Effects of implant angulations and attachment configurations on the retentive forces of locator attachment-retained overdentures. Uludag B, Polat S, Sahin V, Çomut AA. PURPOSE: The aim of this study was to evaluate the effects of different implant angulations and attachment configurations on the retentive forces of locator attachment-retained. Many types of attachments can be used with implant overdentures such as magnets, Ball/O-Ring, bar (s)/clip (s), and locator attachments. To guarantee sufficient stability, finest shape, form, appearance, and comfort, the overdentures should be cautiously planned Locator overdenture. A big misconception is that the denture is solely retained by the bar/attachments. This is not so. All overdentures must have support from both tissue and attachments. The denture rests on the soft tissue. The attachments act only as a lock, preventing the denture from dislodging In comparison, done between overdentures retained by ball and socket attachment and another design retained by two clips on a bar connecting the two implants, regarding stresses on the peri-implant bone. The result revealed that stress on the peri-implant bone was greater with the clip/bar than that of ball attachment. After 3-year of the. Simplifying Implant-Retained Overdentures.
