Miniplates resist better to high discontinuous forces than miniscrews do. Therefore they can be used for intermaxillary orthopedic traction. Class III elastics can be fixed between Bollard anchors on the skeletal base of the maxilla and mandible of young growing patients. In contrast to face masks forces can be applied from bone to bone 24 hours a day. Can the growth of the maxilla and/or mandible be stimulated, restricted or redirected? Which biomechanical approach should be used? The results of a continuous pure orthopedic traction will be discussed based on a Cone-beam CT at T1 and T2 co-registrated on the anterior skeletal base.
