      活動矯治器優缺點各是什麽?



    活動矯治器是一種牙颌畸形的矯治裝置,它可由患 者或醫生自由摘戴,摘下時不會對矯治器造成損害;活動 矯治器與牙冠及口腔黏膜表面的接觸關系,主要是醫生 根據矯治進展的需要來隨意增減那些能産生矯治力的附 件,從而達到矯正錯箝的目的。活動矯治器包括機械矯 治器、功能矯治器兩大類。

    

    

    (1) 活動矯治器的優點:

    1) 可自行摘戴,便于洗刷,有利于口腔衛生的維護;

    2) 不損傷牙體和牙周組織;

    3) 患者可自選適應矯治力的強度;

    4) 不影響美觀和社交;

    5) 設計簡單、費用低廉。

    

    (2) 活動矯治器的缺點:

    1)固位力差,治療效果欠佳;
