Early Treatment of High Angle Class Ⅱ Division 1 Malocclusion: A Case Report

顏面高角度二級異常咬合第一類之早期矯正治療-病例報告

摘要


二級異常咬合第一類的症狀如:上顎前牙突出、上顎內縮、下顎後縮伴隨延長的下顎前齒、深咬及於腭側牙齦。雖然早期使用功能性矯正裝置與頭套來促進下顎生長或抑制上顎生長,以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七歲六個月之國小女孩,其咬合被診斷為顏面高角度二級異常咬合第一類,經過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。四年後的觀察,咬合仍然穩定。

並列摘要


The clinical manifestations of Class Ⅱ Division 1 malocclusion include procumbent maxillary anterior teeth, constricted maxillary arch, retrusive mandible with elongated mandibular anterior teeth, and large overbite and overjet. Controversies still exist whether an enhanced mandibular growth or an inhibited maxillary growth can be achieved through the early use of functional appliances or headgears. 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 a 7-year and 6-month-old girl diagnosed with a Class Ⅱ Division I malocclusion. Through the phase I of early correction of maxillary anterior teeth, followed by the phase Ⅱ of comprehensive fixed orthodontic treatment, the Class Ⅱ malocclusion has been successfully corrected without the use of any headgears or functional appliances. The occlusion is stable after 4 years of follow-up.
