摘要：

The aim of this study was to assess the metal elements in two commonly used orthodontic polymeric aligner and retainer, and evaluate the in vivo accumulation in blood by animal experimentation. Elements of Al, Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Sn were quantified in appliances before-use and after two weeks' wearing. Intraoral usages were modeled in Wistar rats and vein blood was extracted at Day 28, Day 56 and Day 112. Trace elements analyses were conducted by inductively coupled plasma mass spectrometry (ICP-MS). Al, Ti, V, Cr, Fe, Co, Ni, Cu, Zn were detected in retainers, and Al, Ni, Zn and Sn were found in aligners. The identified element levels were significantly decreased after two weeks' intraorally wearing. The contents of metal in polymeric materials neither exceed the toxic levels nor the daily dietary intake. No in vivo accumulation effects were found in blood.
