Mechanical attachments used to improve retention of overdentures have their limitations. With the recent development of the cobalt-samarium magnet an alternative method of achieving increased overdenture retention is offered. The most suitable form of magnet appears to be of a reverse split pole design with a ferromagnetic disc or keeper which will ensure a closed magnetic field. Clinical techniques involve conventional endodontic therapy, and the basic method of overdenture construction can be followed with only minor modification.
用于改善覆盖义齿固位的机械附着体有其局限性。随着钴钐磁体的最新发展，提供了一种增加覆盖义齿固位的替代方法。最合适的磁体形式似乎是带有铁磁盘或保持器的反向分裂极设计，这将确保形成封闭的磁场。临床技术涉及传统的牙髓治疗，并且覆盖义齿制作的基本方法只需稍作修改即可沿用。
