目的：研究双垫矫治器对下颌后缩的矫治效果，探讨双垫矫治器在安氏Ⅱ类远中错（表现为下颌后缩的侧面貌）矫治中的作用。方法：选择2012年4月-2013年12月来口腔科门诊就诊的下颌后缩患者60例，按矫治方法的不同分为研究组和对照组，研究组用双垫矫治器矫治下颌后缩；对照组又按拔牙位的不同分为对照组一和对照组二，对照组一采取上颌拔除两个第二双尖牙而下颌不拔牙的固定矫治，对照组二采取上颌拔除两个第一双尖牙而下颌拔除两个第二双尖牙的固定矫治。结果：双垫矫治器有效前移下颌，使下颌功能性改建，获得良好的侧面貌。而对照组一拔除上颌两个第二双尖牙下颌不拔牙，经固定矫治后，下颌位置无改变，上颌因拔牙矫治而朝后缩一部分，彰显平直脸型，且面下三分之一短。对照组二拔除上颌两个第一双尖牙和下颌两个第二双尖牙，经固定矫治后，上下颌皆因拔牙矫治而略朝后缩，更加重了下颌后缩的面型，呈现衰老消瘦的面容。结论：双垫矫治器的应用，使下颌前伸，纠正下颌后缩，极大地矫正了面貌，重塑了颜面美观。
目的：研究雙墊矯治器對下頜後縮的矯治效果，探討雙墊矯治器在安氏Ⅱ類遠中錯（錶現為下頜後縮的側麵貌）矯治中的作用。方法：選擇2012年4月-2013年12月來口腔科門診就診的下頜後縮患者60例，按矯治方法的不同分為研究組和對照組，研究組用雙墊矯治器矯治下頜後縮；對照組又按拔牙位的不同分為對照組一和對照組二，對照組一採取上頜拔除兩箇第二雙尖牙而下頜不拔牙的固定矯治，對照組二採取上頜拔除兩箇第一雙尖牙而下頜拔除兩箇第二雙尖牙的固定矯治。結果：雙墊矯治器有效前移下頜，使下頜功能性改建，穫得良好的側麵貌。而對照組一拔除上頜兩箇第二雙尖牙下頜不拔牙，經固定矯治後，下頜位置無改變，上頜因拔牙矯治而朝後縮一部分，彰顯平直臉型，且麵下三分之一短。對照組二拔除上頜兩箇第一雙尖牙和下頜兩箇第二雙尖牙，經固定矯治後，上下頜皆因拔牙矯治而略朝後縮，更加重瞭下頜後縮的麵型，呈現衰老消瘦的麵容。結論：雙墊矯治器的應用，使下頜前伸，糾正下頜後縮，極大地矯正瞭麵貌，重塑瞭顏麵美觀。

To study the effect of Twin-block appliance Orthodontics mandible recession,discuss the effect of Twin-block appliance orthodontics Class Ⅱdistoclusion(appeal that the profile of mandible recession). Method:60 patients with mandible recession in our hospital’s oral cavity department,from April 2012 to November 2013,were selected,and they were divided into treatment group and contrast group. According to the difference method of Orthodontics,the treatment group was treated with Twin-block appliance orthodontics mandible recession. The contrast group was proceed to divided into contrast group one and two,according to the different teeth’s extraction. The contrast group one was treated with extracted two maxillary second premolar and by straight wire appliance(SWA),but the mandible wasn’t extracted any teeth. The contrast two was treated with extracted two maxillary first premolar and two mandibular first premolar and by SWA. Result:Twin-block appliance moved ahead the mandible efficiently,let the function of the mandible to rebuild,got a very good profile. But the contrast group one,extracted two maxillary second premolar but the mandible wasn’t extract any teeth and by SWA,the mandible’s place had no change,appeared a flat face,and one three of the face shorted. The contrast group two extracted two maxillary first premolar and two mandibular first premolar,by SWA,the maxilla and mandible moved back a little,enlarged the mandible recession,appeared a older slim face. Conclusion:Apply Twin-block appliance,moves ahead mandible recession,corrects the mandible recession, corrects face immensely,rebuilds the esthetic of the face.
