Stern Root Anchor, Caps, 5

The Stern Root Anchor retains and stabilizes complete overdentures and removable partial dentures using the retained roots of endodontically treated teeth. The attachment places the point of occlusal force application within the root, creating an intraradicular ball and socket joint. This design allows teeth with poor crown to root ratios to be used as attachment abutments for an overdenture when periodontal conditions permit. Intraradicular connection of attachment components lowers occlusal stress on the root. The system includes standard and mini size options with three color-coded males for three levels of retention (lightest to strongest: white, orange, grey). The female component is cemented directly in root preparation, while the male is polymerized into denture acrylic. The universal hinge design accommodates highly divergent abutments.
