摘　　要：目的 通过CBCT研究Forsus矫治器对生长发育期患者颞下颌关节的影响。方法 选取28例(男性14例,女性14例)生长发育期的安氏Ⅱ类错(牙合)患者,采用直丝弓矫治配合Forsus矫治器导下颌向前。每位患者在治疗前后均行CBCT扫描,使用Invivo 5软件对患者治疗前后的颞下颌关节有关数据进行测量。结果 治疗后SNB增加,ANB减小;关节窝宽度增加,关节结节倾斜角减小;髁突顶部矢状面面积、髁突顶部冠状面面积增加,差异有统计学意义(P<0.05);男性患者髁突体积、髁突顶部高度增加,髁突前后径减小,差异有统计学意义(P<0.05)。颞下颌关节窝面积、关节窝矢状总间隙面积、关节间隙、髁突内外径、髁突最大轴面面积不变(P>0.05)。结论 Forsus矫治器治疗后,髁突与关节窝相对位置关系不变,关节窝形态及髁突顶部形态改建,男性较女性髁突改建更明显。Objective To study the effect of Forsus appliance on temporomandibular joint in patients with growth and development by CBCT.Methods Twenty-eight patients(14 males,14 females)with Class II malocclusion during growth and development were selected,and the straight wire appliance and Forsus appliance were used to guide the mandibular forward.Each patient underwent CBCT scan before and after treatment.Measured the relevant data of temporomandibular joint before and after treatment by using Invivo 5 software.Results After treatment,SNB increased,ANB decreased.The width of the mandibular fossa increased,the inclination angle of articular tubercle decreased.The sagittal area of the apical condyle and the coronal area of the apical condyle increased,and the difference was statistically significant(P<0.05).In male patients,the volume of condyle,the apical height of condyle increased,and the anteroposterior diameter of the condyle decreased,and the difference was statistically significant(P<0.05).The mandibular fossa surface area,the sagittal total joint space,joint space,inner and outer diameter of condyle,maximum axial surface area of condyle unchanged(P>0.05).Conclusion After treatment with Forsus appliances,the relative position relationship between the condyle and the joint fossa remains unchanged,and the morphology of joint fossas and the apical condyle are modified.Condylar modification is more pronounced in males than females.
