摘　　要：目的:探究青少年骨性高Ⅱ类高角病颅面部特征及种植钉支抗结合MBT矫治技术临床效果。方法:选取2015年1月至2018年1月在我院治疗的青少年骨性Ⅱ类高角病例将所有患者分为联合组(30例)及对照组(30例),联合组给予种植钉支抗联合MBT直丝弓正畸技术治疗,对照组给予MBT直丝弓正畸技术配合非种植体支抗治疗。比较两组手术总有效率;比较两组手术前后磨牙位移差异、上中切牙凸距差异、上中切牙倾斜角度差异;统计两组患者治疗期间牙根吸收、牙周病变等并发症发生情况。结果:经X线头颅定位分析得,高角病组垂直方向ALFH/PLFH、U1-L1/N-Me、ANS-U1/N-Me、Me-l1/N-Me大于正常值,高角病组软组织鼻唇角(Cm-SN-Ls)、H2角(NB-PgLs)大于正常值(P<0.05);联合组总有效率高于对照组,治疗期间并发症发生率低于对照组(P<0.05);治疗后联合组磨牙位移差异小于对照组,上中切牙凸距差异、上中切牙倾斜角度差异大于对照组(P<0.05)。结论:青少年骨性Ⅱ类高角病颅面部特征为上颌前突、下颌后缩,种植钉支抗结合MBT矫治技术治疗青少年骨性Ⅱ类高角病有效率高,且能降低术后并发症发生率。Objective:To explore the craniofacial features of adolescent skeletal type-II high-angle disease and the clinical effect of implants anchorage combined with MBT orthodontic technique.Methods:A total of 70 adolescents with skeletal type-II high-angle disease who were treated in the hospital from January 2015 to January 2018were enrolled.The adolescents were divided into combination group(30 cases)and control group(30 cases)by random number table method.The combination group was treated with implants anchorage combined with MBT straight wire orthodontics,while control group was treated with MBT straight wire orthodontics combined with non-implant anchorage.The total response rate of surgery,differences in molar displacements,convex distance and inclination angle of maxillary central teeth before and after surgery were compared between the two groups.The occurrence of complications such as root absorption and periodontal lesions during treatment in both groups was statistically analyzed.Results:X-rays head positioning analysis showed that ALFH/PLFH,U1-L1/N-Me,ANS-U1/N-Me and Me-l1/N-Me in vertical direction in high-angle disease group were greater than normal values,soft tissue nasolabial angle(Cm-SN-Ls)amd H2 angle(NB-PgLs)were greater than normal values(P<0.05).The total response rate of surgery in combination group was higher than that in control group,while incidence of complications during treatment was lower than that in control group(P<0.05).After treatment,differences of molar displacements in combination group were less than those in control group,while difference in convex distance and inclination angle of maxillary central teeth were greater than those in control group(P<0.05).Conclusion:Craniofacial features of adolescent skeletal type-II high-angle disease include maxillary protrusion and mandibular retraction.The effective rate of implants anchorage combined with MBT orthodontic technique is high in treatment of adolescent skeletal type-II high-angle disease,which can reduce incidence of postoperative
