摘　　要：目的评价Forsus功能矫治器结合MBT直丝弓固定矫治器治疗生长发育期Ⅱ类错下颌后缩患者的临床疗效。方法应用Forsus功能矫治器联合MBT直丝弓固定矫治器对15例(男9例,女6例,平均年龄13.2岁)替牙列晚期或恒牙列早期,以下颌后缩为主的骨性Ⅱ类错患者进行矫治。每位患者治疗前后均接受头颅定位侧位片扫描。对Forsus功能矫治治疗前后头颅定位侧位片的18个项目进行测量,并采用配对t检验对测量结果进行分析。结果矫正结束后,所有患者的牙齿排列整齐,双侧磨牙及尖牙达到中性关系,前牙浅覆浅覆盖,Ⅱ类面型及下颌后缩得到明显改善,侧貌也得到显著改善。头影测量分析显示SNA、ANB、UI/SN、OJ、UL-ELine、LI-ELine等在治疗结束后减小,差异有显著性;SNB、U1/PP、LI/MP、L6/PP、U6/PP、鼻唇角及颏唇角增大,差异有显著性。结论 Forsus功能矫治器可较好的使下颌前移,对下颌后缩患者是一种容易接受且疗效显著的治疗方案。Objective To evaluate the effect of Forsus appliance combined with MBT straight wire appliance on adolescent class Ⅱ malocclusion with mandibular retrusion. Methods Fifteen skeletal class Ⅱ patients in the 1ate mixed or early permanent dentition were included into this study. There were 9 boys and 6 girls. Lateral cephalograph and panoramic were taken for each patient before and after treatment. Eighteen measurements of cephalometrics before and after the treatment of Forsus combined with MBT straight wire appliance were carried out. Pared t test was used. Results After treatment,the SNA and ANB angles,UI/SN,OJ,UL-ELine,LL-Eline of the patients were decreased significantly. SNB,U1/PP,L1/MP,L6/PP,U6/PP and Sn-A＇-UL,LLB＇-Pos angles increased significantly. Conclusion The mandible grew forward after the treatment of Forsus appliance combined with MBT straight wire appliance and it was an acceptable and effective treatment strategy for adolescent class Ⅱ malocclusion with mandibular retrusion.
