Clinicians often encounter osseous defects that are best treated by conventional surgical techniques, including bone grafting and guided tissue regeneration, with a goal of establishing a new connective tissue attachment. On occasion, the recognition of an infrabony defect proximal to a tooth with a large diastema may present an opportunity to consider resolution by orthodontic tooth movement. Ideally, the tooth could be moved in the proximal direction until there was no further radiographic or clinical evidence of the predisposing defect. The authors decided to treat an advanced case of adult periodontitis, with extrusion and migration of a maxillary central incisor, using a multidisciplinary approach. Radiologically, a large infrabony defect was present on the mesial aspect of the incisor, with an initial probing depth of 9 mm. After the surgical periodontal therapy, the orthodontic movement started and the incisor was repositioned using an intrusive mechanism, also leading to the closure of the diastema. At the end of the treatment, there was a significant clinical decrease in the probing depth values, and radiographs showed a remarkable reduction of the infrabony defect volume.
