Orthodontic treatment in patients with periodontally compromised dentition often presents challenges, necessitating special considerations. This case report describes treatment of a 52-year-old female patient with advanced chronic periodontitis and pathologic tooth migration through an interdisciplinary orthodontic–periodontal approach. By integrating comprehensive periodontal treatment with strategic use of miniscrew-assisted rapid palatal expansion (MARPE) and careful consideration of the applied force systems, both functional and esthetic concerns were addressed without causing adverse periodontal side effects. This highlights the importance of thoughtful treatment planning and integration of periodontal care during orthodontic tooth movement in treating individuals with reduced periodontal health for successful and esthetically pleasing results.
