以下是由文獻中整理出來有關twin block的臨床療效
1)Twin-block矫治器对安氏Ⅱ类1分类具有矫形作用,可以诱导下颌功能性前移,抑制上颌生长,同时使得上下颌牙及牙槽骨发生改变,从而协调上下颌关系,改善面型.
2)Twin block矫治器可促进下颌生长,改善前牙的覆牙合覆盖关系.结论 Twin
block矫治器对治疗早期安氏Ⅱ1类错牙合可取得明显的骨骼改变,降低Ⅱ期矫治的难度.
3)Twin-block矫正器在一定程度上促进了下颌骨的发育,改善了Ⅱ类骨骼关系和(牙合)关系.
4)Twin-block矫治器是治疗下颌后缩畸形的高效矫治器之一,只要病例选择恰当,就能恢复正常咬合功能及面貌美观的疗效
5)对青春发育期安氏Ⅱ类错(牙合)采用Twin-block矫治器进行治疗,可获得较满意的效果.
6)Twin-block矫治器用于早期以下颌功能性后缩为主的安氏Ⅱ类Ⅰ分类错(牙合)的功能性矫治,可取得明显的牙(牙合)骨骼的改变
7)安氏Ⅱ1类错(牙合)畸形组功能矫治可使舌骨前上移位;增加上气道口咽段间隙,特别是舌根后气道间隙.
8)Twin-block能有效减小前牙覆盖,矫正磨牙关系,改善软组织侧貌,并增强Ⅱ类错(牙合)下颌骨的生长.
9)Twin-block矫治器治疗生长快速期安氏Ⅱ类1分类错(牙合)患者,可有效改善前牙覆盖和磨牙关系.这种改善包括骨骼效应和牙齿效应,其中下颌骨矢状方向的生长较为显著
10)Twin block作为一种功能矫治器,在安氏Ⅱ类错的治疗上有着独到的矫治效果.作者采用Twin block与固定矫治器相结合的双期矫治,对替牙晚期和恒牙早期较严重的由于下颌后缩引起的Ⅱ类错进行治疗,取得了满意的临床疗效.
11)Twin-block主要促进下颌生长
,口外弓颈牵引联合固定矫治器主要抑制上颌及上切牙向前生长,两种方法均能有效矫正生长期Ⅱ类错(牙合),改善软组织侧貌 ,且均未产生不利的垂直向变化.
12)Twin
block 矫治器可促进下颌生长；同时引起上切牙舌倾，下切牙唇倾。结论：Twin block
矫治器可产生明显的生长改良效果。

bite jumping screw的說明書ps:要使得矯正成功,以下的戴用注意事項請留意:
1 Wear the appliance full time. If you have any problems wearing the appliance contact the practice.
(請全日戴用,若有任何問題,請即刻與我們聯絡)
2 Take the appliance out for cleaning
your teeth, contact sports and swimming. You should wear it at meal times. This
requires a little practice but is worth the effort.
(若要刷牙,請先將裝置移除於口腔外,在劇烈性的體育運動與游泳時請移除,請儘量在進食也戴著吃,這需要一些練習,這是值得的)
3 At first the appliance may be a
little uncomfortable. Any sore spots will usually pass off as you get used to
your appliance. If the discomfort persists don't wait for the next appointment
but contact the practice and an appointment will be made for you to be seen as
soon as possible. You may produce a little more saliva initially but this will
soon return to normal. You must try to keep the blocks in contact at all times.
You will soon learn to speak with your teeth together.
(剛開始戴用時可能有一點不舒服,若有痛點,慢慢會適應的,若是不舒服的現象持續著請約診立即回院處理,不需等到下次的回診再處理,其次,口水增多是正常的現象,慢慢習慣了就不會了,請儘量戴用,學習戴用的時候也能說話)
4 Keep the appliance very clean by
brushing thoroughly with a toothbrush and pay particular attention to brushing
your teeth and gums for three minutes at least twice a day.
(請用一般的牙刷來清洗裝置,同樣的請特別留意也把您的牙齒與牙齦每天至少兩次,每次3分鐘的清洗)
5 The twin block appliance is expensive to make and so you must take care of the
appliance. When the blocks are not in the mouth store the appliance in a plastic
box and DO NOT wrap in tissue paper - many appliances
have been thrown away after being wrapped in a napkin after lunchtime. If the
appliance breaks or becomes distorted contact the practice immediately. If lost or broken beyond repair the extra fee for replacement is
currently required (這項裝置的製作費用較昂貴,所以要小心保管好,當裝置不在口腔中,
請一定要放在保存盒內,切記!不要用衛生紙包起來,很多活動矯正裝置都是經由這樣在用餐的時候被丟掉不見的,若是裝置有裂掉或變形,請立即與我們聯絡,若是遺失或是斷裂無法修復,重新製作一付是需要額外再收費的請特別注意!)
6 Remember that you should continue to
visit your own dentist for regular inspections and if necessary treatment during
the orthodontic treatment.
(記住,一定要配合醫生的回診,因為這是觀察您改善情形的最好方法,醫生可以進一步留意您的治療進程)
7 Twin block therapy typically lasts
12 months and is followed by a further 20-24 months fixed appliance treatment.
(此項裝置的治療會持續12個月左右,若有必要,接著會有1年半~2年的固定矯正器的療程,請留意!)
8 Fluoride mouth rinse should be used
daily throughout orthodontic treatment and disclosing tablets should be used
regularly to help you keep your teeth clean.
(含氟漱口水的使用是有助益的,若有必要,可以用牙菌斑顯示劑來檢測您刷牙是否刷乾淨)
9 Bring you toothbrush every time you come and see us and always clean your teeth thoroughly just before each
appointment. (每次回診, 請將口腔清洗乾淨)
