A motion restoring intervertebral device includes first and second articulating components positioned between adjacent vertebrae with the articulating surface of the first component being formed by a circular domed convex projection having a first radius. The articulating surface of the second component is formed by a generally concave recess having the first radius in the medial-lateral direction and a second larger sweeping radius in the interior-posterior direction so that the components are capable of rotating against each other in all directions and translate against each other in the anterior-posterior direction, whereby translation away from the center of the first radius will produce device and joint distraction to limit excessive translation.
