正頜外科有哪些基本手術方法?

  正頜外科有哪些基本手術方法?隨著現代正頜外科基本理論的不斷豐富、術前術後正畸技術的完善及各種輔助外科技術的綜合應用,現代正頜外科經歷了由多階段手術到一次完成多個手術組合,從多種手術術式矯正一類牙頜面畸形到少數經典手術術式矯治多種牙頜面畸形的發展過程。

今天,標準的同期雙頜外科手術(包括上頜骨的lefortⅠ型截骨術、下頜升支截骨術和水準截骨頦成形術)已成為正頜外科應用最廣泛的外科基本技術。
由於堅固內固定技術的廣泛應用,目前臨床完成的下頜升支截骨術主要為下頜升支矢狀劈開截骨術。

若熟練掌握正頜外科手術的基本操作要領,在嚴密的術前診斷和設計的指導下巧妙地結合3種基本術式和其他輔助手術,就能成功地矯治臨床上常見的多種牙頜面畸形,並取得良好矯治效果。
