中文摘要 | 前牙開咬為多種因素相互影響造成,包括先天顎骨垂直方向發育比例不佳、或遺傳性疾病,及後天環境,如牙齒萌發與齒槽骨生長的變異、神經肌肉組識生長的不協調、不良的口腔習慣等因素,增加矯正治療的難度及復發的機率。治療時依其成因、嚴重程度及介入時機,有許多方式,從改善不良習慣、牙齒移動、到複雜的正顎手術,都要經過審慎的評估與計劃。本報告提出一個安格氏二級異常咬合且前牙開咬的14歲女孩,藉拔除上、下顎四顆第一小臼齒,使用傳統固定矯正裝置,配合短期二級橡皮筋的運用,以齒性代償關閉前牙開咬,治療二級異常咬合,同時得到部份外觀的改善。 |
英文摘要 | Open bite develops because of interaction of many etiologic factors. Hereditary factors include deviation in vertical relationship of the craniofacial growth. Environmental factors include variations in dental eruption and alveolar growth, disproportionate neuromuscular growth or malfunctions of the tongue or oral habits. Obviously, open bite is much more difficult to treat and tends to relapse. The selection of treatment modalities for open bite depends on etiologic factors, severity and intervention timing. The treatment for open bite problems ranges from simple habit control procedures, tooth movement, to complex surgical procedures. This case report is presented in a 14-year-old girl who had a Class Ⅱ malocclusion with anterior open bite. After extraction of 4 first premolars, the girl was successfully treated with traditional edgewise appliances combined with short-term class Ⅱ elastics. Bite closure was achieved by extruding and retracting upper anterior teeth. Class Ⅰ occlusion was obtained and esthetic was partially improved at the same time. |
