Stern Root Anchor, Friction grip (FG) diamond bur for standard female

The Stern Root Anchor retains and stabilizes complete overdentures and removable partial dentures using the retained roots of endodontically treated teeth. It has a minimal crown to root ratio because the attachment places the point of occlusal force application within the root. Features intraradicular ball and socket joint with nylon male and titanium female components. Includes three color-coded males for three levels of retention (white, orange, grey). Diamond bur used for site preparation with built-in stop to prevent over-drilling.
