For orthodontists, it is important to maintain the stability of occlusion and soft tissue after orthodontic treatment. This article presents a patient orthodontic retreated with glossectomy 13 years after orthognathic surgery. The patient was a 33-year-old female. She had undergone orthognathic surgery at 19 years old.Although glossectomy had been recommended because of macroglossia tendency at that time, it was not per-formed. Thirteen years after orthognathic surgery, unstable occlusion and exposure of lower incisor tooth roots developed. The countermeasure against this condition, orthodontic treatment with glossectomy and gingival transplant, was taken, as she was willing to accept any necessary treatment. As the re-treatment result was good, we report it.
