舌側矯正治療模式的改變

A Paradigm Shift in Lingual Orthodontics–Literature Review

現代齒顎矯正技術因為電腦科技的進步以及病人在矯正治療過程中對美觀的要求而有顯著的變化。舌側矯正早在1972年就被發展出來，當時也曾紅極一時。但由於臨床操作困難、費時以及矯正醫師對治療結果的不滿意，舌側矯正仍稱不上主流。拜電腦科技所賜，從1990年開始舌側矯正又再次受矚目。各式新型舌側矯正器陸續被推出，朝著更小巧讓病人更舒服去改良，甚至發展出依照個人獨一無二的舌側面製作出來的客製化矯正器。配合數位化的治療計畫、電腦模擬模型建立，甚至電腦輔助矯正線的彎製，將以往繁瑣的舌側矯正技工部分化繁為簡。本篇最主要的目的是針對「舌側矯正」這主題，將近年來發表的文獻回顧，做一歸納、整理，希望能帶給各位臨床醫師較全面的概念。

So far, the biggest changes in technical aspects of lingual orthodontics include development of patient and orthodontist friendly lingual treatment system with new appliances and digital technology for computerized treatment plan modeling and wire bending. Lingual orthodontics is no longer difficult nor complicated technique. We are now entering new era of lingual orthodontics. The purpose of this article is to review the history, biomechanics, accuracy, caries outcome and patient's perspective of lingual orthodontics.
