The present study showed that the combined orthodontic and periodontic therapy performed resulted in the realignment of extruded teeth with infrabony defects, obtaining a significant probing depth reduction, clinical attachment gain, and radiological bone fill.

The presented clinical protocol resulted in improvement of all parameters examined. At the end of orthodontic treatment a predictable reduction of REC was reported, both in patients with thin or wide gingiva.

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.

The proposed clinical protocol may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level, together with resolution of the periodontal defects.
