Stern Root Anchor®, Oversized males for std. female, orange w/ black collar

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 an intraradicular ball and socket joint connection point inside the root. Teeth with poor crown to root ratios can be used as attachment abutments for an overdenture when periodontal conditions permit. The approximate diameter of the ball area is 1.8mm for orange males.
