The apparatus further comprises a device for anchoring the framework to at least one anchoring tooth and pusher elements that may be spring loaded. The pusher elements are interposed between the framework and a device for fastening to a further tooth of at least one side of the arch. The pusher elements exert a distalizing force in the direction of the longitudinal axis of the arch in the region of the tooth being distalized. The pusher elements are arranged on the lingual side of the dental arch, preferably in a position lowered toward the basal gingiva and underlying bony support of the arch. Once distalizing is complete, the pusher elements can be locked to convert the apparatus into a retention device.Other References
