The effects on Vitallium and Ticonium alloys immersed in different concentrations of sodium hypochlorite for various immersion times are described. The results of this investigation demonstrate that samples of these metals soaked in 2% sodium hypochlorite for at least 5 minutes or in 5.25% sodium hypochlorite for a minimum of 3 minutes were sterilized and not tarnished or corroded. Although Vitallium alloy was more resistant than Ticonium alloy to the deleterious effects of sodium hypochlorite, either metal can be safely immersed for sterilization purposes under the guidelines presented. Therefore, an effective and economical method for sterilizing removable partial denture frameworks made of chrome-cobalt or chrome-nickel alloys is attainable through the proper use of household bleach.
描述了在不同浓度的次氯酸钠中浸泡不同时间对维他灵合金和钛钴镍合金的影响。本研究结果表明，将这些金属样品浸泡在2%的次氯酸钠中至少5分钟或浸泡在5.25%的次氯酸钠中至少3分钟可实现灭菌，且不会出现变色或腐蚀。尽管维他灵合金比钛钴镍合金更能抵抗次氯酸钠的有害影响，但根据所提供的指导原则，两种金属均可安全浸泡以达到灭菌目的。因此，通过正确使用家用漂白剂，可获得一种有效且经济的方法来对由铬钴合金或铬镍合金制成的可摘局部义齿支架进行灭菌。
