摘　　要：目的:研究不同矢状骨面型青少年低角患者颞下颌关节形态及位置差异,探讨颞下颌关节与颅颌面部骨骼类型之间的关系。方法:选择11~16岁骨性Ⅰ、Ⅱ、Ⅲ类低角患者各20例做为研究组,骨性Ⅰ类均角患者20例作为对照组,拍摄CBCT并导入Invivo 5.2软件获取头颅侧位及双侧关节影像,测量并进行统计学分析。结果:(1)Ⅰ类低角组髁突长轴径和冠状面髁突宽度、Ⅱ类低角组关节间隙以及Ⅲ类低角组关节窝深度等与眶耳平面-下颌平面角呈显著负相关。(2)与对照组相比,Ⅰ类低角组关节前间隙(P=0.022)和Ⅱ类低角组关节窝深度(P=0.027)等明显较大,Ⅲ类低角组关节结节斜度(P=0.017)和髁突水平角(P=0.016)明显较小。(3)Ⅰ类低角组髁头角和关节结节斜度等(P<0.05)、Ⅱ类低角组关节内间隙(P≤0.01)以及Ⅲ类低角组髁头角(P<0.01)等均显示右侧小于左侧。结论:不同矢状骨面型青少年低角患者颞下颌关节髁突形态、对称性、关节间隙等存在显著差异,正畸治疗中应予以重视,持续关注其髁突生长状态,以达到正畸后长期稳定的治疗效果。Objective:To investigate the difference of TMJ morphology and position in low angle adolescent patients with different sagittal skeletal surface types,and to explore the relationship between TMJ and craniofacial skeletal types.Methods:Twenty patients with low angle of skeletal classⅠ,Ⅱ,andⅢaged 11-16 years were selected as the study group,and 20 patients with average angle of skeletal classⅠwere selected as the control group.The CBCT images were imported into Invivo5.2 software to obtain lateral cephalic and bilateral joint images,and the data were measured and investigated by statistical methods.Results:(1)There were significant negative correlations between FH-MP and condylar long axis diameter and condylar width in classⅠlow angle group,joint space in classⅡlow angle group and glenoid fossa depth in classⅢlow angle group.(2)Compared with the control group,the anterior joint space(P=0.022)in classⅠlow angle group and glenoid fossa depth(P=0.027)in classⅡlow angle group were significantly larger,and the articular eminence inclination(P=0.017)and horizontal condylar angle(P=0.016)in classⅢlow angle group were significantly smaller.(3)The condylar angle and articular eminence inclination(P<0.05)in classⅠlow angle group,mesial joint space(P≤0.01)in classⅡlow angle group,and condylar angle(P<0.01)in classⅢlow angle group showed that the right side was smaller than the left side.Conclusion:There are significant differences in the condyle shape,symmetry,and joint space of TMJ in adolescent patients with low angle of sagittal surface.Attention should be paid to the condyle growth status in orthodontic treatment,so as to achieve long-term stable treatment effect after orthodontic treatment.
