摘要

臨床上用來治療在混合齒列期之前牙反咬的技術有很多，本病例報告是分別使用固定及活動式的斜面咬合板治療兩位患者。患者A是一位8歲大的女孩，其右上恆門齒呈現反咬。患者B是一位10大的女孩，其左上恆側門齒呈現反咬，兩位患者同時合併有矢向面和橫向面的下顎骨功能性位移。積極治療的總時間分別為 2個月和3個月；在隨後的6個月也能成功地維持治療效果。這樣的阻斷性矯正治療方式除了兒童牙科及矯正醫師外，一般牙科醫師也能有效的運用，藉此改善混合齒列期之前牙反咬之咬合異常。

There are different techniques have been used to correct anterior crossbite in mixed dentition. This two clinical case report illustrates the treatment using fixed and removable inclined bite plane to correct anterior crossbite with mandibular functional shift during the mixed dentition. The patient A was an 8-year-old girl with a crossbite of the maxillary right permanent central incisor. ¬e patient B was a 10-year-old girl with a crossbite of the maxillary le permanent lateral incisor, both two cases expressed by a mandibular functional shift in the sagittal and transverse dimensions. The total active treatment time were 2 months and 3 months respectively; the treatment outcomes were successfully maintained for the subsequent 6 months. Pedodontists and orthodontists, as well as general practice, may find this interceptive orthodontic treatment technique useful in managing anterior crossbite cases of the mixed dentition and utilizing the discussion for further clinical guidance.
