Closure of large space｜【Chris Chang Ortho】CC743

[Clinical tip] This presentation shares three key tips in closing large spaces in the posterior segment. First, place the brackets in a mesial-down position. Second, lower the friction by not bonding the last tooth. Third, apply buccal-lingual mechanics to close the space. 本篇報告分享了關閉後牙大空間的三個秘訣。第一，將矯正器以mesial-down的方式黏著。第二，讓最後一顆牙不黏矯正器，減低摩擦力。最後，使用buccal-lingual mechanics來關閉空間。
