摘　　要：目的:研究腭部微螺钉-横腭杆-摇椅弓结合的支抗系统治疗上颌前突的临床效果。方法:取14例需要强支抗内收前牙的上颌前突患者(拔除14、24、34、44),直径1.2 mm横腭杆与腭部6 mm微螺钉结扎固定作为支抗系统,摇椅弓作用下,直丝弓固定矫治技术一步法内收上前牙,取治疗前后头颅侧位片进行定点测量,比较第一、二恒磨牙矢状向和垂直向位置变化;取治疗前后模型,测量双侧第一恒磨牙中央窝宽度,进行比较分析。结果:上颌第一、二磨牙未见明显矢状向和垂直向位置变化(P>0.05),第一磨牙间宽度未见明显变化(P>0.05)。结论:微螺钉种植支抗与横腭杆、摇椅弓结合的方式,可在长、宽、高三维向上实现上颌强支抗。Objective To evaluate the effect of the miniimplant anchorage system combined with transpalatal arch (TPA) and reverse curve archwire in orthodontic treatment of maxillary protrusion patients.Methods 14 maxillary protrusion patients were treated with extraction of four premolars.The trans-palatal arch of 1.2 mm in diameter was ligated and fixed with a mini-implant of 6 mm beside median palatine suture.The extraction space was closed by one-step method and the sliding mechanical straight-wire archwire with rocking chair curve.The sagittal and vertical positions of the first and second molars were evaluated by lateral cephalometric radiographs taken before and after treatment.The molar width was compared by the model measuring result before and after treatment.Results There was no significant difference was in the sagittal and vertical positions of the maxillary first and second molars (P>0.05).There was no significant difference was in the width between the first molars (P>0.05).Conclusion Palatal miniimplant anchorage can be combined with transverse palatal arch as maximum molar anchorage in three dimensions of length,width and height.
