Local application of ibandronate enhances early fixation of implants X-ray, histomorphology and biomechanical pull-out tests / 中国组织工程研究

ABSTRACT

BACKGROUND: The aseptic loosening of prosthesis has become one of the most obvious matters after operation of prosthesis replacement. OBJECTIVE: To verify the effect of ibandronate on early fixation of implants by local application. METHODS: Forty-four Zelanian rabbits were used in the experiment. A standard animal model of the rabbits' both tibia was embedded with metal screw into the proximal end. Ibandronate at 1 mg/L was sprinkled locally in the left tibia of every rabbit (experimental group), while saline solution was given in the right tibia (control group). (P < 0.001). These findings indicate that, local application of ibandronate solution can obviously promote new bone formation at the earlier period, improve early fixation of implants and decrease the incidence of aseptic loosening of prosthesis.
