The overdenture: a concept.
Teeth that are unsuitable as abutments for a fixed bridge or removable partial denture may be retained as roots under an overdenture. While these roots remain, the vertical height of the bony ridge is preserved. In addition, the roots give support to the denture and reduce stress on the alveolar ridge.
