Orthodontic device or assembly of a wire material for moving in all three dimensions any desired teeth in the upper dental arch including teeth that have not erupted naturally relative to a pair of substantially transversally opposed upper teeth without the reaction forces on this pair of teeth causing unwanted movement of said pair of teeth. A palatal arch wire section adapted to fit between the mentioned pair of transversally opposed teeth and to be placed adjacent the palate comprising a multi-loop spring. The multi-loop spring corresponds to one third to one half of the palatal arch wire section width and when placed at some distance from the palate works as a bed for tongue pressure creating intrusive corrective forces on said pair of teeth. Extension spiral-formed bows with adaptation loops extend laterally from the transversal palatal arch for applying corrective forces to one or more teeth anterior or posteriorly placed in relation to the said pair of teeth. The palatal arch section receives the reactive forces of the extension spiral-formed bows and applies that force to the pair of teeth cancelling out any reactive forces transmitted to those said pair of teeth.
