Integrating Periodontal Care and Orthodontic Treatment: A Case Study of a Patient Treated With Clear Aligner Therapy (CAT).

Adult orthodontic treatment in patients with periodontal fragility requires careful interdisciplinary planning. This case report describes the interdisciplinary management of a 52-year-old female patient presenting with generalized gingival recessions (GRs), thin periodontal biotype, and dental crowding, treated using clear aligner therapy (CAT) combined with periodontal follow-up and postorthodontic mucogingival surgery. Orthodontic treatment was carefully planned to reposition dental roots within the alveolar housing while minimizing periodontal risk in the absence of CBCT. Following orthodontic alignment and retention, connective tissue grafting was performed to treat residual GRs. Clinical, radiographic, and occlusal outcomes demonstrated stable periodontal conditions, changes in occlusal contact distribution, and satisfactory esthetic results at 1-year follow-up. The uniqueness of this case lies in the use of clear aligners as a periodontal-supportive orthodontic strategy, combined with delayed surgical intervention, highlighting the role of precise root control and interdisciplinary coordination in periodontally fragile adult patients.
