ABSTRACT:
A dental connector structure has a first, transmucosal cuff member which is attached to the jaw bone or tooth root through an implant fixture embedded in the bone or tooth root, and a second, keeper member to which a denture is attached. The second keeper member is removably mounted to the transmucosal cuff. A resilient, elastic member, such as an O ring, is disposed between the transmucosal cuff and the second, keeper member to permit selected limited but substantially universal motion of the keeper member relative to the transmucosal cuff, and to absorb forces transmitted by the denture through the keeper member towards the underlying bone or root structure. The resilient elastic member also keeps the transmucosal cuff and the second, keeper member from contact with one another, and thereby minimizes corrosion. The denture includes a magnetic skirt that limits the lateral movement of the denture and the keeper.
