Retentive and stress characteristics for a magnetically retained partial overdenture.

Summary 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.
