前牙開咬的齒顎矯正治療與追蹤-病例報告

The Orthodontic Treatment and Follow up of an Anterior Open Bite Malocclusion-Case Report

摘要


由於造成前牙開咬的原因很多也很複雜,像是吸手指、吸奶嘴、舌頭外推、舌頭位置不正常、以及骨骼和牙齒等硬組識生長異常(如mandible downward and backward growth; posterior teeth over eruption)…等等。因此在進行齒顎矯正治療前,要先找出可能造成前牙開咬的可能病因、做出正確診斷,並施予有效的矯正機制,如此才能提高治療的成功率,並且能夠在治療結束後得到良好的穩定性。本文提出一個前牙開咬伴隨下門牙間隙,門牙前突的安格氏第一類不正咬合的病例,針對可能的病因,施以舌柵、全口固定矯正器拔牙治療、以及在治療過程中持續進行舌頭的myofunctional therapy等方法,藉此改善患者的咬合、功能及外觀。並且在治療完成後追蹤觀查一年,仍維持很好的穩定性。

The etiologic factors of anterior open-bite are very complexes, such as thumb sucking, pacifier suck, tongue thrust, tongue posture position, and abnormal skeletal/dental growth pattern( mandible downward and backward growth; posterior teeth over eruption)....etc. Successful identification of the etiologies will improve the chance of treatment success and the stability of retention. A 16 years-old female patient of anterior open bite with lower anterior tooth spacing was treated by tongue crib, fixed orthodontic, and myofunctional therapy to achieve improvement of patient's occlusion, function and appearance. The treatment result is still stable after follow up 1 year.
