Abstract:
Objective: To study the effect of zinc supplement on bone-contacting implant surface ratio (BCSR).Methods: 40 rabbits with titanium implants placed into the proximal tibial heads were divided randomly into zinc supplement group(n=20) and control group(n=20). 1% zinc sulfate in 0.9% saline was administered intramuscularly at the dose of 4 mg/(kg?d) for each tested animal, and the same amount of 0.9% saline was used for the controls. The animals were sacrificed 1, 2, 4, 8 and 12 weeks after treatment respectively.BCSR,bone zinc content and serum Cu/Zn values were measured with morphometry, atomic absorption photometry and atomic nebulizntion absorption method respectively.Results: Zinc supplement could significantly increase the BCSR value (P0.05). Conclusion: Moderate zinc supplement may increase the bone-contacting implant surface ratio, but not alter the zinc metabolism.
