Abstract

The retentive and stress characteristics of a magnetically retained partial overdenture were studied. The retentive properties were compared to those of an I-bar and Zest Anchor retained overdenture. The magnetically retained partial denture uniformly distributed stress to the supporting structures and exhibited significantly greater retention than that of the I-bar, but less than that of the Zest Anchor. Based on these observations, the magnetically retained denture should be considered as an option to be used instead of or in conjunction with other types of partial overdentures.

摘要

对磁性固位局部覆盖义齿的固位和应力特性进行了研究。将其固位性能与I型杆和Zest Anchor固位覆盖义齿的性能进行了比较。磁性固位局部义齿能将应力均匀地分布到支持结构上，其固位力明显大于I型杆固位覆盖义齿，但小于Zest Anchor固位覆盖义齿。基于这些观察结果，磁性固位义齿应被视为一种可替代其他类型局部覆盖义齿或与之联合使用的选择。
