Abstract: Tooth ankylosis is a clinical condition where the tooth cementum directly fuses with the surrounding alveolar bone， leading to functional and aesthetic defects. The etiology involves genetic， metabolic， and local stimulation factors. The diagnosis of tooth ankylosis requires a combination of clinical manifestations and imaging examinations to improve the diagnostic accuracy. The treatment of tooth ankylosis presents significant challenges. Orthodontic treatment combined with other disciplines offers a new， comprehensive treatment approach， integrating traditional orthodontic techniques with osteotomy， distraction osteogenesis， orthodontic bone traction， corticotomy， dislocation， and autologous tooth transplantation techniques. The treatment of tooth ankylosis requires the cooperation of multiple disciplines， and the experts from orthodontics， oral surgery， and oral medicine collaborate to develop the optimal treatment plan. This comprehensive treatment method achieves better outcomes compared with traditional treatments. This review discusses the etiology， diagnosis， and orthodontic combined multidisciplinary treatment methods of tooth ankylosis， analyzes the advantages and disadvantages of various treatment options， evaluates the efficacy and risks， and provides new perspectives for the treatment of tooth ankylosis.
