Abstract: A novel auxiliary element for orthodontic plates will permit sagittal tooth movements in the region of the side teeth, especially distal movements. The auxiliary element consists of a base of plastic and of a spring element embedded in this base plate and made of an elastic, but permanently deformable material. Depending on the number of teeth to be moved, one or more such spring elements are cast into the base plate and are then activated accordingly, that is to say bent in the appropriate direction. The spring element comprises two clamping arms, one of which is made U-shaped and engages over the adjacent tooth, while the other clamping arm comprises a loop part, one leg of which engages on the tooth to be moved.
