目的 探讨传动直丝弓技术治疗骨性Ⅲ类错(牙合)畸形的特点.方法 20例经传动直丝弓技术治疗的骨性Ⅲ类错(牙合)畸形患者,分析其治疗前后的头颅定位侧位片,评价患者矫治前后软硬组织的变化,总结传动矫正技术的特点.结果 与矫治前对比,矫治患者侧貌和咬合关系有明显改观.矫治后的Wits值由(-2.45±1.78) mm改善为(-1.13±0.92)mm,ANB角由(-1.25±1.63)°增大为(0.78±2.79)°,矫治前后的差异有统计学意义(P＜0.05).矫治后患者上、下唇突点到SnPg’平面的距离之差由(-3.38±1.48)mm变为(2.09±1.55) mm,面型角由(2.75±1.47)°变为(7.51±1.87)°,矫治前后的差异有统计学意义(P＜0.05).结论 传动直丝弓技术是治疗骨性Ⅲ类错(牙合)畸形的有效手段.
目的 探討傳動直絲弓技術治療骨性Ⅲ類錯(牙閤)畸形的特點.方法 20例經傳動直絲弓技術治療的骨性Ⅲ類錯(牙閤)畸形患者,分析其治療前後的頭顱定位側位片,評價患者矯治前後軟硬組織的變化,總結傳動矯正技術的特點.結果 與矯治前對比,矯治患者側貌和咬閤關繫有明顯改觀.矯治後的Wits值由(-2.45±1.78) mm改善為(-1.13±0.92)mm,ANB角由(-1.25±1.63)°增大為(0.78±2.79)°,矯治前後的差異有統計學意義(P＜0.05).矯治後患者上、下脣突點到SnPg’平麵的距離之差由(-3.38±1.48)mm變為(2.09±1.55) mm,麵型角由(2.75±1.47)°變為(7.51±1.87)°,矯治前後的差異有統計學意義(P＜0.05).結論 傳動直絲弓技術是治療骨性Ⅲ類錯(牙閤)畸形的有效手段.

Objective To investigate the effect of skeletal class Ⅲ patients treated by transmission straight wire appliance.Methods 20 skeletal class Ⅲ patients were well treated with transmission straight wire appliance.Their lateral cephalograms before and after the treatment were analyzed to summarize the advantages of this technique.Results Both facial appearance and occlusal functions of these patients were improved remarkably.After treatment,Wits changes from (-2.45± 1.78)mm to (-1.13±0.92)mm and ANB changed from (-1.25±1.63)° to (0.78±2.79)°(P＜ 0.05).The difference between the distance of the upper lip and lower lip to SnPg'planechanged from (-3.38±1.48) mm to (2.09±1.55) mm (P＜0.05).FCA changed from (2.75±1.47)°to (7.51± 1.87)°(P＜0.05).Conclusions Transmission straight wire technique is effective in treatment of skeletal class Ⅲ patients.
