A force module is interconnected between upper and lower dental arches of an orthodontic patient in order to move the positions of the arches relative to each other. The force module includes at least two sliding members that move relative to each other along with a link for connecting one of the sliding members to one of the dental arches. The link is pivotally movable about two spaced apart, parallel reference axes that are generally perpendicular to the axis of sliding movement of the members. The link enables the force module to be readily shifted in a lingual direction as the patients jaws are closed.
