The purpose of this experiment was to measure the amounts of nickel and chromium released from a simulated orthodontic appliance incubated in 0.05 percent sodium chloride solution. The average release of metals was 40 micrograms nickel and 36 micrograms chromium per day for a full-mouth appliance. This was well below the average dietary intake of nickel and chromium consumed by Americans. However, the clinician should be aware that release of nickel and chromium from orthodontic bands might sensitize patients to nickel and chromium and may cause hypersensitivity reactions in patients with a prior history of hypersensitivity of these metals.
本实验的目的是测量在0.05%氯化钠溶液中孵育的模拟正畸矫治器释放的镍和铬的量。对于全口矫治器，金属的平均释放量为每天40微克镍和36微克铬。这远低于美国人的镍和铬平均饮食摄入量。然而，临床医生应该意识到，正畸带释放的镍和铬可能会使患者对镍和铬敏感，并可能在有这些金属过敏史的患者中引起过敏反应。
