摘　　要：选择上颌轻中度前突的安氏Ⅱ类患者15例,男5例,女10例,年龄16~26岁。DamonⅢ矫治器常规排齐整平上下颌牙列。采用微螺钉种植体植入颧下嵴区,不锈钢方丝上颌全牙列连续结扎,远中移动上颌牙列,治疗前后进行X线头影测量分析比较。治疗后U1-NA（°）减小2.51±1.52（P〈0.01）,U1-NA（mm）减少4.56±1.25（P〈0.01）,UL-EP（mm）减少2.21±1.83,U6EPTV（mm）减少2.93±1.17,U6A-PTV（mm）减少1.56±0.95（P〈0.01）,SNA（°）及下颌牙列参数无显著变化（P〉0.05）;双侧磨牙为中性关系。15 cases, 5 males and 10 females, aged 16 -26 years, with Class Ⅱ division maxillary mild to moderate protrusion were includ- ed. Damon III appliance was used to arrange the upper and lower dentition. Stainless steel micro-screw implants were implanted in zygomatic crest to provide the best bone anchorage, stainless steel rectangular wire was used for maxillary complete dentition continuous ligation and maxillary teeth distal movement. X- ray cephalometry study showed that U1- NA （ ° ） reduced by 2.51 ± 1.52 （P 〈 0.01 ）, U1- NA （ram） re- duced by 4.56 ± 1.25, UL-EP（mm） reduced by 2.21 ± 1.83, U6E-PTV （mm） reduced by 2.93 ± 1.17, U6A-PTV （mm） reduced by 1.56 ± 0.95, SNA（ ° ） and the mandibular parameters were not significantly changed（P 〉 0.05）, centric jaw relation of bilateral molar was obtained.
