Adults with advanced periodontal breakdown often exhibit pathologic tooth migration, spacing, extrusion, and compromised aesthetics and function, making orthodontic correction challenging due to diminished periodontal support and heightened risk of further attachment loss. This interdisciplinary clinical strategy article proposes a structured sequencing framework to integrate periodontal regeneration with orthodontic therapy, optimizing outcomes while minimizing risks. Key elements include establishing periodontal stability before orthodontics, strategic timing of regenerative procedures (e.g., guided tissue regeneration and bone grafting), controlled low-force orthodontic mechanics, and lifelong maintenance. The framework outlines 5 phases: (1) initial periodontal stabilization through non-surgical therapy and risk factor control; (2) regenerative interventions to rebuild lost periodontal architecture; (3) orthodontic tooth movement with adapted biomechanics; (4) adjunctive periodontal re-evaluation and refinement; and (5) long-term stability monitoring with supportive care. Recent evidence demonstrates that well-sequenced interdisciplinary approaches can enhance probing depths, clinical attachment levels, bone fill, and occlusal function without aggravating periodontal destruction. This model highlights patient-specific considerations, such as defect morphology, inflammation control, and compliance, to assist clinicians in managing stage III/IV periodontitis cases suitable for tooth retention and alignment. By prioritizing periodontal health before and throughout orthodontics, the framework promotes predictable regeneration, esthetic rehabilitation, and enduring periodontal-orthodontic stability in compromised adults.
