This study investigates the release of metal ions from commonly used orthodontic archwires, specifically, stainless steel (SS), nickel-titanium (NiTi), chromium-cobalt (CrCo), and titanium-molybdenum (TMA) alloys. To simulate oral conditions, each type of wire was immersed in artificial saliva at body temperature for a four-week period. Ion release levels were analyzed through ICP-OES mass spectrometry. The findings indicate that NiTi and CrCo wires released significantly higher amounts of nickel (Ni) and chromium (Cr) ions compared to SS wires. These findings underscore the potential risk of allergic reactions, particularly to nickel, and emphasize the need for careful consideration of biocompatibility in orthodontic material selection. This research also provides valuable insights aimed at minimizing adverse reactions in patients, especially those with metal allergies.
本研究调查了常用正畸弓丝中金属离子的释放情况，具体包括不锈钢（SS）、镍钛（NiTi）、铬钴（CrCo）和钛钼（TMA）合金。为模拟口腔环境，将每种弓丝在体温下浸入人工唾液中四周。通过电感耦合等离子体发射光谱质谱法（ICP-OES）分析离子释放水平。研究结果表明，与不锈钢弓丝相比，镍钛和铬钴弓丝释放的镍（Ni）和铬（Cr）离子量显著更高。这些发现强调了过敏反应的潜在风险，尤其是对镍的过敏反应，并强调在正畸材料选择中仔细考虑生物相容性的必要性。本研究还提供了宝贵的见解，旨在尽量减少患者的不良反应，尤其是对金属过敏的患者。
