A Case of Mandibular Prognathism with Generalized Aggressive Periodontitis and Crowding

Aggressive periodontitis during adolescence has a poor prognosis due to rapid alveolar bone resorption. Few studies have investigated long-term follow-up after surgical orthodontic treatment performed in conjunction with that for invasive periodontitis. Here, we report case of mandibular prognathism accompanied by generalized aggressive and crowding. A 31-year-old woman was referred our department masticatory dysfunction reverse overjet. The patient exhibited class III molar relationship, protrusion the ANB －6.0°, severe maxillary Initial periodontal examination revealed deep pockets extensive inflammation. Mandibular crowding diagnosed. Therefore, it necessary adopt an interdisciplinary approach involving surgical, orthodontic, treatment. Prior commencement treatment, plaque control, scaling, root planing all teeth were periodontist suppress inflammation reduce probing depth. During pre-surgical first premolars extracted incisors. To correct prognathism, mandible repositioned sagittal split ramus osteotomy. Proper occlusion incisors maximum intercuspation achieved post-surgical After completion active acceleration observed together aggravated resorption surrounding molars. However, reduction depth scaling planing. surgical-orthodontic time 1 year 11 months, which followed 2-year retention period. There no tooth loss periodontitis, overall satisfactory outcome achieved.
