In recent years magnetic retention has gained increasing popularity in dental practice. This investigation compared the corrosion resistance of the palladium-cobalt ferromagnetic alloy (constituent of the keeper cemented on the abutment teeth) coupled with the samarium-cobalt magnets embedded in the removable part of the denture. The behavior of three couples (cobalt-palladium, cobalt-palladium/titanium, and cobalt-palladium/palladium) has been studied. The magnets, because of their poor corrosion resistance, are encapsulated in various materials. To simulate clinical conditions, characterized by the continuous movement of the keeper with respect to the magnet, the experiments were conducted in artificial saliva under intermittent and continuous wear.
近年来，磁性固位在牙科临床实践中越来越受欢迎。本研究比较了钯钴铁磁合金（粘结在基牙上的衔铁成分）与嵌入义齿可摘部分的钐钴磁体的耐腐蚀性。研究了三对组合（钴 - 钯、钴 - 钯/钛和钴 - 钯/钯）的性能。由于磁体耐腐蚀性差，它们被封装在各种材料中。为了模拟临床情况，其特点是衔铁相对于磁体持续移动，实验在人工唾液中进行，模拟间歇性和持续性磨损。
