=0.001) compared to turned implants. CONCLUSIONS: The presence of rutile-TiO(2) nanostructures may explain the improved bone formation to turned+PIII implants.
