This retrospective study evaluated the effect of combined periodontal-orthodontic treatment in terms of clinical, radiographic, and patient-reported outcomes in 40 stage IV periodontitis patients with advanced attachment loss and pathologic migration of anterior teeth. Full-mouth periodontal parameters were recorded at baseline (after diagnosis; T0), at the end of active periodontal therapy (APT; T1), at completion of orthodontic tooth movement (OTM; T2), and at the last supportive periodontal care (SPC) visit (T3). Radiographic analysis was performed at T0, T2, and T3. A total of 115 teeth were lost during APT, including 5 molars at T2 (used as orthodontic anchorage) and 10 premolars at T3 (due to root fracture). All anterior migrated teeth were in function at T3 (mean duration: 9.5 years). Significant mean probing pocket depth reduction (1.5 ± 1.1 mm) and attachment level gain (0.9 ± 1.0 mm) were observed after APT, whereas OTM and SPC were associated with furthering small changes. The alveolar bone level at T3 was slightly increased from T0 values. Patient-reported outcome measurements significantly improved in terms of esthetics and masticatory function. OTM should be considered an essential part of the comprehensive treatment plan to change the prognosis of severely compromised teeth in stage IV periodontitis patients.
