Stern Root Anchor, Transfer males for mini female, blue with white collar, 5

Stern Root Anchor retains and stabilizes complete overdentures and removable partial dentures using the retained roots of endodontically treated teeth. It features an intraradicular ball and socket joint with the connection point inside the root. The attachment places the point of occlusal force application within the root, enabling teeth with poor crown to root ratios to be used as attachment abutments for overdentures when periodontal conditions permit. This design lowers occlusal stress on the root and is suitable for cases with marginally adequate abutments.
