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

Stern Root Anchor is an intraradicular attachment system for retaining and stabilizing complete overdentures and removable partial dentures using retained roots of endodontically treated teeth. It features a minimal crown to root ratio by placing the point of occlusal force application within the root. The system includes connection points inside the root with an intraradicular ball and socket joint, allowing teeth with poor crown to root ratios to be used as attachment abutments for overdentures when periodontal conditions permit. The attachment comprises nylon males and titanium females with three color-coded males for three levels of retention (white, orange, grey), available in standard and mini sizes.
