BACKGROUND: The reactive correction of a single tooth anterior crossbite following periodontal therapy is described. This case report provides new information regarding correction of a crossbite relationship and con- firms existing reports of tooth movement following periodontal therapy. METHODS: A 39-year-old woman in good general health presented with a history of recurrent periodontal abscesses of a maxillary incisor. Probing depths of the abscessed tooth ranged from 5 to 12 mm, and class 1 mobility was noted. Radiographs revealed that the tooth had previously been treated endodontically. The patient's periodontal diagnosis was generalized chronic moderate to severe periodontitis. Treatment considerations were complicated by a single-tooth crossbite relationship of the involved incisor and clinical evidence that the periodontal abscess communicated with an apical infection. Treatment of the abscess consisted of cause-related therapy, bone grafting, and occlusal adjustment. RESULTS: Five months after surgical treatment, an edge-to-edge incisal relationship was observed, the first indicator of tooth movement. Further correction to a normal incisal relationship resulted 1 year after modification of the proximal contact. At this time, there was normal probing depth with only slight recession and mobility. Bone fill was radiographically noted. CONCLUSION: It appears that some cases of maxillary incisor crossbite that are complicated by periodontal disease may be corrected, without orthodontic appliances, following periodontal treatment.
