摘　　要：目的:探讨利用微种植钉支抗远移上颌全牙列治疗安氏II类错牙合畸形的临床治疗效果。方法:选取2014年10月-2016年10月笔者科室确诊收治的上颌轻中度前突的18例患者作为研究对象,采取非拔牙矫治,用微种植钉作为支抗体植入上颌颧牙槽嵴区,利用镍钛拉簧施加牵引力拉上颌全牙列整体向远中移动。对患者治疗前后头影测量及模型进行对比研究。结果:18例患者均获得较理想的治疗效果,磨牙关系变为中性关系,前牙达到正常覆牙合覆盖,患者侧貌得以改善;18例患者共计植入36颗微型种植钉,其中有2颗发生松动,其余34颗保持稳定而无松动,种植体周围软组织健康;治疗后,经过头颅侧位片进行测量,患者上颌双侧第一磨牙牙冠和牙根分别平均远中移动了3.17mm、2.77mm。上颌切牙牙冠和牙根分别平均远中移动了3.29mm、0.73mm,以上数值变化均有统计学意义(P<0.05);患者硬组织测量项目中MP-SN平均增大了1.22°,OP-SN平均增大了1.52°,两者数值变化均有统计学意义(P<0.05),其余的SNA、SNB、ANB、PP-SN、A-FHP变化均无统计学意义(P>0.05)。结论:运用微种植钉支抗远移上颌全牙列而矫治上颌轻中度前突的II类患者过程中,上牙列通过整体远移获得了有效的远中移动量,前牙覆牙合覆盖、后牙咬合关系恢复正常,患者侧貌有了明显的改善,收到了满意的治疗效果,但远期疗效还需要进一步观察。Objective To explore the use of Micro Implant Anchorage in distal movement of the entire maxillary arch in thetreatment of class II malocclusion clinical curative effect.Methods18cases diagnosed in our hospital from October2014toOctober2016of the maxillary protrusion in patients with mild to moderate as the research object,adopt the non extractiontreatment with micro implant as anchorage maxillary implant zygomatic ridge area,the entire maxillary arch applying tractionforce overall to far.Using nickel titanium coil springs on the comparative study of the measurement and model of cephalometricpatients before and after treatment.Results All the18patients get better treatment effect,grinding teeth become neutral,anteriorteeth to normal overbite He covered with profile can be improved;18patients were implanted in36Mini screws,including2teeth loosening,the remaining34remained stable and no loose,soft tissue around the implant health;after treatment,afterlateral cephalograms were measured in patients with bilateral maxillary first molars of crown and root average distal movement3.17mm,2.77mm.maxillary incisor crown and root respectively distalize3.29mm,0.73mm,the above numerical changes werestatistically significant(P<0.05);MP-SN hard tissue were measured in average increased by1.22°OP-SN,the average increaseof1.52°,the numerical changes were statistically significant(P<0.05),the rest of the SNA,SNB,ANB,PP-SN,A-FHP were notstatistically significant(P>0.05).Conclusion The use of Micro Implant Anchorage in distal movement of the entire maxillaryarch and II patients with mild to moderate maxillary protrusion in the upper dentition was effective in moving far far throughthe whole shift,anterior teeth overbite and overjet,posterior occlusion in patients with normal profile was improved obviously,and received satisfactory treatment effect,but the long-term effect needs further observation.
