摘　　要：目的:通过锥体束CT(Cone beam computed tomography,CBCT)研究Forsus矫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)mm^(2)、(7.45±15.35)mm^(2)]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。Objective The effect of the Forsus appliance on the morphological structure of the jaws and temporomandibular joints in patients during late peak period was studied by CBCT.Methods 42 patients with Class Ⅱ malocclusion during late peak period were selected,20 patients who underwent Forsus functional treatment were included in the experimental group,22 cases without functional treatment were included in the control group,and CBCT scans were performed before and after treatment.Results These differences between experimental group and control group were statistically significant:B-point advance[(3.00±1.46)mm,(-0.63±2.81)mm],change of ANB angle[(-1.76±0.82)°,(-0.75±1.06)°],change of mandibul a r fos s a he ight[(-0.02±0.74)mm,(0.82±0.89)mm],change of inclination angle of articular tubercle[(-3.97±7.32)°,(4.11±5.25)°],change of apical height of condyle[(0.60±0.82)mm,(0.06±1.09)mm],change of coronal area of the apical condyle(15.82±9.46)mm^(2),(7.45±15.35)mm^(2)and change of occlusion plane angle[(0.75±2.12)°,(-0.55±1.64)°].Conclusion Forsus appliances can lead to anterior displacement of the mandible and alteration of the morphology of the temporomandibular joint,with the occlusal plane rotating clockwise after treatment.
