Since 2019, orthodontic treatments of cleft lip and/or palate have been supported by the Korean National In surance System. Based on the national claim data, more than 30% of fixed orthodontic treatments were provided to adult cleft palate patients. Their maxillary arches frequently were deformed and collapsed, and sometimes needed arch coordination for alveolar bone graft. Therefore, the treatment progress for two patients with uni lateral/bilateral cleft palate was introduced, presenting improvement of inter-arch horizontal disharmony and dental alignment with fixed orthodontic appliances to enable iliac bone graft and implant prosthesis.
