In past webinars, Dr. Moe Razavi has reviewed the benefits of using the palate as the source of anchorage for en masseretraction of the maxillary anterior teeth. The Unitek™ Temporary Anchorage Device System, combined with the custom designed TransPalatal Arch (TPA), can not only be used to control the final position of the maxillary incisor teeth, but can also allow for control of almost every tooth in the mouth. In this segment, Dr. Razavi reviews treatment mechanics for anterior-posterior (AP) correction through molar distalization in both the maxillary and mandibular arches using a combined TPA/TAD system anchored in the palate.   ( disclaimer, bio and commercial disclosure )
