Osseointegration features of orthopedic Ti–10Si–5B implants

The present work reports on osseointegration features in rabbit tibia of orthopedic Ti–10Si–5B implants, which present a typical structure formed by the Ti and Ti6Si2B phases. No inflammatory reaction or rejection was noted after implantation for sixteen weeks of smooth and rough Ti–10Si–5B screw implants. Results indicated that the removal force for Ti–10Si–5B screws was continuously increased after implantation for sixteen weeks, suggesting that the bone integration process was achieved. Histological analysis revealed the occurrence of normal bone tissue growth and the presence of osteoblasts near the metal–tissue interface. Higher torque values were used to remove the rough Ti–10Si–5B screw implants after sixteen weeks, denoting that the surface treatment provided superior anchor for bone tissues. The absence of inflammatory reaction during implantation of orthopedic Ti–10Si–5B implants for sixteen weeks denotes the good bone compatibility of the composition alloy.
