Bone destruction resulting from chronic periodontal disease disturbs the equilibrium of these interactive balances, leading to pathologic tooth migration, often requiring multidisciplinary treatment approaches. The present case demonstrates a systematic periodontalorthodontic- prosthetic treatment for achieving the optimal structural, functional, and esthetic outcomes.
