摘要

對於嚴重骨性及齒列安格氏三級異常咬合的患者，傳統的治療需以齒顎矯正合併正顎手術，才能達到穩定的一級咬合，同時獲得顏面外觀上的改善。由於骨性錨定的進步以及發展，對於輕、中度骨性異常咬合的患者，提供了非手術治療的可能性。本病例報告一位下顎前突的三級異常咬合患者，在拔除第三大臼齒後，使用下顎兩側迷你骨板進行下顎整體牙齒的遠心移動(total arch distalization)，經過兩年的齒顎矯正治療後，前牙達成良好的水平覆咬及垂直覆咬，並使後牙建立在穩定的齒列安格氏一級咬合。治療完成後經過三年四個月追蹤，治療結果仍維持良好的穩定性。

The etiologies of skeletal Class Ⅲ malocclusion include excessive growth of the mandible, insufficient growth of the maxilla, or the combination of both. The ideal treatment for severe mandibular prognathism is a combination of orthodontic treatment with orthognathic surgery to setback the mandible. However, non-surgical approach using mini-implant anchorage could distalize the mandibular dentition and improve the occlusion if the skeletal discrepancy is mild to moderate.In this report, we present the treatment of a 20-year-old male patient with Class Ⅲ malocclusion and anterior crossbite. Mini-plates were implanted on anterior border of mandibular ramus and used as temporary anchorage devices for distalization of whole mandibular dentition. At the end of treatment, correction of Class Ⅲ malocclusion and anterior crossbite had been achieved. An examination 3 years 4 months after treatment revealed long-term stability of the treatment results.
