The study carried out a periodic quantification of the amounts of metal ions accumulated in the blood of Wistar albino rat pre- and post-operative the implantation of stainless steel (SS) arch bar used for maxillomandibular fixation and compares these with the amounts accumulated in the fur used as a bio-monitor. The concentrations of the corrosion products increased from the 3 to 6 weeks post-operative periods in the blood and fur. The total metal ions accumulated in the fur and blood of Wistar albino rat in vivo follows the ranking Ni > Fe > Mn > Co > Cr. Ni shows a high affinity for the fur and blood. The concentrations of Co, Mn and Cr ions in the fur post-operative is indicative of the levels of these metal ions in the blood.
