Effectiveness of Invisalign？？ aligners in the treatment of severe gingival recession: A case report

In this report, we demonstrate the effectiveness of the Invisalign？？ system in the treatment of severe gingival recession and bone dehiscence through torque, translation, and intrusion movements in a young woman. Cone-beam computed tomography was used to assess bone parameters and check the teeth during treatment. The root of the mandibular right central incisor, which was buccally positioned and exhibited bone dehiscence of 9.4 mm, was moved toward the center of the alveolar process by using the Invisalign？？ system and SmartForce？？ features. The patient was monitored by a periodontist throughout the orthodontic treatment period. Her gingival recession reduced, while the bone dehiscence reduced from 9.40 mm to 3.14 mm. Thus, movement of the root into the alveolus promoted bone neoformation and treated the gingival recession. The findings from this case suggest that orthodontic treatment using the Invisalign？？system, along with periodontal monitoring, can aid in the treatment of gingival recession and alveolar defects.[Korean J Orthod 2021;51(4):293-300]
