title: Bodily tooth movement through the maxillary sinus with implant anchorage for single tooth replacement.
abstract: Movement of teeth through anatomic limitations, such as the maxillary sinus, can be a reliable therapeutic protocol if suitable force systems are used. We report here the outcome of a treatment based on this concept. The patient exhibited pneumatization of the maxillary sinus resulting from earlier extractions. She was treated using an endosseous implant inserted in the retromolar region to serve as orthodontic anchorage and a T-loop appliance fabricated from TMA wire to bodily move an upper second premolar through the sinus. After 6 months, at the end of the displacement, a titanium implant was inserted in the alveolus of the moved tooth and a single crown restoration was placed. The premolar moved through the sinus maintaining its support apparatus and bone. At the end of treatment the implant used for anchorage was still osseointegrated.
