An orthodontic device for the segmental distalization of a posterior jawbone area is disclosed. The orthodontic device comprises a mesial element having a mesial base surface for attachment to a premolar or a canine, a projection for coupling with a traction element, and an arm comprising an elongate transverse pin at a distal end of the arm, and a distal base having a distal base surface configured for attachment to a molar, and a receptacle for receiving the transverse pin. A first axis is defined as being substantially perpendicular to the distal base surface, and the transverse pin has a mesial surface and a distal surface, an interior shape of the receptacle is such that the rotation about the first axis is limited by the mesial and/or distal surface touching against an inside of the receptacle. The disclosure also relates to orthodontic kits.
