    [摘要]目的：通过锥体束CT(Cone beam computed tomography，CBCT)研究Forsus矯治器对生长发育高峰后期患者颌骨及颞下颌关节的影响。方法：选取42例生长发育高峰后期的安氏Ⅱ类错牙合患者，行Forsus功能矫治的20例患者纳入实验组，未行功能矫治的22例患者纳入对照组，治疗前后均进行CBCT扫描。结果：治疗后，实验组和对照组B点前移量[(3.00±1.46)mm、(-0.63±2.81)mm]，ANB角度变化[(-1.76±0.82)°、(-0.75±1.06)°]，关节窝深度改变[(-0.02±0.74)mm、(0.82±0.89)mm]，关节结节倾斜角变化[(-3.97±7.32)°、(4.11±5.25)°]，髁突顶部高度变化[(0.60±0.82)mm、(0.06±1.09)mm]，髁突顶部冠状面面积变化[(15.82±9.46)mm2、(7.45±15.35)mm2]及牙合平面角变化[(0.75±2.12)°、(-0.55±1.64)°]各项指标比较，差异均有统计学意义。结论：Forsus矫治器可以导致下颌骨位置前移及颞下颌关节形态的适应性改建，治疗后牙合平面顺时针旋转。
