目的 评价成人高角开(牙合)患者应用Tweed矫治技术治疗的临床疗效.方法 7例成人高角开(牙合)患者应用Tweed矫治技术进行治疗,在矫治前、后拍摄X线头颅侧位片,应用Tweed-Merrifiled颅面分析法对测量指标进行比较.结果 7例患者牙(牙合)畸形得到了矫治,面形得到了较大改善.治疗前、后的配对t检验显示,FMA平均减少了2.4°(P＜0.01),IMPA平均减小了10.0°(P＜0.01),ANB角平均减少了1.8°(P＜0.01),Z角平均增大了9.2°(P＜0.05).结论 通过Tweed矫治技术对垂直向的控制,即使是成人患者也实现下颌骨的前上旋转,(牙合)平面的前上旋转,前面高得到了控制,面形得到了较大改善.对于高角开(牙合)患者,Tweed矫治技术也不失一种很好的选择.
目的 評價成人高角開(牙閤)患者應用Tweed矯治技術治療的臨床療效.方法 7例成人高角開(牙閤)患者應用Tweed矯治技術進行治療,在矯治前、後拍攝X線頭顱側位片,應用Tweed-Merrifiled顱麵分析法對測量指標進行比較.結果 7例患者牙(牙閤)畸形得到瞭矯治,麵形得到瞭較大改善.治療前、後的配對t檢驗顯示,FMA平均減少瞭2.4°(P＜0.01),IMPA平均減小瞭10.0°(P＜0.01),ANB角平均減少瞭1.8°(P＜0.01),Z角平均增大瞭9.2°(P＜0.05).結論 通過Tweed矯治技術對垂直嚮的控製,即使是成人患者也實現下頜骨的前上鏇轉,(牙閤)平麵的前上鏇轉,前麵高得到瞭控製,麵形得到瞭較大改善.對于高角開(牙閤)患者,Tweed矯治技術也不失一種很好的選擇.

Objective To evaluate the clinical effects of Tweed technique in the treatment of adult high angle open-bite patients.Methods Seven adult high angle open-bite patients were treated using Tweed technique.Cephalograms before and after treatments were taken.Tweed-Merrifiled cephalomatric analysis method was applied to compare the differences between pre-and post-treatments.Results After treatment,FMA,IMPA and ANB angle were decreased by 2.4° (P＜0.01),10.0° (P＜0.01) and 1.8° (P＜0.01) on average,respectively.Z angle increased by 9.2° (P＜0.05) on average.Conclusions Even for adult patients,forward and upward rotation of mandibles and occlusion planes could be achieved with Tweed technique.The anterior facial heights were controlled and the profiles were improved greatly.
