@打開咬合(bite opening)的方法 @ 崇愛牙醫診所(資料重建中,歡迎新舊朋友)

以下的這一段話非常的經典,若是您在操作bite
opening前,一定要牢記這一段話!!

A word of advice: do not do any other mechanics until the bite is
opened. Do what it takes (and be patient!) to get the bite opened before
progressing in the case. You will save a ton of time in the
long run. (from: http://practicalorthodontics.blogspot.com/)

It is more difficult to open the bite in extraction cases than in non-extraction
cases.(拔牙案例比不拔牙案例更難打開咬合)

常常在矯正的過程當中總會遇到咬合加深的情形,通常會藉著許多種方法來打開,比如在線上做補償曲線,molar tip back
bends(大臼齒後傾彎),口外力J型鉤,INTRUSION ARCH(壓入弓),咬合板(或叫颌墊),迷你微植體(MIA),多用弓(UTILITY
ARCH),斜面導板,搖椅弓,BURSTONE SECTION ARCH(片段弓),LEVER ARM(懸力臂),T型曲(T LOOP)與靴型曲(L
LOOP),這些裝置或操作可以幫助在咬合變深的狀態下依所需要的情形操作,可以得到一些效果,有時也必需聯合使用,方能竟其功
