摘要

二級異常咬合第一類的症狀如上顎前牙突出、下顎後縮、深咬及於腭側牙齦。雖然早期矯正治療來改善二級異常咬合仍有爭議，但是若能早期矯治過於突出的前牙，增加患童的自信以及避免前牙可能的意外傷害，早期的矯正治療就顯得很有意義。本病例報告介紹一位八歲九個月之國小女孩，主訴為上顎門牙暴出，要求改善「暴牙」的臉型。經一階段早期診治及二階段全口固定式矯正治療，成功地完成二級異常咬合的矯治，期間並沒有使用任何頭部牽引器或功能性矯正裝置。五年後的觀察，咬合仍然穩定。

The clinical manifestations of Class Ⅱ Division 1 malocclusion include protruded maxilla and upper incisors, retrusive mandible, and deep bite with lower incisor impinging to palatal mucosa. Controversies still exist about early orthodontic treatment for patients with Class Ⅱ Division 1malocclusion. However, early correction of the protruded anterior teeth is significant when increased child's self-esteem and decreased the risk of traumatizing anterior teeth are considered. The case report presents an 8-year-9 month girl with the complaint of severe protruded upper incisors and request for correction. Through the phase Ⅰ of early correction of anterior teeth protrusion, followed by the phase Ⅱ of comprehensive fixed orthodontic treatment, the Class Ⅱ malocclusion has been success fully treated without the use of any headgear or functional appliance. The occlusion is stable after 5-yearfollow-up.
