SURGICAL CORRECTION OF MANDIBULAR PROGNATHISM WITH SPACED DENTITION - A CASE REPORT

骨姓三級異常咬合伴隨多處齒間間隙之手術矯正治療-病例報告

摘要


多處齒間間隙常見的治療包括以齒顎矯正的方式關閉間隙或是重新分配空間後以牙體復形的方式治療;本病例報告提出以齒顎矯正治療將多餘空隙集中於下顎根尖下截骨術的切線處,以手術關閉多餘空間以提供更有效率的治療方式。本病側是一位25歲男性合併骨性三級異常咬合與多處齒間間隙,經全口齒顎矯正治療將空間集中於雙側下顎犬齒與第一小臼齒之間後,在正顎手術以下顎雙側矢向骨切開術與頦成形術治療下顎前突的同時合併下顎根尖下截骨術關閉此多餘空隙,治療後無論咬合與外觀皆獲得大幅改善。

並列摘要


This 25-year-old male was characterized with mandibular prognathism and spaced dentition. We applied bilateral sagittal split osteotomy and genioplasty to set back the mandible and the prominent chin. The excess spaces of lower dentition were consolidated and then closed surgically by anterior subapical osteotomy. After treatment, his facial esthetics and occlusion were improved significantly. In the spaced dentition, the space closure by anterior subapical osteotomy after space consolidation may provide a more efficient alternative treatment.
