전치부 치성 보상기전과 장안모를 보이는 하악전돌증례에서 악교정 수술전 교정치료과정과 치료결과를 보이고자 한다. 악교정 수술전 교정치료로 장안모의 해결을 위해 구개 정중부에 mini-implant를 식립하여 상악 구치부를 압하하였고, 하악전치부 치성보상을 해결하기 위해 하악 좌우측 견치와 제1소구치 사이에 mini-implant를 식립하여 하악전치의 순측경사를 유도하였다. 그 결과 하악골 후퇴술만 시행하였음에도 수평, 수직적으로 조화로운 안모를 얻을 수 있었다. 치료기간은 11개월이 소요되었으며, 치료 후 18개월 후에도 안정적인 교합이 유지되었다.

Abstract
Treatment of skeletal Class III malocclusion with mini-implant anchorage is discussed in relation to vertical control of the maxillary posterior dentoalveolar region and horizontal control of mandibular anterior teeth. A midpalatal mini-implant provided anchorage for intruding the maxillary posterior teeth. Mandibular mini-implant implants were used to bring about labioversion of mandibular anterior teeth. After mandibular setback surgery, improvement of the facial profile was obtained both horizontally and vertically. Total treatment time was 11 months. Stable occlusion was maintained after 18 months of retention. The effectiveness and efficacy of mini-implants for the treatment of skeletal Class III malocclusion are also discussed.
