Fabrication of a Mandibular Implant-Supported Overdenture with a New Attachment System: A Review of Current Attachment Systems

Since their introduction, implant-retained overdentures have represented a feasible, economical, and highly successful treatment option for completely edentulous patients. Different attachment systems have been effectively used to retain these implant overdentures, and each system has advantages and disadvantages. Locator attachment (Zest Anchors) is one system that has been widely used by clinicians, particularly, for two-implant-supported situations. Recently, Zest Anchors developed a new locator-style abutment, Locator R-Tx. This clinical report describes the fabrication of a mandibular two-implant overdenture using this newly designed attachment system and reviews the different attachment systems currently in clinical use.
