Outcome and follow-up
All tooth movement, gingival hemorrhage, and gingival swelling resolved or improved, with no abnormalities in occlusion(Fig 2B). Periodontal pockets were less than 3 mm in all jaws (Table 1B). Bone growth was observed on panoramic radiographic findings in the area of significant alveolar bone resorption, and the alveolar hard line, mandibular canal wall, and bone beam structure, which had been unclear, became clear. On day116 after the start of treatment, in the mandibular left molar, which had been significantly resorbed, the jawbone, which had been seen up to about one-third of the root apex at the initial examination, had grown up to the tooth cervix (Fig 3B).
