The Spontaneous Correction of Gingival Recession of the Mandibular Lateral Incisor through Orthodontic Torque Control: A Case Report

In this clinical case, we report the effectiveness of the orthodontic treatment in correcting severe gingival recession and bone dehiscence by repositioning the root into the alveolar bony housing of a 29-year-old female patient. Cone-beam computed tomography was used to assess the 3-dimentional root position and bone parameters before and after treatment. The root of the mandibular left lateral incisor, which was buccally positioned and the root apex was out of the alveolar bone, was moved toward the center of the alveolar bone by applying additional root lingual torque. After treatment, the root was moved into the alveolar bone and the gingival recession was corrected. This clinical case reports that orthodontic treatment, without periodontal surgery, can spontaneously correct the gingival recession and alveolar dehiscence.
