摘　　要：【目的】观察应用新型可摘式钟摆矫治器矫治安氏Ⅲ类错颌伴有上颌第二前磨牙拥挤青少年病例的临床疗效。【方法】对采用新型可摘式钟摆矫治器的16例患者分别进行矫治前、后的模型测量和侧位片X线头影测量分析,其结果进行配对t检验。【结果】平均3.8个月可增加磨牙近中距离5mm,SNA角、A点凸度等明显增加(P<0.05)。【结论】新型可摘式钟摆矫治器在有效地推上颌磨牙向远中移动的同时,能改善患者面中部凹陷的侧貌,而且不影响患者的口腔卫生维护与进食,在安氏Ⅲ类错颌伴有上颌第二前磨牙拥挤的青少年患者中具有临床推广价值。【Objectives】 This study was designed to evaluate the treatment effects of a new movable molardistalization appliance for distal movement of maxillary first molars on Angle＇s Class Ⅲ malocclusion adolescence patients with the second premolar crowded. 【Methods】 Sixteen patients were treated by a new movable molardistalization appliance. Cephalometric analysis and model measurement was carried out before and after the treatment. Data were analyzed by paired t-test. 【Results】 The molars were distalized 5 mm during an average time of 3.8 months. There were significant increases in the Angle SNA and A-NPg （P〈0.05）. 【Conclusion】 It was a effective way to get space and improve patient＇s profiles on Angle＇s Class Ⅲ malocclusion adolescence patients with the second premolar crowded by the new movable molardistalization appliance. It was also conducive to patient＇s oral hygiene.
